Important Notes On Charging The Battery
• The battery fast-charge is initiated each time the power adapter is connected to the printer.
• The fast-charge controller checks the battery’s voltage and temperature, before the start of the fast
recharge process. If the battery voltage or the temperature is outside of the fast-charge limits, the
charger defaults to trickle charge at C/10 or 70mA rate.
• An optional external charger is also available.
Verifying Battery Charge State
Follow these steps to identify and correct any battery power problem encountered. It is strongly recommended
testing all printers before returning to Printek. 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. The output should be 10VDC.
1. Press the OFF switch and wait until all indicators are off.
2. Insert the AC adaptor plug into the printer. If the amber battery indicator goes on and remains on, the
battery is not fully charged, but the charge circuit is functioning. If the indicator goes on and then
turns off after a few seconds, the battery is already fully charged. In either case, the AC power portion
of the circuit appears to be ok.
3. Press and hold the FEED switch, then press and release the ON switch.
4. The printer will print a “self test” receipt. If the self- test receipt is printed, the DC power is ok.
5. Press OFF and wait until all the indicators are off.
If the amber indicator 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 indicator will go off.
