

Be careful about the ambient temperature and humidity.
Suitable environment for the use of the printer is as follows:• Range of the temperature : 5°C to 45°C (41°F to 113°F)• Range of the humidity: 10%RH to 90%RH (Non condensing)See "16. SPECIFICATIONS" for the guaranteed humidity range at each temperature.


DO NOT install the products near devices that generate strong magnetism such as a copy
machine motor.



DO NOT install the products in a location that is subject to corrosive gas, siloxane and so on.

DO NOT connect the AC adapter or AC cable to the same outlet with devices that generate noise.

Precautions on use and operation

DO NOT print without the thermal paper.

DO NOT use thermal papers taped together.



NEVER forcibly pull out the thermal paper by hand with the thermal paper loaded.



DO NOT open the top cover during printing or cutting.



DO NOT connect or disconnect the interface cable during printing or communication.
DO NOT touch the plug of the interface cable during printing.

When handling the printer, be aware of static electricity. When the static electricity is discharged,
this could cause a USB communication failure.
When this problem occurs, disconnect the USB plug that is connected to the host device and waita few seconds before connecting it again.

DO NOT use the thermal head when it is wet. Doing so may damage the printer.



Printing under low temperature environment or printing at a high print rate might cause unclear
printing or generate loud sound. This is not a failure in the printer but an inherent paper
phenomenon.

When printing at a high print rate for longer length, even non-printing area may be colored due toaccumulation of heat in the thermal head.
Verify the performance with your actual device in advance.



Do not stop the printer as it is after printing barcode or image whose print rate is high.
Paper feed difficulty may be caused because the thermal paper surface and the thermal head may
stick together. To prevent from the occurrence of the paper feed difficulty, feed the thermal paper
after printing.

5The print quality of linerless label may be affected by the storage environment and storage period,
so verify the performance with your actual device in advance.

Paper feeding may be confused a few dot-lines when printing is started or when printing andpaper feeding are resumed from a pause state. When printing bit images and so on, always feed
the thermal paper for at least 24 steps at the start of printing, and print without interrupting.



The AC adapter may get a little hot when in use. This is normal and not a malfunction.



Always use the specified thermal paper. See "17. ACCESSORIES AND CONSUMABLE PARTS"
for details.



DO NOT touch the thermal head directly. Doing so may result in poor printing quality due to thedirt or damage by the static electricity.



NEVER touch the thermal head, paper sensor, or platen roller directly while opening the top cover
to install the thermal paper. Doing so may cause injury or other accidents.

Be careful not to get your fingers or hands caught in the printer when opening or closing the top
cover.

The autocutter printer has an exposed cutter blade in the paper outlet. Do not insert fingers into
printer.
NEVER touch the cutter blade while the top cover of the printer is open.

In order to ensure the function and the safety of the product, be sure to observe the installation
direction.





NEVER connect the USB cable or Ethernet cable to the RJ connector.



DO NOT drop or insert any foreign objects such as clips, pins, and screws in the internal parts or
slot of the products.



DO NOT drop any liquid or spray a solvent to the products.



NEVER use sharp object such as pen tip to push the switch on the operation panel.



Make sure not to injure your body or other objects by the plate edge.

As the plated sheet steel is used in the printer, the edge face might rust.

When moving the printer from the installation site, hold the printer tightly with both hands, then lift
it upward slowly to leave the rubber feet from the installation surface. Lifting it rapidly or moving it
horizontally may peel the entire rubber feet, peel their surfaces, or damage the outer case.

When something goes wrong with the printer during use, stop using it immediately, and unplug theAC plug from the outlet.



NEVER disassemble the printer without a serviceman.

Precautions for Wireless communication
When using the Bluetooth interface, the communication may become unstable due to the
influence from external radio waves. This is based on Bluetooth specification which is a wirelesscommunication standard.



The Bluetooth model operates in the 2.4 GHz frequency range. The Wireless LAN model using
IEEE802.11b/g/n operates in the 2.4 GHz frequency range, and IEEE802.11a/n operates in the 5
GHz frequency range. So if these models are used around other wireless LAN or any equipmentusing the same frequency range such as a microwave oven, radio frequency interference may
occur, and the communication may become unstable. When it happens, turn off the interfering
equipment or increase the distance. Alternatively, shorten the distance between the host device
and the printer as much as possible.
6

When operating the Wireless LAN model using IEEE 802.11a/n, the printer may stop
communication temporarily before outputting radio wave to the target channel not to affect theweather radar, air traffic control radar or others. This is to monitor the presence of radar waves fora certain time. If the printer detects radio waves such as radar during operation, it may switch toanother channel.

Precautions for maintenanceClean the products' cases using a soft and lint-free cloth. DO NOT use alcohol or other solvent.

Before using, clean the terminals using a dry, soft, and lint-free cloth when they are dirty. If theterminals are dirty, it may cause contact failure.

When cleaning the thermal head, always wipe it with a cotton swab or other soft material.

When cleaning the cutter, use a thin wooden or plastic stick to avoid scratching the blade.

Precautions for storing

Turn off the printer when not in use.
In addition, when the printer is not used for a long time, unplug the AC cable from the outlet.
Moreover, set thermal paper to protect the platen.

■Thermal Paper HandlingStore the thermal paper in a cool, dry, and dark place.



DO NOT rub the thermal paper with hard objects.



DO NOT leave the thermal paper near organic solvents.



DO NOT allow PVC film, erasers, or adhesive tape to touch the thermal paper for long periods.



DO NOT stack the thermal paper with diazo copies immediately after copying.



DO NOT use chemical glue.



DO NOT use 2-ply thermal paper and perforated thermal paper.

■Precautions on Discarding
When discarding used products, discard them according to the disposal regulations and rules of each
district.
