Cleaning the Printer Covers
Use a general purpose cleaner (soapy water/mild detergent) to clean the
printer covers. Do not use abrasive cleansers or solvents. Be sure to clean
the transparent panel on the media cover so that the media supply inside
the printer is visible when you close the cover.
Cleaning the Drive Roller and Tear Bar
Cleaning the drive roller and tear bar preserves print quality by
maintaining close contact between the media and the printhead.
To clean the drive roller and tear bar
1 Turn the On/Off switch to the off position and remove the power cord.
2 Remove the media cover.
3 Rotate the head lift lever clockwise to release the printhead.
4 Remove the media and ribbon (if necessary).
5 Clean the drive roller by using a cloth dampened with isopropyl alcohol.
Move the cloth over the drive roller in a side-to-side motion as shown.
Make sure to rotate the roller so that you can clean all areas.
Note: Rotating the TTR assist roller toward you enables you to clean
the entire drive roller surface.
