OPERATING PRECAUTIONS  
Please follow the precautions below to enjoy and maintain the full performance of the  
printer.  
Using the Printer  
u Be careful not to drop or bump the printer on a hard surface.  
u DO NOT install the printer in direct sunlight or such areas. Suitable environment for  
the use of the printer is as follows:  
· Ambient temperature: 32°F to 122°F (0°C to 50°C)  
· Relative humidity: 30 to 80%RH (noncondensing)  
u DO NOT install the printer near devices that generate strong electromagnetic fields  
such as a copy machine.  
u DO NOT install the printer in a location that is subject corrosive gas or siloxane and  
so on.  
u DO NOT connect the AC cables of the AC adapter and the battery charger to the  
same outlet with devices that generate noise.  
u DO NOT open the paper cover during printing.  
u DO NOT remove or reinstall the interface cable during printing or transmission. DO  
NOT touch the connectors of the interface cable during printing.  
u DO NOT cut any cut sheet or label paper with the paper cutter installed in the paper  
outlet. Failure to follow this instruction may cause a cutting error or make the cutting  
edge dull due to label paper adhesive sticking to the cutter.  
u Switch the power off when not in use.  
u Clean the printer using soft, lint-free cloth. DO NOT use alcohol or other solvent.  
u Before use, always clean the terminals using a dry, soft, lint-free cloth. If the  
terminals are dirty, it may not be possible to obtain proper contact.  
u When cleaning the TH, wipe the thermal head with a cotton swab or other soft  
material.  
u Remove the battery pack from the printer if the printer is not used for a long time. If  
not, it may cause overdischarge and shorten life span of the battery pack.  
u Store the battery pack in cool place. DO NOT store the battery pack for long time  
with fully charged condition because it may shorten life span of the battery pack.  
u The battery pack should be recharged at 32 to 95°F (0 to 35°C) for optimum  
performance.  
- 9 -  
Download from Www.Somanuals.com. All Manuals Search And Download.  
u The AC adapter, the battery charger and the battery pack may become warm when  
in use. This is normal and is not a malfunction.  
u When the battery pack is used at low temperature, the length of time the printer can  
be used may be shortened.  
u High-print-rate printing or using the printer under low temperature condition might  
cause irregular printouts or generate loud noise. This is not a failure in the printer,  
but an inherent paper phenomenon.  
u 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.  
u 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.  
Thermal Paper Handling  
u Store the thermal paper in a cool, dry, and dark place.  
u DO NOT rub the paper with hard objects.  
u DO NOT leave the paper near organic solvents.  
u DO NOT allow plastic film, erasers, or adhesive tape to touch the paper for long  
periods.  
u DO NOT stack the thermal paper with diazo copies immediately after copying or wet-  
type copies.  
u DO NOT use chemical glue.  
u Always use the specified thermal paper. See Section 12, Options and Consumable  
Parts, for details.

Place a cut sheet with the paper  
position detection mark facing up.  
(2) If the printer has been stored without  
thermal paper, open and close the  
paper cover (see Section 2 EACH  
PART OF PRINTER) before setting the  
cut sheet.  
(3) Insert a cut sheet into the paper slot in  
the printer until it stops with its printable  
surface facing down.  
(4) The printer detects the paper and loads  
it automatically.  
(5) To discharge the paper from the printer, hold down the FEED switch.  
CAUTION

7 CONNECTING TO THE HOST DEVICE  
This printer supports serial and USB communication through an interface cable and  
infrared communication based on IrDA (Ver1.2). Moreover, the Bluetoorh supported  
model supports Bluetooth (Ver.2.0+EDR)-compliant wireless communication.  
The printer function setting differs depending upon a communication method to be used.  
See Section 6 FUNCTION SETTINGS for details.  
An interface cable is required to perform serial or USB communication. See Section 11  
SPECIFICATIONS for details of interface specifications.  
The communication speed might be reduced depending on data processing by  
software as well as print type and size.  
NOTE: Unsupported Bluetooth printer does not support wireless communication.  
HINT  
Connecting the printer and the host device using the USB interface cable  
makes fix to communication method as USB communication mode  
regardless of selection of communication mode by the function setting.  
DO NOT connect the USB interface cable If other communication modes  
are required.

8 RECHARGING THE BATTERY PACK  
The battery pack is partially charged prior to shipping, and provides sufficient power to  
check the printer operation. To use the printer for an extended time, fully recharge the  
battery pack.  
This battery pack does not need to be used up or discharged before recharging.  
The battery pack can be recharged when it is installed in the printer connected with an  
AC adapter. The battery pack can also be recharged with exclusive battery charger.  
Recharging the Battery Pack in the Printer  
An AC adapter and an AC cable are required to recharge the battery pack in the printer.  
(1)Turn the printer off.  
(2)Install the battery pack in the printer.  
(3)Connect the AC adapter to the printer.  
(4)Plug the AC plug of the AC cable to the outlet.  
(5)Turn the printer on. After initialization, the POWER lamp starts blinking after lighting,  
recharging begins.  
(6)The POWER lamp will continue to blink while recharging. When recharging is  
complete, the POWER lamp lights continuously. At this time, when the paper is not  
set or the paper cover is opened, the ERROR lamp lights. The recharging time  
depends on the ambient temperature and the voltage level of the battery pack.  
Normally, it takes about 3 hours to recharge after running down a battery pack.  
NOTE  
-
DO NOT remove the battery during recharging. If it is removed during  
recharging, remove the AC plug from the outlet immediately. Never  
touch the battery terminal. Remove the interface cable from the  
connector during recharging.

HINT  
The printer can print or receive data while it is recharging the battery  
pack, too. While printing or receiving data, the POWER lamp lights  
continuously and the printer pauses to recharge. The printer recharges  
the battery again after printing and receiving data are completed.  
To stop recharging, press the POWER switch. The printer will turn off.  
To recharge the battery pack again, repeat the steps shown in (5).  
The battery pack should be recharged at 32 to 95°F (0 to 35°C) for  
optimum performance.  
If the Auto Activation by AC function is enabled, the printer turns on  
automatically when the AC cable of the AC adapter inserts to the outlet.  
See Section 6 Function Setting for details on settings.  
Recharging with Specified Battery Charger  
(1)Connect the AC cable to the battery charger.  
(2)Plug the AC plug of the AC cable to the outlet.  
(3)Install a battery pack in the battery charger. Make sure that electrodes of the  
battery pack contact the terminals of the metal on the battery charger.  
(4)The battery charger CHARGE lamp (red) will light and the battery charger will start  
recharging.  
(5)When the CHARGE lamp turns its lamp to green color, the battery pack is  
sufficiently recharged.  
(6) When recharging is complete, remove the battery pack.  
(7) Unplug the AC plug of the AC cable to the outlet.
