Definitions of warnings, cautions, and notes
We use the following terms throughout this User’s Guide:
You must follow these warnings to prevent possible personal injury.
You must follow these instructions to make sure you use the printer properly and do not damage it.
Remember these useful tips when you use the printer.

ii
To use the printer safely
The fusing unit becomes extremely hot during operation. Wait until it has cooled down sufficiently
before replacing consumable items.
The fusing unit is marked with the caution label. Please do NOT take off or damage the label.
There are high voltage electrodes inside the printer. Before you clean the printer, clear a paper jam
or replace parts, make sure you have turned off the power switch and unplugged the printer from
the AC power outlet/socket.
Do not handle the plug with wet hands - this constitutes an electric shock hazard.
This printer is heavy and weighs approximately 31.5 kg (69.4 lb). When you move or lift this printer,
make sure at least two people lift it together. Be careful not to trap your fingers when you set the
machine back down.

iii
If the printer becomes hot, blows smoke, or generates obscure odor, immediately turn off the power
switch and unplug the printer from the AC power outlet/socket. Call your dealer or Brother
Customer Service.
If metal objects, water or other liquids get inside the printer, immediately turn off the power switch
and unplug the printer from the AC power outlet/socket. Call your dealer or Brother Customer
Service.
Do not put consumable items such as the toner cartridges and the waste toner pack into a fire.
Some consumable items can be flammable under certain conditions.
Do not look directly at the laser beam light. It might cause damage to your eyesight. Do not remove
or break open the printer's safety interlocks.
Do not run the printer with the top cover, front cover and back covers open and the interlocks
removed.
Do not place any items on the printer.

iv
Printer do’s and don’ts for optimum print quality
Before you move or lift the printer, remove the toner cartridges, waste toner pack and fusing unit
to avoid spills. Be sure to keep the printer as level as possible. Damage caused by failure to remove
the supplies may void your warranty.
Do not touch the rollers of the fusing unit. This can degrade print quality.

v
IMPORTANT: For technical and operational help, you must call the country where you bought the
printer. Calls must be made from within that country.

1 - 5 ABOUT THIS PRINTER
Features
This printer has the following standard features.
2400 DPI class resolution
This printer prints at a default resolution of 600 dots per inch (dpi). You can get a higher print quality,
equivalent to 2400 dpi class resolution by using Brother technologies: High Resolution Control (HRC)
and Color Advanced Photoscale Technology (CAPT).
High speed and color laser printing
You can print crisp images in brilliant 24-bit color.
This printer can print at speeds up to 29 pages per minute in monochrome mode and 8 pages per minute
in full color mode. The HL-2700CN controller uses a high speed 64-bit RISC microprocessor and special
hardware chips, to ensure fast print job processing.
Color Advanced Photoscale Technology (CAPT)
This printer can print graphics in 256 shades for each color in PCL6 emulation and BR-Script3, producing
nearly photographic quality. CAPT is most effective when printing photographic images.
High Resolution Control (HRC)
The High Resolution Control (HRC) technology gives you clear and crisp printouts and improves even
600-dpi resolution output. HRC is most effective when printing text.
Maintenance-free and economical toner cartridge
This printer uses four easy-to-replace toner cartridges. The toner cartridges can print up to 6,600 (Cyan,
Magenta and Yellow) and 10,000 (Black) single-sided pages at approximately 5% coverage.
Universal paper tray
This printer loads paper automatically from the paper tray. Since the paper tray is a universal type, a
number of different paper sizes (one paper size at a time) can be used. Even envelopes can be loaded
from the paper tray. For detailed paper specifications, see What kind of paper can I use? on page 1-10.
Three interfaces
This printer has a high speed, bi-directional parallel, a Hi-Speed USB 2.0, and an Ethernet
10/100BASE-TX interface.
If your application software supports the bi-directional parallel interface, you can monitor the printer
status. It is fully compatible with the industry-standard bi-directional parallel interface.
The Brother network board is factory installed in the HL-2700CN, which enables you to use this printer
in the TCP/IP, IPS/SPX, AppleTalk, DLC/LLC and NetBEUI environments. Also, many useful utilities,
such as BRAdmin Professional utility for the administrator and Brother network printing software, are
included in the CD-ROM supplied with the HL-2700CN printer. For setup, see the Network User's Guide,
which is provided on the CD-ROM.

