4.2.1 Important Notes on Charging Batteries

The model ANDES 3 printers require an adapter output of 10VDC/1.32A.

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 70 mA rate

Optional external battery chargers are available for Datamax-O’Neil batteries. Refer to
Section 4.7 “Printer Supplies” for detailed information.
4.2.2 Important Notes on Replacing Batteries

Check for the correct Datamax-O’Neil part number for the battery and only use that
part for your new battery
Risk of explosion if battery is replaced by an incorrect type
Dispose of used batteries according to instructions in Section 4.5
4.3 Verifying Battery Charge State
We strongly recommend testing your printer before returning it to Datamax-O’Neil. 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 adapter:

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 adapter 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:
