What You WillNeed to Print
Your printer is one of three parts of your printing solution. To print, you will also need print media and
software.
The printer can operate in standalone mode. It does not have to be connected to other devices or systems
to print.
Compatible media
Depending on the printer model (direct thermal or
thermal transfer), you will need appropriate media
to print.
Direct thermal printing uses chemically-treated,
heat-sensitive media that blackens when it
passes under the thermal printhead.Fordirect
thermal printing, you will need direct thermal
media.Ribbon is not required for direct thermal
printing.
Thermal transfer printing uses a heated ribbon to
produce durable, long-lasting images on a wide
variety of materials.For thermal transfer printing,
you will need thermal transfer media and thermal
transfer ribbon rolls (or a ribbon cartridge for
Ribbon Cartridge printer models).
You can use media that is of any supported
format. Depending on your printing needs, you
can use labels, tags, tickets, receipt paper, fanfold
stacks, tamper-proof labels, etc.
Use information from zebra.com/supplies or from
your reseller to identify and procure media for your
printer and for your specific uses.

The printer's primary user interface controls are on the front of the device.Two user interface options are
available on these printers.
• Standard User Interface — This interface serves basic printer control and status functions. Operating
status is provided by five icon indicator lights. These lights, together and in combination, provide a wide
range of printer status notifications. They are visible from a farther distance than the proximity needed to
read a printer display screen. See the Meaning of the Indicator Light Patterns on page 53.
• The printer user interface supports various routine tasks such as replacing printing supplies (labels,
receipt paper, transfer ribbon, or others). For example, you are notified of a media-out condition by
the color and state of two indicators.
• Each status indicator icon represent a functional area of printer operation (such as SUPPLIES or
NETWORK).
• Depending on the operational state of the printer, the printer's status indicator lights convey the
printer's status and activities(data downloading, over-temperature cooling cycle, or other) using a
variety of states:
• off (not lit—does NOT require your attention)
• litup red, green, or amber (orange yellow)
• blinking / flashing
• fading (bright to off)
• lighting up steady in a variety of patterns
• The color of these status indicators may be:
• Red — indicates that your attention is needed or that the printer is not ready to print.
• Green — indicates the printer is ready or functioning.
• Amber (orange/yellow) — indicates a busy or active process (data downloading, over-temperature
cooling cycle, etc.).
• Control buttons—You will use thesein various combinations to access internal utilities that calibrate
the printer to your media and change printer settings that are modifiable.
47
Controls and Indicators
• Color Display or Color Touch Display (available on some printer ZD printer models) — Provides
the means to easily set up and configure the printer. The display is customizable by all user types,
The interface includes all standard user interface controls and indicators to provide printer status
information.

Setup
Select a Location for the Printer
The printer and media need a clean and safe area with moderate temperatures for optimal print operations
Select a location for the printer that meets these conditions:
Condition Description
Surface Must be solid, level, and of sufficient size and strength to hold the printer
loaded with media (or in the case of fanfold media, stable and sturdy with the
media placed on the surface)..
Space The operating location for the printer must include enough space to open the
printer (for media access and cleaning), and enable access to connectivity
and power cords. Leave open space on all sides of the printer to allow for
proper ventilation and cooling.
IMPORTANT: Do not place any padding or cushioning material
under or around the base of the printer because this will restrict
airflow and could cause the printer to overheat.
Power Situate the printer within easy access of a power outlet.
Data communication
interfaces
Ensure that cabling and Wi-Fi or Bluetooth radios do NOT exceed the
maximum distance specified by the communication protocol standard or
product data sheet for this printer. Radio signal strength can be reduced by
physical barriers (objects, walls, etc.).
Data cables Cables should not be routed with or near power cords or conduits,
fluorescent lighting, transformers, microwave ovens, motors or other
sources of electrical noise and interference. These interference sources may
cause problems with communications, host system operation, and printer
functionality.
Operating conditions Your printer is designed to function in a wide range of environments.
• Operational temperature:40°F to 105°F (5°C to 41°C)
• Operational humidity:10% to 90%non-condensing
• Non-operational temperature:-40°F to 140°F (-40°C to 60°C)
• Non-operational humidity: 5% to 95% non-condensing
Install Printer Options and Connectivity Modules
If your printer will use any of the following printer options, you will need to install them before you proceed
with the printer setup.
• Wireless (802.11ac and Bluetooth 4.2) Module—See
Installing the Wireless Connectivity Module on
page 66
• Serial (RS-232 DB-9) Port Module—See Installing the Serial Port Module on page 63.

• Media Roll Core Size Adapters for 38.1 mm (1.5 in.), 50.8 mm (2.0 in.), or 76.2 (3.0 in.) I.D. media
cores.—For information on these adapters, see Media Roll Core Size Adapters on page 76. To install
the adapters, see Installing the Media Roll Adapters on page 76.
Attaching the Printer to a Power Source
CAUTION: Never operate the printer and power supply in an area where they can get wet.
Serious personal injury could result!
IMPORTANT: Ensure the appropriate power cord with a three-prong plug and an IEC 60320-C13
connector are used at all times. These power cords must bear the relevant certification mark of
the country in which the product is being used.
Set up your printer so that you can handle the power cord easily if needed. Some setup and
troubleshooting tasks may ask you to turn printer power OFF. When the instructions call for turning printer
power OFF, separate the power cord from the power supply receptacle or AC electrical outlet to ensure
that the printer CANNOT carry electrical current.
1. Plug the power supply into the printer’s DC power receptacle.
2. Insert the AC power cord into the power supply.
3. Plug the other end of the AC power cord into an appropriate AC electrical outlet.
NOTE: TheAC outlet (plug) end of the power cord varies by region.
The active power light turns green if power is on at the AC outlet.

Media Preparation for Printing
Purchase media that will suit your printing needs.Media does not ship with the printer.
You can use labels, tags, tickets, receipt paper, fanfold stacks, tamper proof labels or other print media
formats.Use the Zebra web site or your reseller may be able to help you select the right media for your
intended printing application.
To procure media that is specifically designed for use with your Zebra printer, go to
zebra.com/supplies.
During setup, use the same media that you would use for normal printer operation. This will help you
identify any setup or real-life application issues so you can address them right at the start.
Preparing and Handling Media
Careful handing and storage of your media is important in order to maximize print quality. If the media
becomes contaminated or dirty, it can damage the printer and cause defects in the printed image such as
voids, streaks, discoloration, and compromising of the adhesive.
IMPORTANT: During manufacturing, packaging, handling and storage, the outside length of
media may become dirty or contaminated. Remove the outside layer of the media roll or stack to
reduce the possibility of contaminants being transferred from the media onto the printhead while
printing.
Media Storage Guidelines
Follow these media storage guidelines for optimal print output.
• Store media in a clean, dry, cool, dark area.
NOTE: Direct thermal media is chemically treated to be heat-sensitive. Direct sunlight or heat
sources may ‘expose’ the media.
• Do NOT store media with chemicals or cleaning products.
• Leave media in its protective packaging and remove the packaging only before use.
• Many media types and label adhesives have a shelf life or expiration date. Always use the oldest, viable
(non-expired) media first.
Roll MediaTypes and Loading
The printers support the three basic types of media: continuous media, marked media, and label media.All
three types are loaded the same way for the printer models described in this guide.
• Continuous has no marks that define print length. These are typically used for receipts.
178
Setup
• Marked media comes with black lines, black marks, notches, or holes that help the printer sense print
length.
• Label media avails of the print sensor's ability to look through the media backing (liner) and sense the
beginning and end of labels on the roll.
The printer uses two sensing methods to accommodate a wide range of media:
• Center-area transmissive sensing for continuous media and gap/web label media.
• Full-width movable (reflective) sensing for print format (length) using black marks, black lines, notches,
or holes.
Setting Media Sensing by Media type
• For web/gap media, the printer senses the differences between the label and the liner to determine the
print format length.
• For continuous roll media, the printer only senses the media’s characteristics. The print format’s length
is set by programming (driver or software) or by using length of the last stored form.
• For black mark media, the printer uses its sensor to measure the print format length, from the first black
mark to the start of the next black mark .
• If using a label dispenser, load the media and proceed with Using the Label Dispenser Option on page
247.
• If using fanfold media, see Printing on Fanfold Media on page 243.
Loading Media
This procedure works for the Tear-Off (standard bezel), Label Dispense, and Media Cutting options that are
available to use with your printer.
1. Open the printer. Pull the release latch levers toward the front of the printer.
2. Open the media roll holders. Orient the media roll so that its printing surface will face up as it passes
over the platen (drive) roller. Pull the media guides open with your free hand and place the media roll on
179
Setup
the roll holders and release the guides. Verify the roll turns freely. The roll must not sit in the bottom of
the media compartment.
3. Pull the media so that it extends out of the front of the printer.
180
Setup
4. Push the media under both of the media guides.
5. Flip the media up and align the movable media sensor as appropriate for your media type.
For continuous roll receipt-type media
and for label media without black marks
or notches...
Align the media to the default center position.
181
For black mark (black line, notches or
holes), backed media...
Adjust the sensor position in such a way that the sensor
aligns to the center of the black mark.
Avoid the center area of the media so you only use
black-mark sensing for printing on black mark media.
Setup
A Web (gap) sensing standard operating position for the sensor (default)
B Off-center sensor position (use for black mark sensing only
Movable Sensor Adjustment
The movable sensor is a dual-function sensor. It provides transmissive (sees through media) and reflective
media sensing. The printer can use either sensing method, but not both simultaneously.
The movable sensor has a center array of sensors. This provides adjustable transmissive web (gap)
sensing to positions that match legacy Zebra desktop printer sensor locations and positions in between.
This also provides for use of some non-standard media variations or irregularly-shaped media.
The movable sensor allows the printer to use media with black marks or notches (holes through the media)
on the back side of the media (or media liner). The sensor aligns to the middle of black marks or notches
not in the center of the media roll to avoid web/gap sensing array.
182
Setup
Adjusting the Movable Sensor for Black Marks or Notches
Black mark sensing looks for non-reflective surfaces such as black marks, black lines, notches or holes
on the back of the media which do not reflect the sensor’s near infrared light beam back to the sensor’s
detector. The sensor light and its black mark detector are located next to each other, under the sensor
cover.
1. Position the movable sensor’s alignment arrow to the middle of the black mark or notch in the
underside of the media.
2. Verify that you have set the sensor alignment as far as possible from the edge of the media, where
100% of the sensor window is aimed within the region of the black mark.
NOTE: When printing, the media can move from side to side ±1mm (due to media variations
and edge damage due to handling). Notches cut into the side of the media can also become
damaged.
Adjusting the Movable Sensor for Web (Gap) Sensing
The movable sensor for web/gap sensing supports multiple positions.
The movable sensor’s default position is ideal for printing on most label types.
The adjustment range is from center to off-center positions. This adjustment is ideal for printing two labels
side by side on a roll.
The movable sensor adjustment range covers sensor positions use by legacy Zebra printers.
Web (gap) sensing with the movable sensor only functions when the movable sensor’s alignment arrow
points to any position on the alignment key.

