Cleaning the Platen Roller
Dirt and debris on the platen roller can make the roller feed
paper into the printer at an angle, degrade the quality of the
printed image, or both.
1. Make sure the printer is powered on without paper
loaded.
NOTE: If paper is loaded and detected printer when you
attempt to initiate Cleaning Mode, a Form Feed will be
executed instead.
2. Press the main switch for about two seconds. The “Data”
LED will illuminate.
3. Press the main switch again for less than 2 seconds. The
feed motor will begin to turn.
4. Insert the black cleaning cloth that came with the
printer into the printer’s paper input slot with the
rough black side, which contains the cleaning
material, towards the front of the printer. See Figure
18. The printer pulls the Cleaning Cloth through.
5. The roller movement will stop automatically after about
60 seconds, and the printer returns to an idle state. If you
press the main switch before 60 seconds has elapsed, this
will toggle the feed motor on and off. Pressing the main
switch twice quickly will shut off the printer.
