OPERATING PRECAUTIONS
Please follow the precautions shown below to ensure full functionality of the printer and thermal paper.
■Printer
Switch the power off when not in use.
DO NOT give a shock intentionary by dropping or hitting the printer. The printer with a rubber
cover has an excellent structure against impact on each surface. However, it may be broken
depending on the surface conditions, the angle of fall or the degradation state of the printer, and so
forth.
Give attention to ambient temperature and humidity during use of the printer. Proper operating
environment is as follows:
Ambient temperature: -15 C to 50 C / 5 F to 122 F
Relative humidity: 10% to 85%RH (no-condensing)
DO NOT set/put the printer near any device that generates strong electromagnetic fields, like a
motor in a copying machine.
DO NOT open the paper cover during printing.
DO NOT remove or reinstall the interface cable during printing or transmission. DO NOT touch the
connectors of the interface cable during printing.
NEVER close the paper outlet port or press down the paper which came out. If not, it might cause
paper jam.
Cut only a part of liner with the paper cutter attached to the paper outlet. It may cause a cutting
error or make the cutting edge dull due to label adhesive sticking to the cutter if cutting a part of
label sheet.
Remove the battery pack, when you do not use the printer for long periods of time. If not, it might cause
excessive discharge and then will not allow you to use the printer even after it is charged.
Clean the printer exterior with a soft, lint-free cloth where necessary. DO NOT use alcohol and
other solvent.
Before use, always clean the terminals using a dry, soft, lint-free cloth. If the terminals are dirty, it
may not allow you to ensure proper contact.
 Be sure to wipe the printhead with a soft swab, etc. when cleaning the thermal printhead.
 Unplug the AC cable except when using the AC adapter.

- 14 -
 When storing the battery pack for long periods of time, keep it in a cool place. If possible, avoid
long-term storage in the fully charged state. It may affect the battery life.
 Clean the terminals of the battery pack regularly (wipe them with a dry cloth).
 In order to fully demonstrate the performance of the battery pack, charge the battery at room
temperature and the temperature of the battery pack ranging from 0 C to 35 C / 32 F to 95 F.
 Clean the terminals of the dedicated charger regularly (wipe them with a dry cloth).
 DO NOT connect the AC cable of the AC adapter or the charger to the power supply wall socket
which was already connected to any other devices which generate noise.
High-print-rate printing might cause irregular printouts or generate loud noise. This is not a failure
in the printer, but an inherent paper phenomenon.
Always use roll paper whose width is at least 4 mm wider than the print width.
To ensure the bar code printing quality, parts having high printed ratios may be light at a low
temperature.
When using a Bluetooth interface, the radio environment around the printer may cause a failure in
communications. This is due to the specifications of Bluetooth, which is a radio communications
standard.
When handling this product, be aware of static electricity. If the static electricity is discharged, this
could case communication failure. When this problem occurs, disconnect the USB connector that
is connected to the host device and wait few seconds before connect it again.
If dew condensation occurs on the roll label, the peel function may not work well or paper jam may
occur. Avoid drastic changes in the environment.

- 15 -
■Thermal Paper
Store the paper in a cool, dry, and dark place.
DO NOT rub the paper with hard objects.
DO NOT leave the paper near organic solvents.
DO NOT allow the paper to touch plastic film, eraser, or adhesive tape for long periods of time.
DO NOT stack the paper together with diazo and wet-type copies immediately after copying.
DO NOT use chemical glue when starching up.
Always use the specified thermal paper. See Section 13, Optional Units and Consumables, for
details.

(1) POWER button
This button is used to turn the printer ON and
OFF. To power the printer on, hold down the
POWER button until the POWER lamp lights. To
turn the printer off, hold down the POWER button
until the POWER lamp goes off.
(2) FEED button
This button is used to feed the paper. Once this
button is pressed when using the marked paper,
the paper is fed to the start of the next paper.
Once this button is pressed when not using the
marked paper, the paper is slightly and gradually
fed. Continuing pressing this button advances
paper feeding.
(3) REPRINT button
This button is used to print the previous print
again. Reprint is available when the REPRINT
lamp lights. When the button print is valid, the
REPRINT button has the function to start the next
print. When the REPRINT lamp is blinking 3 times
(fast blinking), the REPRINT button cancels the
“suspension” and can start the next print.
(4) POWER lamp
The POWER lamp lights when the printer is
turned on. See the Power Lamp Indication shown
on page 21 for details.