Setup
Loading Roll Media for Cutter Models
If your printer has the optional cutter module installed, use these instructions to continue loading the roll
media.
1. Thread the media through cutter’s media slot and pull it out the front of the printer.
185
Setup
2. Close the printer. Press down until the cover snaps closed.
You may need a calibrate your printer for the media.See Running a SmartCal Media Calibration on page
199. The printer’s sensors must adjust to sense the label, the liner, and the distance between labels to
operate properly.
However, you do not have to recalibrate the printer's media sensors when you are loading the media with
the same physical specifications (size, label type) and vendor/batch. If this is the case, just press FEED
(Advance) to ready the new media for printing.
Thermal Transfer Roll Ribbon Loading
Thermal transfer printers have a flexible ribbon system that supports 74-meter and 300-meter ribbons
manufactured by Zebra. Your printer ships with 300-meter ribbon adapters to support non-Zebra ribbon
rolls.
The74-meter ribbon used with non-Zebra printers does NOT require non-Zebra ribbon adapters to operate
properly.
Transfer ribbons come in several varieties—and in some cases several colors—to match your application
needs. Transfer ribbons manufactured by Zebra are specifically designed for use with your Zebra printer
and Zebra brand media.For transfer ribbon rolls and other printing supplies, see zebra.com/supplies.
CAUTION—PRODUCT DAMAGE: Using non-Zebra media or ribbons that are NOT approved for
use with your Zebra printer may damage your printer or printhead.
186
Setup
Inner Diameter (I.D.) = 12.2 mm (0.5 in.) I.D. = 25.4 mm (1.0 in.)
• To ensure optimal print results, match the media and ribbon types.
• To protect the printhead from wear, always use ribbon that is wider than the media.
• For printing on Direct Thermal media, do NOT load ribbon in the printer.See Determining Thermal
Media Types on page 371.
• To avoid ribbon wrinkling and other print problems, always use an empty ribbon core that matches your
transfer ribbon roll’s inner diameter (I.D.).
Your printer requires ribbons manufactured by Zebra that have a ribbon-out trailer (reflector). When the
printer senses this trailer, it recognizes that the transfer ribbon roll has been used up and it stops printing.
In addition, ribbons and ribbon cores manufactured by Zebra include notches to help maintain ribbon-roll
engagement and drive (without slipping) while printing.
Zebra-manufactured ribbons for your printer include:
• Performance Wax
• Premium Wax/Resin
• Performance Resin for synthetics (6 inches per second or ips maximum speed) and coated paper (4 ips
maximum speed)
• Premium Resin for synthetics (4 ips maximum speed)
IMPORTANT: If using74-meter ribbons, DO NOT pair them with early-model desktop printer
ribbon cores! These older cores are too large. You can identify the older-style ribbon cores (and
some Non-Zebra ribbons) by notches seen ONLY on one side of the ribbon core.
IMPORTANT: DO NOT use ribbon cores that have damaged notches (rounded, frayed, smashed,
etc.) The core notches must be square to lock the core onto the spindle. Otherwise, the core may
slip and cause ribbon wrinkle, poor end-of-ribbon sensing, or other intermittent failures.
187
Setup
Loading Zebra Transfer Roll Ribbon
Be sure to complete the preparatory steps described here before you load the ribbon.
Prepare the ribbon by removing its wrapping and pulling its adhesive strip free.

4. Attach the ribbon to the take-up core. Use the adhesive strip on new rolls; otherwise, use a thin strip of
tape. Align the ribbon so that it will be taken straight onto the core.
5. Turn the ribbon take-up hub with the top moving toward rear to remove slack from the ribbon. Rotate
the hub to finish aligning the take-up ribbon position to the ribbon supply roll. The ribbon leader should
be completely covered by the ribbon.
6. Verify that media is loaded correctly and is ready for printing, then close the printer cover.
7. If printer power is ON, press FEED to advance the media a minimum of 20 cm (8 in.) tostraighten the
ribbon and remove any slack and ribbon wrinkle and align the ribbon on the spindles.
8. Change the print mode setting from DIRECT THERMAL to THERMAL TRANSFERusing the printer driver,

Loading Non-Zebra 300-Meter Transfer Ribbon
To load non-Zebra 300-meter transfer ribbon onto your printer, you will need Zebra ribbon core adapters.
The minimum requirements to use non-Zebra 300-meter ribbons with your printer are as follows:
Inside core diameter (I.D.) 25.4 mm (1.0 in., with a range of 1.004 in. to 1.016 in.)
Inside core material Fiberboard (hard materials such as plastic cores may NOT function
correctly)
Ribbon width range 33 mm to110 mm(1.3 in. to4.3 in.)
Ribbon's maximum outer
diameter (O.D.)
66 mm (2.6 in.)
CAUTION—PRODUCT DAMAGE: Using non-Zebra media or ribbons not approved for use in
your Zebra printer may damage your printer or printhead. Image quality may also be affected by:
• poor or marginal ribbon performance (maximum print speed, ink formulation, etc.)
• core material that is too soft or too hard)
• loose or tight ribbon core fit or a ribbon core that exceeds the maximum outer diameter of 66 mm)
The adapters help you align the ribbon and core to the media (and printer’s) center. They include a core-
lock spring to engage the soft fiberboard inside the ribbon core. They scale, as measured from the printer’s
center-line, when mounted in the printer.

Setup
3. Press and hold PAUSE and CANCEL simultaneously for two seconds, then release.
The printer feeds and measures a few labels and adjusts media sensing levels.When it completes
measuring, the STATUS indicator lights solid Green.
NOTE: After initial calibration to a specific media, additional calibrations are not necessary
for newly-loaded media as long as it is of the same type as the prior media used (media type,
vendor, batch, size, etc.). The printer automatically measures the newly-loaded media and adjusts
for any small changes in its characteristicswhen printing.
After you load a roll of new media from the same batch, you can simply press FEED (Advance)
once or twice to synchronize the labels and get the media set for printing.
NOTE: If the printer should fail to recognize and correctly calibrate to the media, see Manually
Calibrating Media on page 336.
Test Printing with a Configuration Report
Before connecting the printer to a computer, make sure that the printer is in working order by printing a
configuration report.
The information in the configuration reports may come in handy during printer installation and
troubleshooting.
1. Make sure the media (and ribbon, if you printing on thermal transfer media) are loaded properly in the
printer and the printer's top cover is closed.
2. Turn printer power ON.
3. Afterthe printer enters ready state (the STATUS indicator lights solid green), press and hold FEED and
CANCEL simultaneously for two seconds, then release.
The printer and network configuration reports print.When the printer stops printing the reports, the
STATUS indicator turns solid green.
200

If you cannot get these reports to print, see Troubleshooting on page 311.
Detecting and Recovering from a Media-Out Condition
When you run out of media, your printer reports a Media Out condition. The STATUS Indicator flashes red
and the SUPPLIES indicator light up red. This is part of the normal media usage cycle.
To recovery from a Media Out condition:
1. Open the printer.
NOTE: During the Media Out alert condition, the media is usually at the end of the roll or
nearly at the end of the roll, with a label missing from the liner.
201
Setup
2. Remove the remaining media and roll core.
3. Insert a new roll of media.
If you are installing more of the same media... Load the new media and press FEED (Advance)
one time to resume printing.
If the new media you have loaded is NOT the
same as the prior media used with this printer
(different size or length, or from a different
vendor or batch)...
Load the new media and use the SmartCal
procedure to calibrate the printer to the new
media to ensure optimal print results.
NOTE: If you loadmedia of a different size (length or width), you will usually need to change
the programmed media dimensions or the active label format by adjusting the printer settings
using the menu or through printer programming commands..
IMPORTANT: At times a label may be missing somewhere in the middle of your roll of labels
instead of at the end of the media roll. This may cause the printer to issue a Media Out alert. To
recover from this alert condition:
1. Pull the media past the missing label until the next label is over the platen roller.
2. Close the printer.
202
3. Press FEED (Advance) once.
The printer resynchronizes the label position and readies to continue printing.
Setup
Detecting and Recovering from a Ribbon-Out Condition
When the printer runs out of ribbon, it alerts you of the condition. This is part of the normal printing cycle.
Use these steps to replace the ribbon and continue printing.
1. Open the printer.
NOTE: Typically, in the ribbon-out-condition, the reflective ribbon—which the printer uses to
detect an end-of-ribbon condition—is exposed on the underside of the ribbon cartridge or
ribbon roll. The front ribbon/top roll is also full.
2. Remove the used ribbon roll or ribbon cartridge from the take-up spindlesand dispose of it
properly.Keepthe empty ribbon core (roll) so you can use it to load the new ribbon roll.
3. Load a new ribbon roll (or insert a new ribbon cartridge if the printer is a ribbon cartridge model).
4. Press FEED (Advance) once to resume printing.

