4. Printer Maintenance
4.1 Cleaning:
You may need to clean the print head and platen roller after printing a number of
rolls of paper, whenever you load new supplies or when you see voids in the
printout.
!
Caution: Do not use sharp objects to clean the print head. This may
damage the printer and require service.
Open the paper door by pulling the “T” bar lever on the top cover as shown
in Figure 3. 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: You can also use another cotton swab moistened with isopropyl
alcohol. 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 any build-up
Moisten another cotton swab and rub the swab across the tear bar to remove
any build-up
Note: You may experience dust build-up depending on the environment
and the quality of the paper supply you use. If this occurs, use a can of
compressed air to blow dust and paper debris out of the printer.
4.2 Charging the Printer Battery:
The printer battery is charged using the wall mounted charger provided. Follow
these steps to charge the battery pack.
Plug the charger into an appropriate wall socket; then plug the charger line
cord into the adapter jack on the side of the printer (see Figure 3)
The yellow CHARGE LED will illuminate, to indicate battery is charging
The Charge LED turns off when battery cartridge is fully charged. It takes
about 180 minutes to fast charge the battery cartridge
To insure full charge, printer should not be operated while the battery is
charging.

The model S3750THS printers require an adaptor output of 10VDC/1.4A.
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 Extech batteries
