Precautions During Use
To ensure that your printer provides you with the many years of operation for which it is
designed, be sure to note the important precautions described below.
• Avoid using the printer in any location where any of the following is present: exposure
to direct sunlight, high humidity, static electric charge, extreme temperature
fluctuations, extreme temperatures. The operating temperature range of the printer is:
10°C to 35°C (50°F to 95°F).
• Do not subject the printer to strong impact.
• Do not allow paper clips or pins to get into the printer.
• Do not forcibly pull tape out of or push it back into the printer.
• Avoid allowing tape cuttings to accumulate around the printer tape outlet. Printing a
continuous series of multiple labels can cause printed tape to pile up at the tape outlet,
and/or tape cuttings to accumulate around the tape outlet or get inside the printer. Such
conditions can cause errors, interfere with proper tape cutting, or other malfunctions.
Use tweezers or a cotton swab to remove tape cuttings as required.
• Dirt or other foreign matter adhering to the printer head can cause horizontal stripes of
missing dots on printed tapes. If this happens, clean the print head and the rubber roller
as described under “User Maintenance” (page 32).
• Using the printer in a location exposed to strong direct sunlight can cause malfunction
of the printer’s internal light sensor, resulting in display of error messages.
• In order to ensure best printer function and stability, always use only genuine CASIO
tape cartridges. Use of a non-CASIO tape cartridge can harm your printer, result in poor
printing quality, and cause other problems that can permanently affect the printer’s
ability to perform at the level for which it was designed. Also note that problems caused
by use of a non-CASIO tape cartridge are not covered by the printer’s warranty, so any
charges required for servicing and repair must be borne by you.
Precautions when Using Wireless LAN
• Check to make sure that there are no other wireless network devices in use nearby
before using this printer’s wireless LAN function.
• Maintain a distance of at least two meters between the printer and other devices
(electrical appliances, audio/visual equipment, office equipment, digital cordless
telephones, fax machines, etc.) whenever performing wireless LAN data
communication. In the case of a microwave oven, maintain a distance of at least three
meters. Locating the printer too close to such a device while the device is turned on
can cause data communication problems, TV or radio static or interference, or other
problems. It can also cause distortion of UHF and broadcast satellite television images
on certain channels.
• If data communication is not possible when located close to a broadcasting station,
wireless device, or other similar equipment, move the printer to another location and try
again. Proper data communication may not be possible in a location where strong radio
waves are present.

You can select either of the following print modes: Normal Print, Magnetic Tape. Select
the print mode on the LABEL DESIGN MAKER setting screen.
• Normally, you should use the Normal Print mode.
Printing on Magnetic Tape
• Use the LABEL DESIGN MAKER label printing software. The LABEL DESIGN MAKER
phone app does not support magnetic tape printing.
• Configure the following settings: Tape Size: 24 mm (16 mm), Print Mode: Magnetic
Tape.
• Normally use a print density setting of 3 when printing with the Magnetic Tape mode. If
printing is not clear at this setting, adjust print density as required.
• Note that selecting Magnetic Tape automatically disables auto cutting. After printing on
magnetic tape, feed the tape and then use scissors to cut it.
• Magnetic tape is made using special materials. Because of this, you may not be able to
achieve clear printing under low temperatures. Printing on magnetic tape in a location
where the temperature is 20°C or higher is recommended. Also make sure that the tape
has been in the location long enough to become acclimated.
Printing Consecutive Labels
Normally, the printer will cut the tape automatically after printing is complete. When you
start a new printing operation, the printer will first feed the tape a fixed amount, which
means that some tape is wasted. To eliminate this wasted tape, you can disable the tape
cut operation at the end of each label and have consecutive labels printed on a continual
piece of tape (Continual Printing). After printing of all the labels is complete, you press
to cut off the tape, and then separate the labels by cutting with scissors.
To enable continual printing, select the check box next to the Continual Print option on
the LABEL DESIGN MAKER setting screen.

Printing Label Data From Printer Memory
Your printer’s Reprint function and Memory Print function let you print label data from
printer memory.
Re-printing the Last Label Printed (Reprint)
Reprint lets you re-print the last label you printed.
You can re-print even when the printer is not connected to a computer or phone.
This comes in handy when you need one more copy of a label you just printed.
1. Press .
• This prints one copy of the last label that was printed.
• During printing, the status lamp flashes green.
• The print setup used is the same as the one in effect for the last label you printed.
Important!
• Even if you printed multiple copies of the last label, Reprint will print only one copy.
• Note that turning off printer power or initializing printer settings (page 26) will clear the
Reprint memory data, so re-printing of that data will not be possible.
• You can interrupt an on-going printing operation by pressing
. After printing stops,
cut the tape manually. (page 27)
Printing Data Stored in Printer Memory (Memory Print)
With Memory Print, you can store label data in printer memory and print it when needed.
You can perform Memory Printing even when the printer is not connected to a computer
or phone.
This feature comes in handy when you need to print certain data multiple times during the
day.
To store Memory Print data
1. Print the label whose data you want to store.

2. After printing is complete, hold down for at least three seconds. Release the key
when the status lamp lights green.
• The status lamp will remain lit for about one second, indicating that the Memory
Print data was saved.
• Memory Print data is not cleared if you turn off printer power or print a different
label. For information about how to delete Memory Print data, see “To delete
Memory Print Data” below.
Important!
• Data for only one label can be stored in printer memory. Storing data for a different
label will overwrite any Memory Print data currently in memory.
• You can interrupt an on-going printing operation by pressing
. After printing stops,
cut the tape manually. (page 27)
• Memory Print data will be viewable by third parties if your printer is ever stolen, if
you dispose of the printer, or if the printer is transferred to a third party by any other
means. Because of this, you should not leave personal information stored in printer
memory.
To print Memory Print data
1. Press .
• During printing, the status lamp flashes green.
• The print setup is the same as the one in effect for the print data you save. For
example, if you save data with Full Cut Only, printing the saved data will be
performed with Full Cut Only.
To delete Memory Print data
1. Turn printer power off and then back on again.
2. Hold down for at least three seconds.
• The status lamp will remain lit for about one second, indicating that the Memory
Print data was deleted.
• You can also clear Memory Print data by initializing the printer (page 26).