Setup
Interface Cable Requirements
Data cables must be of fully-shielded construction and fitted with metal or metalized connector shells.
Shielded cables and connectors are required to prevent radiation and reception of electrical noise.
To minimize electrical noise pickup in the cable:
• Keep data cables as short as possible (1.83 m [6 ft.] recommended).
• Do NOT tightly bundle the data cables with power cords.
• Do NOT tie the data cables to power wire conduits.
IMPORTANT: This printer complies with FCC Rules and Regulations, Part 15, for Class B
Equipment, using fully-shielded data cables. Use of unshielded cables may increase radiated
emissions above the Class B limits.
USB Interface
Universal Serial Bus (version 2.0 compliant) provides a fast interface that is compatible with your existing
PC hardware. USB’s plug-and-play design simplifies the installation. Multiple printers can share a single
USB port/hub.
When using a USB cable, verify that the cable or cable packaging bears the “Certified USB™” mark (see
below) to guarantee USB 2.0 compliance.
Serial Interface
The printer uses a Null Modem (cross-over) cable for DTE communications. The required cable must have a
nine-pin D-type (DB-9P) male connector on one end which plugs into the mating (DB-9S) serial port located
on the back of the printer. The other end of this signal interface cable connects to a serial port on the host
computer. See Interface Connector Wiring in this guide for pinout information.
205
Setup
The serial port communication settings between the printer and host (typically a PC) must match for reliable
communication. The Bits per second (or Baud rate) and Flow control are the most common settings that get
changed.
Serial communications between the printer and the host computer can be set by:
• ZPL ^SC command.
• resetting the printer to its default printer configuration.
Factory defaults for serial communication settings are:
• 9600 baud
• 8 bit word length
• NO parity
• 1 stop bit
• XON/XOFF
• ‘Software’ data flow control in Windows-based host systems
IMPORTANT: Do not use RS-232 cable adapter dongles (DTE<=>DCE) with this printer. Some
dongles can interfere with the operation of USB host port devices at printer power-up.
Ethernet (LAN, RJ-45)
Your printer requires UTP RJ-45 Ethernet cable rated CAT-5 or better.
Your printer must be physically connected to your Ethernet / LAN network using the appropriate cable and
be configured properly to make a network connection and operate on your network.
The printer includes an in-built network print server whichcan be accessed through the printer’s print
server web pages.
206

Assigning an IP Address for Network Access
All devices on an Ethernet network (LAN and WLAN) including your printer require a network IP (Internet
Protocol) address.
You will need the printer’s IP address to access the device for printer configuration and for printing.
There arefive ways to assign an IP address:
• DHCP (Dynamic Host Configuration Protocol) (default setting)
• Zebra Setup Utilities (includes the ZebraDesigner Windows printer driver)
• Telnet
• Mobile Apps
207
• ZebraNet Bridge.
Setup
DHCP for Personal Networks
Your printer is set to operate on an Ethernet LAN or Wi-Fi network with DHCP by default.
This setting is intended primarily for personal networks. The network automatically provides a new network
IP address each time printer power is turned ON.
The Windows printer driver uses a Static IP address to connect to the printer. You must change the IP
address set in the printer driver to access the printer if its assigned IP address has changed after initial
printer installation.
Using Your Printer on a Managed Network
Using the printer in a structured network (LAN or Wi-Fi) requires a network administrator to assign the
printer a Static IP address and establish other settings that your printer needs to operate on the network.
Print Server User ID and Password Defaults
You will need the default User ID and/or default password for the printer's in-built print serverto access
some printer's features and its WiFi option.
Factory default User ID: admin
Factory default Password: 1234

Peel (if you have the Label Dispenser
option installed)
The printer peels the label from the liner while printing.
It pauses to print the next label until the current one is
removed.
Cutter (if you have the Cutter option
which isfactory-installed)
The printer cuts each label after it is printed.
To set the printer to use an available print mode:
• Access the setting for Collection Method. See
Print > Label Position > Collection Method on page 143.
• Use the ^MM command described inthe ZPL Programming Guide. This guide is available for download
from zebra.com/manuals.
Adjusting the Print Quality
Print quality is affected by a combination of the heat (or density) setting of the printhead, print speed, and
the media loaded. Experiment with these settings to find the optimal mix for your application.
You can set print quality using the Configure Print Quality wizard in Zebra Setup Utilities.
Print a print quality report using FEED self-test to print a range of labels that help you identify print
darkness and print speed settings to optimize general print quality and barcode quality. For instructions on
printing this report, see Printing a Print Quality Report(FEED Self Test) on page 327.
Before adjusting any settings, verifythe printer’s media settings by printing a printer configuration report.
See Printing the Printer and Network Configuration Reports (CANCEL Self Test) on page 324.
1. To adjustthe print darkness (or density) setting, use one of these methods:
• Use the Set Darkness (~SD) ZPL command. For details, see the ZPL Programming Guide which you
can download from zebra.com/manuals.
• Try a Manual Print Darkness Adjustment on page 338.
2. To adjust the print speed, use one of these methods:
• application software such as ZebraDesigner which is available for download from zebra.com/
zebradesigner.
• The ZPLPrint Rate (^PR) command.For details, see the ZPL Programming Guide which you can
downloaded from zebra.com/manuals.
NOTE: Media manufacturers may recommend specific speed settings when using your printer
with their media. The recommended speed may be lower than your printer’s maximum speed
setting.
242
Print Operations
3. To reduce the maximum distance for automatic media type detection and sensing, usethe ZPL
Maximum Label Length command (^ML).
The minimum distance should be no less than twice the longest label to be printed. If the largest label
being printed is 2 inches by 6 inches, the maximum label (media) length detection distance can be
reduced from the default distance of 39 inches to 12 inches.
Adjusting the Print Width
You must set the print width before you use the printer for the first time. You must also set it when you load
media into the printer that is of a different width than the one you loaded for the previous print job.
To set the print width, you can use one of the following:
• Windows printer driver
• application software such as ZebraDesignerwhich can be downloaded from zebra.com
• ZPL programming Print Width (^PW) command. See the ZPL Programming Guide available from
zebra.com/manuals for details.)
• For instructions on adjusting the width, see Manual Print Width Adjustment on page 337.
Replacing Supplies while Using the Printer
If the media supply (ribbon, labels, receipts, tags, tickets, etc.) runs out while printing, leave the printer
power ON while reloading. (Data loss occurs if you turn off the printer). After you load a new roll of media
or ribbon, simply press FEED to resume printing.
Printing on Fanfold Media
Use this procedure to print on fanfold media.
Fanfold media enters the printer from the back and exits through the front of the printer during the print
job.
1. Remove media from the printer.
2. If you have thermal transfer printers and it has a fanfold cover installed, remove the cover.
3. Open the top cover of your printer.
243
Print Operations
4. For ZD621 printers and the ZD421 Cartridge printer, adjust the media guide stop position with the gold
thumb wheel.
a) Use a piece of the fanfold media to set the stop position.
b) To make the space between the guides wider,rotate the wheel away from you. To make the space
narrower, rotate the wheel toward you.
244
Print Operations
5. For non-cartridge ZD421 printers—Adjust the media guide stop position with the slide lock on the left
side media guide.
a) Use a piece of the fanfold media to set the stop position.
b) Push the gray lock down towards the base of the media roll holder to secure the roll in position.
c) Rotate the wheel toward you to make the space between the media guides narrower.
245
Print Operations
6. Insert the media through the slot at the rear of the printer, and place the media between the media
guide and roll holders.
7. Close the top cover.
IMPORTANT: The media guide stop position may need further adjustment if, after printing or
after pressing FEED to advance several labels:
• the media does not track down the center (moves from side to side), or
• the sides of the media (liner, tag, paper, etc.) are frayed or damaged when exiting the printer
If additional adjustment does not correct the problem, route the media over the two roll-holding
pins on the media guide.
You can also provide additional support for thin media by placing an empty roll core (of the same
width as the fanfold media stack) between the roll holders.
Printing with Externally-Mounted Roll Media
Your printer accommodates externally-mounted roll media (as it does for fanfold media). It requires a
media-roll-and-stand combination to ensure low (initial) inertia when pulling the media off the roll.
Make note of these considerations when using externally-mounted roll media:
• The media should ideally enter the printer from directly behind the printer and pass through the fanfold
media slot in the rear of the printer.
246
Print Operations
• The media should move smoothly and freely. It should not slip, skip, jerk, bind and then move, etc. when
mounted on your media stand.
• The movement of the media roll should not be impeded by contact withany printer or other surfaces.
• The printer should be placed such that it may not slip or lift up away from its operating surface while
printing.
Using the Label Dispenser Option
The label dispenser option allows you to print a label and have the backing material (liner/web)
automatically removed before the label is dispensed. If you are printing multiple labels and the printer
has been programmed appropriately, the printer prints and dispenses the next label after you remove an
already printed anddispensed, peeled label.
To use label dispense mode, use the Windows printer driver—or the Configure Printer Settings wizard in
Zebra Setup Utilities—to set the printer's Media Handling setting to Peel-Off.
You can also configure the printer to dispense labels by sending it programming commands.If using ZPL,
use these command sequences:
• ^XA ^MMP ^XZ
• ^XA ^JUS ^XZ
1. Load the labels into the printer. Close the printer and press FEED until a minimum of 100 mm (4 in.) of
exposed labels exit the printer. Leave the labels on the liner.
247
Print Operations
2. Lift the liner over the top of the printer, then open the door by pulling the gold latch in the center of
dispenser door away from the printer.
248
Print Operations
3. Insert the label liner between the dispenser door and the printer body.
4. Close the dispenser door while pulling the end of the label liner tight.
249
Print Operations
5. Press and release FEED (Advance) one or more times until a label is presented for removal.
6. During the print job, the printer will peel off the backing and present a single label. Take the label from
the printer to allow the printer to print the next label.
NOTE: If you did not activate the label-taken sensor—using printer programming commands
—to detect the removal of the dispensed (peeled) label, the printed labels will stack and may
bind the mechanism.
Using the Linerless Options
The Linerless Media Tear-Off and Cutter options operate much like the standard media printers. These
options include an additional sensor to detect when a printed and presented label is taken from the printer.
Linerless printers require special cleaning processes to maximize the platen (drive) roller and special non-
stick surfaces in the printer and media path areas.
The Linerless printing option allows you to print a multi-label format/form that stops between each label.
Removing the dispensed (peeled) label triggers the printer to print and dispense the next label until all
labels have been printed.
To use dispense mode, set MEDIA HANDLING to PEEL-OFF in the printer driver or with the Zebra Setup
Utilities using the Configure Printer Settings wizard.
Alternatively, send the appropriate ZPL programming commands to the printer.When programming in ZPL,
you can use the command sequences shown below to configure the printer to use the dispenser option:
• ^XA ^MMP ^XZ
• ^XA ^JUS ^XZ
250
For details, see the ZPL Programming Guide available for download from zebra.com/manuals.
Print Operations
Linerless Printing
Linerless media loads the same as models with the standard tear-off bezel or the general factory-installed
cutter options.
For information on loading the media. see
Loading Media on page 179 and Loading Roll Media for Cutter
Models on page 185.
• Media Reloading—Clean the printhead and inspect the media path and platen roller for build up of
adhesive and debris. Remove particles with the adhesive side of your linerless media. Lightly touch
the media path and platen roller with the label to lift particles off the exposed area of the platen roller
and the media path areas. For more information, see the Linerless Platen (Drive) Roller entry in the
Recommended Cleaning Schedule on page 271.
• Do not remove new media from it’s protective wrapping until you are ready to place it in the printer.
Setting the roll on its side will pick up contaminants and may stick to surfaces.
IMPORTANT: The platen roller can accumulate adhesive on the outer edges of the roller. After
using many rolls of media, these rings of adhesive may dislodge as the printer is used routinely.
These particle clumps can transfer to other areas. Clean the platen as needed to remove this
build-up. using the instructions in the Maintenance section of this guide.
Sending Files to the Printer
Graphics, fonts and programming files can be sent to the printer from supported Microsoft Windows
operating systems using Link-OS Profile Manager, Zebra Setup Utilities (and driver), ZebraNet Bridge or
Zebra ZDownloader available from the Zebra website at zebra.com/software.
Ribbon Cartridge Programming Commands
The Ribbon Cartridge printer available with this Zebra printer series offers several Set-Get-Do (SGD)
programming commands to support the use of the ribbon cartridge.
See the ZPL Programmer’s Guide for more details on SGD commands and, in particular, SGD ribbon
cartridge commands.The guide can be downloaded from zebra.com/manuals.
The following are examples of SGD ribbon cartridge commands.
! U1 getvar "device.feature.ribbon_cartridge"

