Getting Started
Please familiarize yourself with the features of your printer as shown in the following diagram. Each printer
includes a battery cartridge, a belt loop system, and one roll of receipt paper.
Battery and Safety Information
• A 7.4 Volt 2200mAH Li-Ion battery cartridge powers the printer.
• Charging time in the printer is approximately 180 minutes.
• Take the battery out of the printer when storing the printer for long periods of time.
Printer Features
3
Getting Started
• The recommended room temperature for charging is between 68°F (20°C) to 77°F (25°C).
• The battery storage temperature is 40°-104°F (4°-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.
• 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.
Caution: Do not disassemble, short circuit, heat above 80°C, or incinerate. The battery may explode.
Battery Disposal
Only dispose of used batteries according to your local regulations. If you do not know your local
regulations, the Rechargeable Battery Recycling Corporation (RBRC) is a non-profit organization
created to promote recycling of rechargeable batteries. For more information visit
www.rbrc.org.

Printer Maintenance and Troubleshooting
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 supply door by placing your fingers under the “T” pull-handle and pulling up firmly.
• Remove the paper supply roll.
• Use a print head cleaning pen (Printek 91393) and clean the print head. If a cleaning pen is not
available, use a cotton swab moistened with isopropyl alcohol.
• Clean the platen roller located on the paper supply door with a dry cloth or small brush. You can also
use the print head cleaning pen. Turn the platen roller with your finger and run the pen or dry cloth
across it. Make sure the platen roller is clean all the way around.
• Use the cleaning pen to clean the black mark sensor on the print head to remove any build-up.
• Clean the tear bar to remove any build-up.
• If the printer has a magnetic card reader installed, clean it using a MCR Cleaning Card (Printek
91394).
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.
Charging The Printer Battery
The printer battery may be charged using either an AC adapter or a DC in-vehicle adapter. Follow these steps
to charge the battery pack:
1. Plug the power adapter into an appropriate wall socket; then plug the power adapter cord into the
power connector on the side of the printer.
2. The yellow Charge indicator will illuminate to show the battery is charging.
3. The Charge indicator turns off when battery cartridge is fully charged. It takes up to 180 minutes to
fast charge the battery pack.
4. To insure full charge, printer should not be operated while the battery is charging.
19
Printer Maintenance and Troubleshooting
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.