ABOUT THIS PRINTER 1 - 6
Automatic Interface Selection
This printer can automatically select the bi-directional parallel, USB or Ethernet 10/100BASE-TX
interface, depending on the interface port through which it receives data. With this feature, you can
connect the printer to more than one computer. See Automatic Interface Selection on page 2-20.
Five emulation modes
This printer can emulate PCL 5C and PCL 6 language printers, Brother BR-Script3 printers, HP-GL
plotter as well as EPSON FX-850 and IBM Proprinter XL printers (for monochrome printing only). You
can print with all application programs that support one of these printers. See About emulation modes
on page 3-21.
Automatic Emulation Selection
This printer can automatically select the printer emulation mode, depending on the print commands it
receives from the computer software. With this feature, many users can share the printer on a network.
See Automatic Emulation Selection on page 2-19.
Data compression technology
This printer can internally compress the received graphics and font data in its memory so it can print
larger graphics and more fonts without the need for additional memory.
Fonts

Panel lock setting
If the panel button settings have been changed, the printer may not work as you expect. If you are an
administrator of this printer, you can lock your settings to prevent changes from being made. See SETUP
on page 3-12.
Power Save Mode
This printer has a power saving mode. Since laser printers consume power to keep the fixing assembly
at a high temperature, this feature can save electricity when the printer is on but not being used. The
factory setting of the power save mode is ON so that it complies with the new EPA Energy Star
specification.
Toner Save Mode
This printer has an economical toner save mode. By using this feature you can substantially reduce
operating costs and extend the life expectancy of the toner cartridges.
Reprint setting
The printer saves data that you want reprinted. You can reprint a document without sending the data
again from your PC. If you do not install a CompactFlash
®
card, you can reprint from RAM. See Reprint
setting on page 3-26.
When there is not enough memory to print the last job, you can reprint the last print page.

ABOUT THIS PRINTER 1 - 14
Guidelines for selecting paper
The printer is designed to work well with most types of xerographic and bond paper. However, some
paper variables may have an effect on print quality or handling reliability. Always test samples of paper
before purchasing to ensure desirable performance. Some important guidelines when selecting paper
are:
■ Supplier should be informed that the paper or envelopes will be used in a laser printer.
■ Preprinted paper must use inks that can withstand the temperature of the printer's fusing process.
(200 degrees centigrade)
■ If you have selected a cotton bond paper, paper having a rough surface, such as cockle or laid
finished paper or paper that is wrinkled or puckered, the paper may exhibit degraded performance.
Types of paper to avoid
Some types of paper may not perform well or may cause damage to your printer.
Do not use paper:
■ that is highly textured
■ that is extremely smooth or shiny
■ that is curled or warped
■ that is coated or has a chemical finish
■ that is damaged, creased or folded
■ that exceeds the recommended weight specification in this guide
■ with tabs and staples
■ with letterheads using low temperature dyes or thermography
■ that is multipart or carbonless
■ that is designed for inkjet printing
If you use any of the types of paper listed above, they may damage your printer. This damage is not
covered under any Brother warranty or service agreement.
The manufacturer does not recommend the use of any particular paper. The operator is responsible
for the quality of paper used with the printer.