You can use Zebra Setup Utilities to send commands and receive status from the printer using the Open
Communication With Printer feature.
Printing with the Attached Battery Base and Battery Option
Printer operating procedures change slightly when using the battery. Power connections and power
loss scenarios necessitate the differences in operation. The battery is designed to maximize battery life,
maintain print quality, and have simple operation.
• When you connect the printer’s external power supply to the battery, it 'wakes up' anddetermines if it
needs charging (charge level below 90%).
• The battery will not start charging until the battery’s charge drops below 90% charge. This charging
design extends your battery’s life.
• After the battery begins charging, the battery will charge to 100% capacity and then enter Sleep Mode.
• The printer receives external power that passes through the battery circuitry to the printer. The battery
does not charge when the printer is printing or moving media.
• The battery uses only a very minimal power during Sleep Mode to maximize the available charge that it
stores.
• It takes about two hours to charge a fully-discharged battery.
Uninterrupted Power Supply (UPS) Mode
In UPS mode, the printer receives external power which passes through the battery circuitry to the printer.
1. Press Battery Control to ‘wake up’ the battery and check the battery has charge.
After 60 seconds, the battery enters sleep mode. In this mode, the battery uses loss of external power
as a cue to wake up and supply the printer with power.
2. Turn printer power OFF and ON as you normally would.The printer does not require the battery be
manually turned on to operate when it in UPS mode.
Battery Mode
In this mode, the printer is powered solely by the battery.
1. Press Battery Control on the attached battery to wake up the battery and check if the battery has
sufficient charge. After 60 seconds, the battery goes to sleep if the printer is OFF.
2. Turn printer power ON.
3. Use the printer as you normally would.
4. Check the battery charge status when needed by pressing Battery Control.
5. Change or charge your battery when the last battery charge level indicator is flashing.
NOTE: Print operation may be interrupted if the battery charge is used up and the printer
turns off.
252
Print Operations
Printer Fonts
The ZD Series printer supports multiple languages and fonts.
You can avail of advanced font mapping and scaling technology available with your printer using the ZPL
programming language. ZPL commands support the following:
• Outline fonts (TrueType and OpenType)
• Unicode character mapping
• Basic bitmapped fonts
• Character code pages
The font capabilities of your printer are programming-language dependent.
• For descriptions and documentation of the fonts, code pages, character access, listing fonts, and
limitations for their respective printer programming languages,see the ZPL and the legacy EPL
programming guides downloadable from
zebra.com/manuals.
• For information on text, fonts and character support, see the printer programming guides.
Zebra has variety of utilities and application softwareto enable font downloads to the printer for the ZPL
and EPL printer programming languages.
IMPORTANT: Some ZPL fonts that are factory-installed in your printer are license-restricted. They
CANNOT be copied, cloned, or restored to your printer by reloading or updating the firmware.If
these license-restricted ZPL fonts are removed using an explicit ZPL object delete command, you
will need to repurchase and reinstall them using a font activation and installation utility.
EPL fonts do not have this restriction.
Identifying Fonts in Your Printer
Fonts can be loaded into various storage locations in the printer.Fonts and memory are shared by the
programming languages in the printer.
The ZPL programming language can recognize EPL and ZPL fonts. However, EPL programming can only
recognize EPL fonts. See the respective programming guides for more information on fonts and printer
memory.
Specific to ZPL fonts:
To manage and
download fonts for ZPL
print operation
Use the Zebra Setup Utility or ZebraNet Bridge Utilities.
To display all fonts
loaded onto your printer
Send the printer the ^WD ZPL commandto the printer. See the ZPL
Programming Guide for details.
In ZPL:
• The bitmap fonts in the various printer memory areas are identifiable by
the .FNT file extension.
• The scalable fonts are identified with the .TTF, .TTE or .OTF file
extensions. (EPL does not support these fonts.)
253
Print Operations
Localizing the Printer with Code Pages
For each printer programming language, ZPL and EPL, your printer supports two sets of language, region
and character sets for the permanent fonts loaded onto the printer.
Your printer supports localization with common international character map code pages.
For ZPL code page support, including Unicode, see the ^CI command in the ZPL Programming Guide.
Asian Fonts and Other Large Font Sets
Both of the printer’s programming languages, ZPL and EPL, support the large pictographic double-byte
character Asian font sets.The ZPL programming language supports Unicode.
Asian language ideographic and pictographic fonts have large character sets with thousands of
characters that support single language code page.Tosupport for these large character sets, printer
manufacturers adopted a double-byte (67840 maximum) character system (instead of the single-byte, 256-
maximumcharacter system used by Latin-based language characters to address this issue).
With the invention of Unicode came the ability tosupport multiple languages using a single font set. A
Unicode font supports one or more code points (relate these to code page character maps) accessed in a
standard method that resolves character mapping conflicts.
The number of fonts that can be downloaded to your printer is dependent upon the amount of available
Flash memory not already in use and the size of the font to be downloaded.
NOTE: Some Unicode fonts are large-sized. These include MS (Microsoft) Arial Unicode font (23
MB) available from Microsoft and the Andale font (22 MB) offered by Zebra. These large font sets
typically support a large number of languages.
Procuring and Installing Asian Fonts
Asian bitmap font sets are typically downloaded into the printer either by the printer user or an integrator.
ZPL fonts are purchased separately from the printer.
The following EPL Asian Fonts are available as free downloads from zebra.com:
• Simplified and Traditional Chinese (The SimSun scalable Simplified Chinese font is pre-loaded onto
printers that ship with a power cord designed for use in China.)
• Japanese (JIS and Shift-JIS mappings)
• Korean including Johab
• Thai
EPL Line Mode– Direct Thermal Printers only
Your direct thermal printer supports Line Mode printing. EPL Line Mode printing is designed to be
command compatible with EPL1 programming language.
Line Mode printing is ideal for basic retail (also referred to as point of sale or POS), shipping, inventory,
work flow control, and general labeling. EPL printers with Line Mode are versatile printers than can print a
wide range media and barcodes.
254
Print Operations
Line mode printing only prints single lines the height of the largest element present in the line of text and
data–barcode, text, a logo or simple vertical lines. Line mode has many limitations due to the single line of
print: no fine element placement, no overlapping elements, and no horizontal (ladder) barcodes.
• To enterLine Mode printer operation, send the printer the EPL OEPL1 command. See the EPL
Programming Guide (Page Mode) or the EPL Line Mode Programming Guide for details.
• Exit Line Mode printer operation by sending the printer the escOEPL2 line mode command. See the
EPL Line Mode Programming Guide for details.
• When Line Mode is active, ZPL and EPL (EPL2) Page Mode programming is processed as Line Mode
programming and data.
• When default ZPL and EPL (EPL2) Page Mode are active, Line Mode programming is processed as ZPL
and/or EPL programming and data.
You can determine and verify the printer programming mode (that the printer is set to) by printing a printer
configuration report.
ZD621 Locking Printer Option
The locking printer option is available only as a healthcare model.
The following features are built into the locking printer:
• Lock and key access to the printer’s media compartment.
• Metal locking mechanism built into the printer.
• Precision fabricated metal parts for repeatable movement.
• The locking mechanism comes with two keys.
• Supports industry recognized Kensington lock slot that allows you to lock printer to any immovable
object such as a desk.
• For added security, includes a permanently-sealed media window (not serviceable).
• The FEED button is disabledon the locking printer models. This is to prevent users from manually
advancing media when the printer is locked. The FEED button will always boot up in FEED disabled
mode.
• Supports only media that can be loaded within the printer. This model is not recommended if you need
to you fanfold media for printing.
For an illustration of the locking printer features, see ZD621 Direct Thermal Locking Printer Feature
(Healthcare Models Only) on page 45.

