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.

2. The yellow Charge indicator will illuminate to show the battery is charging.

fast charge the battery pack.
4. To insure full charge, printer should not be operated while the battery is charging.