1 - 17 ABOUT THIS PRINTER
Labels and transparencies
The printer will print on most types of labels and transparencies designed for use with a laser printer.
Labels should have an adhesive which is acrylic-based since such material is more stable at the high
temperatures in the fusing unit. Adhesives should not come in contact with any part of the printer,
because the label stock may stick to the drum or rollers and cause jams and print quality problems. No
adhesive should be exposed between the labels. Labels should be arranged so that they cover the entire
length and width of the sheet. Using labels with spaces may result in labels peeling off and causing
serious jams or print problems.
All labels and transparencies used in this printer must be able to withstand a temperature of 200 degrees
centigrade (392 degrees Fahrenheit) for a period of 0.1 seconds.
Label and transparency sheets should not exceed the paper weight specifications described in this
User's Guide. Labels and transparencies exceeding this specification may not feed or print properly and
may cause damage to your printer.
Transparencies and Labels can be fed from Tray 1 only and cannot be printed using the duplex unit.
Types of labels and transparencies to avoid
Do not use labels or transparencies that are damaged, curled, wrinkled or an unusual shape.
Figure 1-11
Before using paper that has holes in it, such as organizer sheets, you must ‘fan’ the stack to avoid
paper jams and misfeeds.
Figure 1-12
■ Avoid feeding labels with the carrier sheet exposed because your printer will be damaged.
■ When feeding transparencies, use the recommended type for laser printers. For detailed
information on the specification of the proper transparencies to purchase, call your dealer or
Brother Customer Service.
Brother will not recommend particular labels or transparencies because the manufacturers may
change the specifications. You are responsible for the quality and performance of the print media
you use.

ABOUT THIS PRINTER 1 - 18
Paper feed
Tray feed
The printer can feed paper from the standard paper tray, optional lower tray or optional legal tray.
The printer automatically detects the paper size you have put into the paper tray. The printer will prompt
you to put the correct size of paper in the tray as follows:
If you want to put a different size of paper into the paper tray from the size that was selected in the paper
size setting by using the control panel buttons or in your application software, you can change the paper
size setting.
Print on envelopes
Adjust the paper length and width guides to fit the envelopes that are going to be used.
Figure 1-13
When you put paper into the paper tray, note the following:
■ If your application software supports paper size selection on the print menu, you can select it
through the software. If your application software does not support it, you can set the paper size
in the printer driver or by using the control panel buttons.
■ The paper size has been set at the factory to Letter for 120 V models or A4 for 220/240 V
models. If you want to use other sizes of paper or envelopes, change the paper size setting in
PAGE FORMAT in the FORMAT menu by using the control panel buttons. For paper size
selection, see PRINT MENU on page 3-13.
■ If you use pre-printed paper in the trays, please be sure to put the paper with the printed side
face up and the top edge of the paper at the back of the paper tray.
SIZE MISMATCH
Put <size> paper size in Tray
<1/2>. Paper mismatch between
the Printer and the Printer

1 - 19 ABOUT THIS PRINTER
Manual feed
Since this printer does not have a manual feed or multi purpose tray, you cannot manually feed irregular
sized paper. However, this printer has a special manual feed mode using Tray 1 (standard paper tray)
to accommodate non-standard paper sizes. You can select this mode with the printer driver or the control
panel buttons.
See PAPER in Chapter 3 for more information on selecting this setting using the printer control panel
buttons.
1
When the manual feed command is selected, the printer waits until you put the paper in Tray 1.
2
Pull out Tray 1 and put in the paper you are going to use. It may be necessary to remove some or
all of the paper stack first, depending on the size of paper in the tray and the size of the paper you
wish to print on manually.
3
Put Tray 1 back in and press Go. The printer will then start printing.
Paper output
We recommend that you use the face down output tray extension, paper stopper and paper support:

Automatic Interface Selection
This printer has an Automatic Interface Selection feature. When the printer receives data from the
computer, it automatically selects the IEEE 1284 Parallel or the USB interface, whichever is appropriate.
When you use the parallel interface, you can turn the high-speed and bi-directional parallel
communications on or off by using the control panel buttons to access PARALLEL in the INTERFACE
menu. See INTERFACE on page 3-17. Since the Automatic Interface Selection mode has been factory
set to ON, simply connect the interface cable to the printer. (Note: Always turn off both your computer
and printer when connecting or disconnecting the cable).
If you typically use only one interface, we recommend that you select that interface in the INTERFACE
mode. If only one interface is selected, the printer will allocate the entire input buffer to that interface.