Print Operations
Zebra Keyboard Display Unit (ZKDU) – Printer Accessory
The ZKDU is a small terminal unit that interfaces with the printer to enable ease of access to EPL or ZPL
label forms stored in the printer.
The ZKDU is used for the following functions:
• List label forms stored in the printer
• Retrieve label forms stored in the printer
• Input variable data
• Printing labels
• Switching between EPL and ZPL to support dual-format printer language format/form types. These
forms can be stored and printed in late model Zebra label printers.
NOTE: The ZKDU is strictly a terminal unit. It does not store data and cannot be used to change
printer or printing parameters.
Zebra Basic Interpreter (ZBI)
Customize and enhance your printer using the ZBI 2.0 programming language. ZBI 2.0 allows Zebra
printers to run applications and take input from scales, scanners and other peripherals without a PC
or network connection. ZBI 2.0 works with the ZPL printer command language so that printers can
understand non-ZPL data streams and convert them into labels. That means the Zebra printer can create
barcodes and text from input received, non-ZPL label formats, sensors, keyboards, and peripherals.
Printers can also be programmed to interact with PC-based database applications to retrieve information
for use on printed labels.
• ZBI 2.0 can be activated by ordering a ZBI 2.0 Key Kit, or activated by purchasing a key from zebra.com.
• Use the ZBI Key Manager (also know as ZDownloader utility) to apply the key.
• An intuitive ZBI-Developer is used to create, test and distribute ZBI 2.0 applications. The built-in virtual
printer allows you to quickly create, test and prepare programs for use.
ZBI-Developer is available on the Zebra web site at zebra.com/software. Look for Zebra Basic Interpreter
2.0.

Setting the Power Failure Recovery Mode Jumper
The printer can be configured to restart itselfunattended and unaidedafter a power failure by setting it to
this mode.
NOTE: Power Failure Recovery Mode is available ONLY on printers with a printer connectivity
module installed.
The printer connectivity modules have a power failure recovery jumper. The jumper is set to OFF by
default. By setting the jumper to ON, you can make the printer automatically Power ON when it is plugged
into an active AC power source (meaning printer power is ON).
NOTE: The discharge of electrostatic energy that accumulates on the surface of the human
body or other surfaces can damage or destroy the printhead or electronic components used in
this device. You must observe static-safe procedures when working with the printhead or the
electronic components.
1. Disconnect the DC power plug and any interface connectors from the rear of the printer.
2. Remove the module access door and connectivity module. See Removing Printer Connectivity Modules
on page 65which includes instructions for ZD421 printers.
NOTE: The module removal steps for ZD621 printers is similar to that for ZD421 printers.
3. Move the AUTO (Power Failure Recovery Mode) jumper from the OFF position to the ON position.
4. Reinstall the connectivity module and module access door. See Installing the Internal Ethernet (LAN)
Module on page 64 or Installing the Serial Port Module on page 63.
NOTE: The procedures for the connectivity module installation are the same for the ZD621
printers as they are for the ZD421 printers.
5. Reconnect the printer DC power plug and interface cables to the printer.

USB Host Port and Link-OS
UsageExamples
USB Host Port and Link-OS UsageExamples
This section has information on using the printer’s USB Host port along with Link-OS features and apps
(applications).Try these example tasks in the sequence provided, so you develop a good understanding of
how to use the USB Host Port.
USB Host
The USB host port allows you to connect USB devices—such as a keyboard, scanner, or USB flash
(memory) drive—to the printer.
Uses for the USB Host are as follows:
• Firmware updates
• File transfers and management
• A port for low power USB data entry devices (keyboards, scales, scanners, and other wedge devices).
258
1 USB host port
IMPORTANT: The USB Flash drive must be formatted using the FAT file system. Filenames can
be 1 to 16 alphanumeric characters (A, a, B, b, C, c, ..., 0, 1, 2, 3, ...) only. Use only ASCII characters.
Do NOT use Asian characters, Cyrillic characters, or accented characters in filenames. Some
functions may not work properly if there are underscores in a filename. Use periods instead.
USB Host Port and Link-OS UsageExamples
Using a USB Host for Firmware Updates
The USB host port allows you to connect an USB Flash drive to the printer to perform firmware updates.
Zebra "mirror" functions enable you to easily accomplish important printer management tasks.
For example, you can update the printer firmware by downloading the latest version from
zebra.com,
copying the files to a USB Flash drive (of up to a 1 TB storage capacity), connecting the USB drive to the
printer, and uploading them to printer memory.
See the printer ZPL Programming Guide for information on the Mirror and Set-Get-Do (usb.mirror) SGD
commands.

Exercise 1: Copy Files to a USB Flash Drive and Perform USB Mirror
1. On your USB flash drive, create the following:
• A folder called Zebra
• In that folder, three subfolders:
• appl
• commands
• files
2. In the /appl folder, place a copy of the latest firmware for your printer.
NOTE: Avoid underscores in the filenames. Some functions may NOT work properly if there
are underscores. Use periods instead.
3. In the /files folder, place the following file: ZEBRA.BMP
4. In the /commands folder, place the following files: SAMPLELABEL.TXT and LOGO.ZPL.
5. Insert the USB flash drive into a USB host port situated on the front of your printer.
6. Observe the user interface and wait for the following:
• If the firmware on the USB flash drive is different than what is on the printer, the firmware downloads
to the printer. The printer then restarts and prints a printer configuration label. (If there is no firmware
on the USB flash drive or if the firmware version is the same, the printer skips this action.)
• The printer downloads the files in the /files folder and briefly shows on the display and, in case
ofprinters that have a Color Touch display, the names of the files that are downloading to the printer
form the USB drive.
• The printer executes any files you added to the /commands folder.
• The printer restarts, then displays the message MIRROR PROCESSING FINISHED.
7. Remove the USB Flash drive from the printer.

