4.3 Verifying Battery Charge State

We strongly recommend testing your printer before returning it to Extech. Follow these steps to
identify and correct any battery power problem that may be encountered. These will help to
identify that the fault is with the printer and not some other part of your system.

To test the AC adaptor:

 Use a multi meter and measure the output voltage. Output should be 10VDC.
 Press the <ON/OFF> switch and wait until all LED’s are off.
 Insert the AC adaptor plug into the printer. If the amber LED goes on, the battery is not

fully charged but the charge circuit is functioning.

 The AC power portion of the circuit appears ok.

To test the DC power:

 Disconnect the AC Adapter once the battery has charged for 5 minutes or so.
 Press and hold the <FEED> switch, then press and release the <ON/OFF> switch and then

release the <FEED> switch. The printer will print a “self test” receipt

 If the self test receipt is printed, the DC power is ok.

To test if the battery is accepting charge:

 Press <ON/OFF> switch and wait until all LED’s are off
 Plug the AC power adapter into the printer. Press <ON>; the green LED is illuminated and

after about 20 seconds the LED should go off

 If the amber LED is on, this will continue on through this test indicating that the battery is

accepting a charge and that the charge circuit is ok. At the end of a 180 minute charge
cycle the LED will go off.

4.4 Battery and Safety Information

The printer is powered by a 7.4V Li-Ion battery cartridge.

 Charging time in the printer is approximately 3.0 hours.
 Take the battery out of printer if storing the printer for long periods of time.
 The battery storage temperature is 40°F to 104°F (4°C to 40°C). Do not store a fully charged

battery at temperatures greater than 104°F (40°C) for long periods of time – the battery may
permanently lose charge capacity.

 The recommended temperature for charging is between 68°F (20°C) to 77°F (25°C).
 Be sure to use a fully charged battery before long or battery intensive printing sessions.

Certain operations (for example, printing receipts with a lot of bar codes and graphics) drain
the battery more quickly than others.

 Dispose according to your local regulations. Do not throw in trash.

Do not disassemble, short circuit, heat above 80°C, or incinerate. The battery
may explode