Reprint setting
If you want to reprint a document that has just been printed, you can reprint it by using the control panel
button. Also, if you have created a document that you wish to share with colleagues, simply spool the
document to a non-secure area of the printer. This document can then be reprinted by anyone who is on
the network or at the printer control panel.
If you want to print PROOF, PUBLIC or SECURE data, we recommend that you install the optional
CompactFlash
®
card.
Reprinting from RAM
If you do not install a CompactFlash
®
card (see CompactFlash
®
card on page 4-11), you can reprint from
random access memory (RAM). The reprint data in RAM will be deleted when the printer is turned off.
When you use RAM to reprint:
1
Press the Set button on the control panel to exit from the READY state and select RAMDISK SIZE
in the SETUP menu.
2
The pre-set RAM disk is 0MB. Press the + button to increase the reprint RAM size in increments of
1MB.
We recommend that you add more RAM if you want to be able to print a lot of secured data. (See
SO-DIMM on page 4-13)
■ When you increase the RAM size for Secure Printing, the work area of the printer is decreased
and the printer performance will be reduced. Make sure that you reset the RAMDISK SIZE to
0MB after you finish using Secure Printing.
■ You can also save macros, the print log, and fonts on RAMDISK.
■ When you store data in RAM, the data will be deleted when the printer is turned off.

Toner cartridges
A new toner cartridge contains enough toner to print up to 10,000 pages for Black and up to 6,600 pages
for Cyan, Magenta and Yellow A4 or Letter-size single-sided pages at about 5% coverage.
Toner nearly empty message
Check printed pages, page counter, and display messages regularly. If the indicator starts blinking,
the printer has nearly run out of toner or the toner is not evenly distributed inside the cartridge.
*K stands for Black, C stands for Cyan, M stands for Magenta and Y stands for Yellow.
Although you can print up to 300 (Black) and 500 (Cyan, Magenta and Yellow) additional pages (at 5%
coverage) after the TONER LOW message first appears, be sure to replace the toner cartridge with a new
one before it becomes completely empty. When this occurs, the indicator on the LCD panel will
disappear.
TONER EMPTY message
When the following message appears on the LCD panel and the printer stops printing, you need to
replace the toner cartridge:
■ The amount of toner used varies depending on how much print is on the page and the print
density setting.
■ If you change the print density setting for lighter or darker printing, the amount of toner that is
used will change.
■ Wait to unpack the toner cartridge until immediately before you install it in the printer.

Open the front cover of the printer.
Figure 5-1
2
Pull out the used toner cartridge.
3
Take the new toner cartridge out of the box.
Do not put the toner cartridge into a fire. It could explode.
■ Brother strongly recommends that you do not refill the toner cartridge provided with your printer.
We also strongly recommend that you continue to use only Genuine Brother Brand
replacement toner cartridges. Using or attempting to use potentially incompatible toner and /or
toner cartridges in your printer may cause damage to the printer itself and/or it may result in
unsatisfactory print quality. Our warranty coverage does not apply to any problem that was
caused by the use of unauthorized third party toner and toner cartridges. To protect your
investment and guarantee your print quality please continue to replace consumed toner
cartridges with only Genuine Brother Branded Supplies.
■ Printing with a third-party toner or third-party toner cartridges may reduce not only the print
quality but also the quality and life of the printer itself. It may also cause serious damage to the
performance and life of a drum unit. Warranty coverage does not apply to problems caused by
the use of third-party toner or third-party toner cartridges.
We recommend that you clean the printer when you replace the toner cartridge. See Cleaning on
page 5-21.
Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wipe
or wash it off with cold water.
■ Be sure to seal up the toner cartridge tightly so that toner powder does not spill out of the
cartridge.
■ Discard the used toner cartridge according to local regulations, keeping it separate from
domestic waste. If you have questions, call your local waste disposal office.