Maintenance
Maintenance
This section provides routine cleaning and maintenance procedures. It is recommended that you procure
designed to work with your printer from zebra.com/supplies.
Cleaning
Your Zebra printer may require periodic maintenance to keep it functional and printing high quality labels,
receipts, and tags.
IMPORTANT: The cutter mechanism does NOT require maintenance cleaning. DO NOT clean
the blade or mechanism. The blade has a special coating to resist adhesives and wear.
Using too much alcohol can result in contamination of the electronic components requiring a
much longer drying time before the printer will function properly.
CAUTION—PRODUCT DAMAGE: DO NOT use an air compressor in place of the can of
compressed air. Air compressors have micro-contaminants and particles that can get into the air
system and damage your printer.
CAUTION—EYE INJURY: When using compressed air to clean the sensors, use eye protection to
protect your eyes from flying particles and objects.
Cleaning Supplies
The following printer cleaning supplies are recommended for use with your printer:
These and other printer supplies and cleaning accessories are available from zebra.com/supplies.
Printhead cleaning pens For routine printhead cleaning.
99.7% min. pure isopropyl
alcohol
Use a labeled alcohol dispenser.
NOTE: Never re-moisten cleaning materials used to clean
the printer. Always use clean supplies.
Fiber-free cleaning swabs To clean the media path, guides, and sensors.
Cleaning wipes To clean the media path and interior (for example Kimberly-Clark
Kimwipes)
270
Maintenance
Can of compressed air
CAUTION—PRODUCT DAMAGE: DO NOT use an air
compressor in place of the can of compressed air. Air
compressors have micro-contaminants and particles that
can get into the air system and damage your printer.
IMPORTANT: To avoid product damage and risk of personal injury, followthe precautions
included in each cleaning procedure when cleaning the printer.
Recommended Cleaning Schedule
Cleaning is a routine part of printer maintenance. Be sure to clean your printer and its components using
the schedule listed here.
Component / Area Recommendations
Printhead Clean the printhead after printing every five rolls of media printed. See
Cleaning the Printhead on page 272.
Standard platen (drive)
roller
As needed to improve print quality. Platen rollers can slip causing print image
distortion and in worst case scenarios not move the media (labels, receipts,
tags, etc.) Usethe detailed instructions in this Maintenance section to clean
and, if necessary, replace the platen.
Standard platen rollers come in two colors, black (203 dpi) and gray (300 dpi).
Linerless Platen (Drive)
Roller
The linerless platen normally does not require cleaning. The adhesive side of
the media picks up particles as you print. Clean if you observe a build-up of
particles on the platen roller.
The platen roller can accumulate adhesive on the outer edges of the roller.
After using many rolls of media, these ‘rings’ of adhesive can get dislodged
when using the printer. These particle clumps can then get transferred
to other areas in the printer, most importantly, the printhead.To remove
adhesive particles, use the adhesive side of a piece of linerless media to
gently press and remove the particles from the plater roller.Seethe
instructions in this Maintenance section for information on cleaning and
replacing the platen.
If the linerless media is sticking and binding in the printer, the silicon non-stick
coating may have been used up. In this case, the linerless platen normally
needs to be replaced.
Linerless platen rollers come in two colors, reddish-brown (203 dpi) and
brown (300 dpi).
CAUTION: Cleaning the roller with solutions or rubbing the delicate
surface of this type of roller will permanently damage or shorten the
usable life of the linerless platen.
Media path Clean thoroughly as neededwith fiber-free cleaning swabs and cloths
moistened with 99.7% pure isopropyl alcohol. Let the alcohol evaporate
completely. See Cleaning the Media Path on page 276.
271
Maintenance
Component / Area Recommendations
Interior Clean as needed usinga soft cloth, brush or compressed air to wipe or blow
dust and particles out of the printer.
Use 99.7% pure isopropyl alcohol and a fiber-free cleaning cloth to dissolve
contaminants like oils and grime.
Exterior Clean as needed using asoft cloth, brush, or compressed air to wipe or blow
dust and particles out of the printer.
The exterior of the printer can be cleaned using plain soap and water
solutions to moisten the cloth. Only use the minimum amount of cleaning
solution to avoid getting solution in the printer or other areas. Do NOT clean
connectors or interior of the printer with this method.
The latest healthcare printer models now include ultraviolet (UV) and
disinfectant-ready plastics for hospital and other similar environments. The
printer user interface controls are sealed so they can be cleaned with the
rest of the printer’s exterior. See the Guide To Disinfecting and Cleaning
Zebra Healthcare Printers on the Zebra website at zebra.com/support for the
latest information on tested and approved cleaning materials and cleaning
methods.
Label dispenser option Clean as needed to improve label dispenser operations.
For details on operating the dispenser, see Cleaning the Label Dispenser
Option on page 280.
Cutter option The cutter is not a user-serviceable component.
Do NOT clean inside the cutter opening or blade mechanism.
Use the exterior cleaning procedure to clean the cutter bezel (housing).
For cleaning and maintenance of this option, call a service technician.
CAUTION: There are no operator serviceable parts in the cutter
unit. Never remove the cutter cover (bezel). Never attempt to insert
objects or fingers in to the cutter mechanism.
IMPORTANT: The blade has a special coating to resist adhesives
and wear. Cleaning it may ruin the blade.
IMPORTANT: Use the recommended cleaning supplies listed in this
guide.Using unapproved tools, cotton swabs, solvents (including
alcohol), etc. may damage or shorten the cutter’s usable life or
cause the cutter to bind.
Cleaning the Printhead
For optimal print operations, clean the printhead each time you load a new roll of media.
Always use a new cleaning pen on the printhead. Old, used cleaning pens carry contaminants from
previous use that may damage the printhead.
CAUTION: The printhead becomes hot while printing. To protect from damaging the printhead
and risk of personal injury, avoid touching the printhead. Only use the cleaning pen to perform
printhead maintenance.
272
Maintenance
CAUTION—ESD: Observe static-safe procedures when working with the printhead or the
electronic components under the top cover. The discharge of electrostatic energy that
accumulates on the surface of the human body or other surfaces can damage or destroy the

This section provides a variety of tools and utilities built into the printer. They are designed to assist you
with setup, configuration, and debugging (printer and command programming).
Printer Diagnostics
A variety of diagnostic tools and procedures are available to help you operate your printer and diagnose
problems. These include printer configuration and network configuration reports, diagnosticreports,
calibration procedures, and the ability to restore the printer settings to their factory defaults if needed.
Diagnostic Testing Tips
IMPORTANT: When performing self-tests, use full-width media. If the media is not wide enough,
the test labels may print on the platen (drive) roller.
To initiate a printer self test, you will need to press a specific user interface button or a combination of
buttons while turning printer power ON. Keep the button(s) pressed until the first indicator light turns off.
The selected self test automatically starts at the end of the normal power-up operation.
• When performing these self tests, do NOT send data to the printer from the central device.
• If your media is shorter than the label to be printed, the test label continues on the next label.
• If canceling a self test before it completes, always reset the printer by turning printer power OFF and
then ON.
• If the printer is dispensing the printer reports and liner is being taken up by the applicator, manually
remove the reports as they become available.
Power-On Self Test
The printer performs a Power-On Self Test (POST) each time printer power is turned ON.
During the Power-On Self Test, the control panel indicators turn on and off as the printer ensures readiness
to operate and handle print jobs.
At the end of this self test, only the STATUS indicator remains lit.
323
Tools
Running a SmartCal Media Calibration
The printer must set media parameters for optimal operation prior to printing. To do this, it automatically
determines the media type (web/gap, black mark/notch, or continuous) and the measure media
characteristics for printing.
1. Make sure media is loaded (and also ribbon if you are using thermal transfer mode) properly in the
printer and the top cover of the printer is closed.
2. Press POWER to turn printer power on and waituntil the printer is in the Ready state .
The STATUS Indicator lights solid green
3. Press and hold PAUSE and CANCEL simultaneously for two seconds, then release.
The printer feeds and measures a few labels and adjusts media sensing levels.When it completes
measuring, the STATUS indicator lights solid Green.
NOTE: After initial calibration to a specific media, additional calibrations are not necessary
for newly-loaded media as long as it is of the same type as the prior media used (media type,
vendor, batch, size, etc.). The printer automatically measures the newly-loaded media and adjusts
for any small changes in its characteristicswhen printing.
After you load a roll of new media from the same batch, you can simply press FEED (Advance)
once or twice to synchronize the labels and get the media set for printing.
NOTE: If the printer should fail to recognize and correctly calibrate to the media, see Manually
Calibrating Media on page 336.
Printing the Printer and Network Configuration Reports (CANCEL Self Test)
To print the configuration report:
324
1. Make sure media is loaded, the printer cover is closed, and printer power is ON.
If printer power is OFF, press and hold CANCEL while turning printer power ON, until the STATUS
indicator is the only indicator lit.

Network (and Bluetooth) Configuration Report
ZD Series printers that have wired or wireless connectivity options installed will print a network
configuration report in addition to a printer configuration report during a CANCEL self-test.
You will need the information in this report to establish and troubleshoot Ethernet (LAN and WLAN),
Bluetooth 4.1 and Bluetooth LE network printing.
In addition to the CANCEL self test, you can also output this report by sending the ~WL ZPL command to
the printer.
The report shown below is an example. The contents of the report may vary for your printer model.
1 iOS Support Setting
iOS devices have Bluetooth Classic 4.X (with 3.0 compatibility). When the Wi-Fi and Bluetooth Classic
wireless connectivity option is installed in your printer, it is listed as supported at the end of the Network

Tools
Printing a Print Quality Report(FEED Self Test)
Different types of media may require different darkness settings. Use this simple but effective method for
determining the ideal darkness for printing barcodes that are within specifications.
During the FEED self test, the printer prints a series of labels at different darkness settings at two different
print speeds.The barcodes on these labels may be ANSI-graded to show print quality.
During this test, one set of labels is printed at low speed, and another set is printed at the high speed. The
darkness value starts at three settings lower than the printer’s current darkness value (relative darkness
of -3) and increase until the darkness is three settings higher than the current darkness value (relative
darkness of +3).
Each label shows the relative darkness and the print speed.
Figure 8Print Quality Report
327
Tools
The speed at which labels are printed during this print quality test depends on the dot density of the
printhead.
• 300 dpi printers: Prints 7 labels at 51mm/sec (2 ips) and 102 mm/sec (4 ips) print speeds
• 203 dpi printers: Prints 7 labels at 51mm/sec (2 ips) and 152 mm/sec (6 ips) print speeds

Tools
Sensor Profile
Use the sensor profile image—which typically prints across several labels or tags—for diagnostics if the
printer is not accurately sensing gaps between labels, if it incorrectly identifies pre-printed areas on a label
as gaps, or cannot detect ribbon.
With the printer in the Ready state, print a sensor profile in one of these ways:
• Using the printer buttons— Turn printer power OFF, then turn printer power ON while holding down
FEED and CANCEL simultaneously. Continue pressing these buttons until the Status indicator is the
only indicator lit.
• Using ZPL— Send a ~JG command to the printer. See the ZPL Programming Guide for more
information on this command. The guide is available for download from
zebra.com/manuals.
Compare your results to the examples shown in Performing a Communication Diagnostics Test on page
334. If sensor sensitivity must be adjusted, calibrate the printer. See Manually Calibrating Media on page
336.

5 Lines between the spikes (indicate where labels are located)
335
Tools
Compare the sensor profile printout to a length of one media form (ex., a label). The spikes should be the
same distance apart as the gaps are on the media.
NOTE: If the gap distances are not the same, the printer is having difficulty determining where
the gaps are located.Try calibrating the printer to the media that is loaded.
Activating Advanced Mode
UseAdvanced mode to access the printer's manual adjustment modes.
1. Ensure media is loaded and printer power is turned ON.
2.
Press PAUSE (
)for two seconds.
All indicators flash yellow.The Status indicator ( ) lights solid yellow, indicating Manual Media
Calibration mode is selected.
3.
To sequentially cycle through the available modes, press FEED (
).
4.
To activate the selected mode, press PAUSE (
).
5.
To exit Advanced mode, press CANCEL (
).
Manually Calibrating Media
Use these steps to manually calibrate the printer for the loaded media.
This Advanced mode is typically used to calibrate the printer to media that is not correctly recognized
during SmartCal media calibration.
You may have to perform manual calibration several times. This involves moving the media sensor each
time until the printer completes the calibration process and returns to ready state.
To manually calibrate the printer to the media:
1. Place the printer in Advanced Mode (see Activating Advanced Mode) and press PAUSE
(
)while the Status indicator ( ) is lit yellow.
The Supplies indicator (
) flashes yellow, after which the Pause indicator ( ) flashes.
336
Tools
2. Open the printer and verify the media sensor is in the center position for label/gap (transmissive)
sensing.
1 Sensor alignment key
2 Alignment arrow (default position)
NOTE: For black-mark or notch media, set the media sensor to the proper location to sense
the mark or notch.
For pre-printed media with print located on the front of the label or on the back of the liner,
position the sensor to a place where it will minimally sense/encounter the pre-print.
3. Remove 80 mm (3 in.) of labels from the liner, then place the label-free area of the liner over the platen
(drive) roller such that the leading edge of the first label is under the media guides.
4.
Close the printer and press PAUSE (
) one time.
The Media indicator (
) flashes while the printer measures the media liner. When complete, the Pause
indicator (
) begins to flash.
5. Open the printer and reposition the media to locate a label directly above the movable sensor.
6. Close the printer.
7.
Press PAUSE (
) one time.
The printer feeds and measures several labels. If it is able to determine the correct media type (gap, black
mark,or notch) and measure the media length, it returns to Ready state.
Manual Print Width Adjustment
You can manually adjust the print width for your printer depending on your printing needs.
Place the printer in Advanced mode. See Activating Advanced Mode on page 336. Then press PAUSE
(
) while the Pause indicator ( ) lights up yellow.
The printer prints a 16 mm (0.63 in.) box, pauses momentarily, prints a slightly larger box, pauses again, and
so on.
When you see the printer print a box that matches the width of your media, press FEED (
) to select that
print width and return the printer to Ready state for printing.
337
Tools
To return to the maximum print width setting,allow the printer to proceed until it reaches that width without
pressing FEED (
).
Manual Print Darkness Adjustment
To initiate aManual Print Darkness Adjustment,press PAUSE (
) while the data indicator ( ) is lit yellow.
The printer prints a test pattern showing the current darkness number and several barcode patterns and
pauses momentarily. Itrepeats the pattern with the next darkness level and the next.

Media
Media
This section provides a simple media overview for your printer.
Types of Thermal Media
IMPORTANT: Zebra strongly recommends the use of Zebra-brand supplies in order to ensure
consistent high-quality printing. A wide range of paper, polypropylene, polyester, and vinyl
stock has been specifically engineered to enhance the printing capabilities of the printer and to
prevent premature printhead wear.
To purchase supplies, go to zebra.com/supplies.
Your printer can use various types of media:
• Standard media—Most standard (non-continuous) media uses an adhesive backing that sticks individual
labels or a continuous length of labels to a liner.
• Continuous roll media—Most continuous roll media is direct thermal media (similar to fax paper) and is
used for receipt or ticket style printing.
• Tag stock—Tags are usually made from a heavy paper (up to 0.19mm or0.0075 in.thick). Tag stock
does not have adhesive or a liner, and it is typically perforated between tags.
Whereas roll media is the most common type of media used, your printer can also use continuous media
and fanfold media.
NOTE: The locking printer models can handle only media that is loadable within the printer's
media compartment. They are not recommended for fanfold media printing.
Determining Thermal Media Types
Thermal transfer media requires ribbon for printing while direct thermal media does not. To determine if
ribbon must be used with a particular media, perform a media scratch test.
To perform a media scratch test,scratch the print surface of the media with a fingernail or pen cap. Press
firmly and quickly while dragging it across the media surface.
NOTE: Direct thermal media is chemically treated to print (expose) when heat is applied. This
method of testing the media uses friction heat to help identify the media.
Did a black mark appear on the media?

ZPL Configuration
ZPL Configuration
This section provides an overview of managing printer configuration, the Configuring Status Report, and
Printer and Memory Printouts.
Managing the ZPL Printer Configuration
The ZPL printer is designed to allow you to change printer settings dynamically for fast first label out
printing. Printer parameters that are persistent will be retained for future formats to use. Those settings will
remain in effect until they are changed by subsequent commands, the printer is reset, power is cycled, or
when you restore a parameter that has a factory default by resetting the printer to its factory defaults.
The ZPL Configuration Update command ^JU saves and restores printer configurations to initialize (or re-
initialize) the printer with pre-configured settings.
• To keep settings after a power cycle or printer reset, a ^JUS can be sent to the printer to save all
current persistent settings.
• The values are recalled with a ^JUR command to restore the last saved values to the printer.
ZPL stores all parameters at once with a single command mentioned above. The legacy EPL programming
language (supported by this printer) changes and saves individual commands immediately. Most printer
settings are shared between ZPL and EPL. For example, changing the speed setting with EPL will also
change the speed set for ZPL operations. The changed EPL setting will persist even after a power cycle or
reset issued by either printer language.
You can print a printer configuration report to determine the printer settings. It lists operating parameters,
sensor settings and printer status. For instructions on printing the report, see Printing the Printer and
Network Configuration Reports (CANCEL Self Test) on page 324. You can also use the Zebra Setup Utilities
and the ZebraDesigner Windows driver to print this report and other printer reports to help you manage
your printer.
ZPL Printer Configuration Format and Reusable Files
To set up and manage multiple printers that need the same configuration, create a printer configuration
programming file to download to all of them. The other option is to use ZebraNet Bridge to clone many
printers with the same file that you used to configure one printer.
For information on creating a programming file to send to one or more printers, see the ZPL programmer’s
guide and the Configuration Setting to Command Cross-reference on page 378. You can useWindows
Notepad as the text editor to create programming files and Zebra Setup Utilities to send these files to the
printer(s).

The printer can set a command or a group of commands at one (1) time for all receipts or labels that follow.
Those settings remain in effect until:
• they are changed by subsequent commands
• the printer is reset, or
• you restore the printer to its factory defaults.
Printer Memory Management and Related Status Reports
The printer has various memory resources and storage for building and printing.
To help you manage printer resources, the printer supports a variety of format commands. You can use
these commands to manage memory, transfer objects (between memory areas and import / export files),
name object nams, test printer functions, and generate printer operating status reports. They are very
similar to the old DOS commands such as DIR (directory listing) and DEL (delete file). The most common
reports are also part of the Zebra Setup Utility and ZebraDesigner Windows driver.
It is recommended that a single command be processed within this type of format (form). A single
command is easily reused as a maintenance and development tool.
Command Description
^XA Start Format Command
Put your commands
here
Use a single command to manage the printer, test functions, and reports.
Table 16Printer Management and Format Program Structure
381
ZPL Configuration
Command Description
^XZ End Format Command
Table 16Printer Management and Format Program Structure(Continued)
Many of the commands that transfer objects, manage, and report on memory are Control (~) commands.
They do not need the be within a format (form). They will be processed immediately upon receipt by the
printer whether in a format (form) or not.
ZPL Programming for Memory Management
Programming for memory management andfile naming is outlined here.
ZPL has various printer memory locations that are used to run the printer, assemble the print image, store
formats (forms), graphics, fonts, and configuration settings.
The printer file naming requirements as as follows:
• ZPL treats formats (forms), fonts, and graphics like files; and memory locations like disk drives in the
DOS operating system environment:
• Memory Object Naming: Up to 16 alphanumeric characters followed by a three alphanumeric
character file extension, for example, 123456789ABCDEF.TTF.
• Legacy ZPL printers with v60.13 firmware and earlier can only use the 8.3 filename format versus
today’s 16.3 filename format.
• Allows moving objects between memory locations and deleting objects.
• Supports DOS-directory-style file list reports as printouts or status to the host.
• Allows use of wildcards (*) iwhen accessing files.
Command Name Description
^WD Print Directory Label Prints a list of objects and resident barcodes and fonts
in all addressable memory locations.
~WC Print Configuration Label Prints a configuration Status Receipt (Label).Same as
FEED button mode one flash routine.
^ID Object Delete Deletes objects from printer memory.
^TO Transfer Object Used to copy an object or group of objects from one
memory area to another.
^CM Change Memory Letter
Designation
Reassigns a letter designation to a printer memory
area.
^JB Initialize Flash memory Similar to formatting a disk. Erases all objects from the
specified memory locations B: or E:.
~JB Reset Optional Memory Similar to formatting a disk. Erases all objects from the
B: memory (factory option).

~DY Download Objects Downloads and installs a variety of printer-usable
programming objects: fonts (OpenType and TrueType),
graphics, and other object data types.
You can use ZebraNet Bridge to download graphics
and fonts to the printer.
~DG Download Graphic Downloads an ASCII Hex representation of a graphic
image. This is used by ZebraDesigner (label creation
application) for graphics.
^FL Font Linking Appends secondary TrueType font or fonts to the
primary TrueType font to add glyphs (characters).
^LF List Font Links Prints a list of the linked fonts.
^CW Font Identifier Assigns a single alphanumeric character as an alias to
a font stored in memory.
Table 17Object Management and Status Report Commands(Continued)
IMPORTANT: Some ZPL fonts that are factory-installed in yourprinter cannot be copied, cloned,
or restored to the printer by reloading or updating firmware. If these license-restricted ZPL fonts
are removed using an explicit ZPL object delete command, they must be repurchased and
reinstalled using a font activation and installation utility. EPL fonts do not have this restriction.

