Printer Maintenance

4.1 Print Head Cleaning Instructions

The print head and platen roller may require cleaning after printing a number of rolls of paper,
when new supplies are loaded, or when voids in the printout become apparent.

require service.

The paper supply door will pop up.

Remove the paper roll.

Moisten a cotton swab with isopropyl alcohol and clean the print head.

Clean the platen roller with a dry cloth or small brush.
Note: Another cotton swab may be moistened with isopropyl alcohol in order to
clean the platen. Turn the platen roller with your finger and run the cotton swab or
dry cloth across it. Make sure the platen roller is clean all the way around.

Moisten another cotton swab with isopropyl alcohol. Rub the swab across the black mark
sensor to remove build-up.

Moisten another cotton swab and rub the swab across the tear bar to remove build-up.
Note: Dust build-up may occur depending on the environment and the quality of
the paper supply used. If this occurs, use a can of compressed air to blow dust and
paper debris out of the printer.

Important Notes on Charging Batteries


The model APEX 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 exceeds the fast-
charge limits, the charger defaults to trickle charge at C/10 or 70 mA rate.