TROUBLESHOOTING 6 - 21
Setting up the printer
Question Recommendation
I cannot print from my
application software.
■ Make sure that the supplied Windows
®
printer driver is installed properly and
selected in your application software.
I cannot print the entire page. ■ Check that the size of paper in the feeder is the same as the paper size you
selected in your application or in the printer driver.
■ Check that the interface cable is connected to the printer and computer
securely.
Computer indicates a device
time-out.
■ If the Alarm LED is blinking, clear it and then try to print again. See LCD
messages on page 6-1 under Error messages.
■ If the Alarm LED is off, wait a short while and then click the Retry button in the
PC screen dialog box.
■ Check that the printer is on line.
Computer indicates paper is
empty.
Paper is empty. Put paper in the feeder, and then press
Go to recover from the
error status.
Computer indicates off line Press
Go to put the printer in the Ready state.
Computer indicates power is
off
Check that the printer is securely plugged into the AC power outlet/socket and
that the power switch is on.
Computer indicates an error
message other than above.
Check the following;
■ The computer can work in bi-directional mode.
■ The printer port is correct.
■ Selection of the printer is correct.

6 - 22 TROUBLESHOOTING
Paper handling
Question Recommendation
The printer does not feed
paper.
■ Check to see if the Alarm LED is on. If so, the paper tray may be out of paper
or not properly inserted. If it is empty, put a new stack of paper in the paper
tray.
■ If there is paper in the paper tray, make sure that it is straight. If the paper is
curled, you should straighten it before printing. Sometimes it is helpful to
remove the paper, turn the stack over, and then put it back in the paper tray.
■ Reduce the stack of paper in the paper tray, and then try again.
How can I load envelopes? You can feed envelopes from the paper tray (Tray 1). Make sure you adjust the
paper guide. Your application software also must be set up properly to print on
the size of envelopes you are using. This is usually done in the Page Setup or
Document Setup menu of your software. See your applications manual for more
information.
Which paper can I use? See What kind of paper can I use? on page 1-10 for detailed paper
specifications.
How can I clear paper jams? See Paper jams and how to clear them on page 6-7.
The printer feeds more than
one sheet at a time.
Check the following:
■ The paper in the tray is all the same type.
■ The paper meets the specifications.
■ Paper stack was fanned before loading.
■ The stack of paper is not too high.
■ The side guide is not set too tight.
Paper skews while feeding. Check the following:
■ The side guide is adjusted properly.
■ The amount of paper you loaded is correct. See Paper specifications on page
A-4.
Sometimes mis-picking of
paper from the paper tray or
mis-feeding of paper from the
paper exit occurs.
Clean the paper guide, the registration roller and the exit roller. See Cleaning on
page 5-21.

TROUBLESHOOTING 6 - 23
Printing
Question Recommendation
The printer prints
unexpectedly or it prints
incorrect characters.
■ Cancel the print job from your computer. Then, turn the printer off and on, or
reset the printer and try your print job again.
■ Make sure your application software is properly set up to use this printer.
Check the printer driver settings or printer settings in your application
software.
The computer hangs up when
the printer starts printing, or an
application error occurs.
Check to see that the system resources are enough (PC memory, etc.). When
you have many applications open, the system resources of your PC will not be
enough and will cause your PC to hang up. Close applications you are not using
and try again.
The headers or footers appear
when I view my document on
the screen but do not show up
when I print them.
Most laser printers have a restricted area that cannot be printed. Adjust the top
and bottom margins in your document to allow for this.
Printing takes too long. ■ Color graphic images contain a large amount of data and the printer will take
a relatively long time to complete printing.
■ When you print in Super Fine mode, the printer will take a relatively long time
to finish printing.
■ When the Status LED is blinking, the printer is getting ready to print. Print
speed depends on memory size or performance of your PC and memory size
of the printer.
The printer doesn't print in
color.
■ The printer may be set to monochrome mode.