Glossary
Glossary
alphanumeric
Indicating letters, numerals, and characters such as punctuation marks.
backfeed
When the printer pulls the media and ribbon (if used) backward into the printer so that the beginning of
the label to be printed is properly positioned behind the printhead. Backfeed occurs when operating the
printer in Tear-Off and Applicator modes.
barcode
A code by which alphanumeric characters can be represented by a series of adjacent stripes of different
widths. Many different code schemes exist, such as the universal product code (UPC) or Code 39.
black mark media
Media with registration marks found on the underside of the print media that act as start-of-label indications
for the printer. The reflective media sensor is the generally-selected option for use with black mark media.
Contrast this with continuous media on page 385 or gap/notch media on page 387.
calibration (of a printer)
A process in which the printer determines some basic information needed to print accurately with a
particular media and ribbon combination. To do this, the printer feeds some media and ribbon (if used)
and senses whether to use the direct thermal or thermal transfer print method, along with (if using non-
continuous media) the length of individual labels or tags.
384
Glossary
collection method
Select a media collection method that is compatible with your printer options. Selections include tear-off,
peel-off, cutter, and rewind. The basic media and ribbon loading instructions are the same for all collection
methods with some additional steps necessary for using any media collection options.
configuration
The printer configuration is a group of operating parameters specific to the printer application. Some
parameters are user selectable, while others are dependent on the installed options and mode of
operation. Parameters may be switch selectable, control panel programmable, or downloaded as ZPL II
commands. A configuration label listing all the current printer parameters may be printed for reference.
continuous media
Label or tag-stock media that does not have gaps, holes, notches, or black marks to indicate label
separations. The media is one long piece of material wound into a roll. This allows the image to be printed
anywhere on the label. Sometimes a cutter is used to cut apart individual labels or receipts.
A transmissive (gap) sensor is typically used for the printer to detect when the media runs out.
Contrast this with black mark media on page 384 or gap/notch media on page 387.
core diameter
The inside diameter of the cardboard core at the center of a roll of media or ribbon.
diagnostics
Information about which printer functions are not working that is used for troubleshooting printer problems.
die-cut media
A type of label stock that has individual labels stuck to a media liner. The labels may be lined up against
each other or separated by a small distance. Typically the material surrounding the labels has been
removed. (See non-continuous media on page 389.)
385
Glossary
direct thermal
A printing method in which the printhead presses directly against the media. Heating the printhead
elements causes a discoloration of the heat-sensitive coating on the media. By selectively heating the
printhead elements as the media moves past, an image is printed onto the media. No ribbon is used with
this printing method.
Contrast this with
thermal transfer on page 392.
direct thermal media
Media that is coated with a substance that reacts to the application of direct heat from the printhead to
produce an image.
fanfold media
Non-continuous media that comes folded in a rectangular stack and folded in a zigzag pattern. Fanfold
media is either gap-notch media or black mark media, meaning it uses black marks or notches to track
media format positioning.
Fanfold media can have the same label separations as non-continuous roll media. The separations fall
either on or near the folds.
Contrast this with roll media on page 391.
firmware
This is the term used to specify the printer's operating program. This program is downloaded to the printer
from a host computer and stored in flash memory. Each time the printer power is turned on, this operating
program starts. This program controls when to feed the mediaforward or backward and when to print a
dot on the label stock.
FLASH memory
Non-volatile memory that maintains the stored information intact when power is off. This memory area is
used to store the printer's operating program. Can also be used to store optional printer fonts, graphic
formats, and complete label formats.
font
A complete set of
alphanumeric characters in one style of type. Examples include CG Times™, CG
Triumvirate Bold Condensed™.
386
Glossary
gap/notch media
Media that contains a separation, notch, or hole, indicating where one label/printed format ends and the
nextbegins.
Contrast this with black mark media on page 384 or continuous media on page 385.
ips (inches-per-second)
The speed at which the label or tag is printed. Many Zebra printers can print from 1 ips to 14 ips.
label
An adhesive-backed piece of paper, plastic, or other material on which information is printed. A non-
continuous label has a defined length, as opposed to a continuous label or a receipt which can have a
varying length.
label backing (liner)
The material on which labels are affixed during manufacture and which is discarded or recycled.
label type
The printer recognizes the following label types.
Continuous
Gap/Notch
387
Glossary
Mark
void
A space on which printing should have occurred, but did not due to an error condition such as wrinkled
ribbon or faulty print elements. A void can cause a printed barcode symbol to be read incorrectly or not at
all.
LCD (liquid crystal display)
A backlit display that provides the user with either operating status during normal operation or option
menus when configuring the printer to a specific application.
LED (light emitting diode)
Indicators of specific printer status conditions. Each LED is either off, on, or blinking depending on the
feature being monitored.
linerless media
Linerless media does not use backing to keep the layers of labels on a roll from sticking to one another.
It is wound like a roll of tape, with the sticky side of one layer in contact with the non-sticky surface of the
one below it. Individual labels may be separated by perforations, or they can be cut apart. Because there is
no liner, more labels can potentially fit on a roll, cutting down the need to change media as often. Linerless
media is considered an environmentally-friendly option because no backing is wasted, and the cost per
label can be considerably less than that of standard labels.
mark media
See black mark media on page 384.
388
Glossary
media
Material onto which data is printed by the printer. Types of media include: tag stock, die-cut labels,
continuous labels (with and without media liner), non-continuous media, fanfold media, and roll media.
media sensor
This sensor is located behind the printhead to detect the presence of media and, for
non-continuous
media, the position of the web, hole, or notch used to indicate the start of each label.
media supply hangar
The stationary arm that supports the media roll.
non-continuous media
Media that contains an indication of where one label/printed format ends and the next one begins. Types
of non-continuous media include gap-notch media and black mark media. (Contrast this with continuous
media.)
Non-continuous roll media usually comes in the form oflabels with an adhesive backing on a liner. Tags (or
tickets) are separated by perforations.
Individual labels or tags are tracked and position-controlled using one of these methods:
• Web media separates labels by gaps, holes, or notches.
• Black mark media uses pre-printed black marks on the back side of the media to indicate label
separations.
389
Glossary
• Perforated media has holes—to allow the labels or tags to be separated from each other easily—along
with position-control marks, notches, or label gaps.
non-volatile memory
Electronic memory that retains data even when the power to the printer is turned off.
notched media
A type of tag stock containing a cutout area that can be sensed as a start-of-label indicator by the printer.
This is typically a heavier, cardboard-like material that is either cut or torn away from the next tag. See
gap/
notch media on page 387.
peel-off mode
A mode of operation in which the printer peels a printed label away from the backing and allows the user
to remove it before another label is printed. Printing pauses until the label is removed.
perforated media
Media with perforations that allow the labels or tags to be separated from each other easily. The media
may also have black marks or other separations between labels or tags.
print speed
The speed at which printing occurs. For thermal transfer printers, this speed is expressed in terms of inches
per second (ips).
print type
The print type specifies whether the type of mediabeing used requires ribbonto print. Thermal
transfermedia requires ribbon while direct thermalmedia does not.
printhead wear
The degradation of the surface of the printhead and/or the print elements over time. Heat and abrasion
can cause printhead wear. Therefore, to maximize the life of the printhead, use the lowest print darkness
setting (sometimes called burn temperature or head temperature) and the lowest printhead pressure
390
Glossary
necessary to produce good print quality. In the thermal transferprinting method, use ribbonthat is as wide
or wider than the media to protect the printhead from the rough media surface.
Radio frequency identification (RFID) "smart" media
Each RFID label has an RFID transponder (sometimes called an "inlay"), made of a chip and an antenna,
embedded between the label and the liner. The shape of the transponder varies by manufacturer and is
visible through the label. All "smart" labels have memory that can be read, and many have memory that can
be encoded.
RFID media can be used in a printer that is equipped with an RFID reader/encoder. RFID labels are made
from the same materials and adhesives as non-RFID labels.
receipt
A receipt is a variable length printout. One example of a receipt is in retail stores, where each purchased
item occupies a separate line on the printout. Therefore, the more items purchased, the longer the receipt.
registration
Alignment of printing with respect to the top (vertical) or sides (horizontal) of a label or tag.
ribbon
Ribbon is a thin film that is coated on one side with wax, resin, or wax resin (usually called ink), which
is transferred to the media during the thermal transfer process. Ink is transferred onto the media when
heated by the small elements within the printhead.
Ribbon is only used with the thermal transfer print method. Direct thermal media does not use ribbon.
When ribbon is used, it must be as wide as or wider than the media being used. If the ribbon is narrower
than the media, areas of the printhead are unprotected and subject to premature wear. Zebra ribbons have
a coating on the back that protects the printhead from wear.
ribbon wrinkle
A wrinkling of the ribbon caused by improper alignment or improper printhead pressure. This wrinkle can
cause voids in the print and/or the used ribbon to rewind unevenly. This condition should be corrected by
performing adjustment procedures.
roll media
Media that comes supplied rolled onto a core (usually cardboard). It can be continuous (no separations
between labels)
391
Glossary
or non-continuous (some type of separation between labels).
Contrast this with fanfold media on page 386.
supplies
A general term for media and ribbon.
symbology
The term generally used when referring to a barcode.
tag stock
A type of media having no adhesive backing but featuring a hole or notch by which the tag can be hung
on something. Tags are usually made of cardboard or other durable material and are typically perforated
between tags. Tag stock can come on rolls or in a fanfold stack. (See
gap/notch media on page 387.)
tear-off mode
A mode of operation in which the user tears the label or tag stock away from the remaining media by hand.
thermal transfer
A printing method in which the printhead presses an ink or resin coated ribbon against the media. Heating
the printhead elements causes the ink or resin to transfer onto the media. By selectively heating the
printhead elements as the media and ribbon move past, an image is printed onto the media.
Contrast this with direct thermal on page 386.
