Chapter 3 — Troubleshooting and Maintaining the PB21 and PB31
60 PB21 and PB31 Mobile Receipt Printer User Guide
Resetting the Printer
You rarely need to reset the printer, unless you are upgrading the
firmware. If your printer occasionally locks up, you will want to reset
it. A reset reinitializes the 802.11 radio and clears the working
memory.
To reset the printer
1 Disconnect the printer from power if externally powered.
2 Remove the battery from the printer for at least one second.
3 Insert the battery back into the printer.
4 Reconnect external power if your printer is externally powered.
Cleaning the Printer
To properly maintain your printer, you must clean it at the
recommended interval. Use the next illustration to locate the parts of
your printer to clean.
Make sure to clean these parts:
• Printhead
• Platen roller
• Paper sensors
• Tear bar
• Printer exterior
• Media compartment
Note: The Setup menu is not affected by a reset. Your printer retains
all of your configuration settings after the printer powers back up.
To avoid possible personal injury or damage to the printer,
never insert any pointed or sharp objects into the printer.
