Platen Cleaning and Replacement
The standard platen (drive roller) normally does not require cleaning. Paper and liner dust can
accumulate without effecting print operations. Contaminates on the platen roller can damage
the printhead or cause the media to slip or stick when printing. Adhesive, dirt, general dust,
oils and other contaminates should be cleaned immediately off the platen.
Clean the platen (and media path) whenever the printer has significantly poorer performance,
print quality or media handling. The platen is the print surface and drive roller for your media.
If sticking or jamming continues even after cleaning, y ou must replace the platen.
The platen can be cleaned with a fiber-free swab (such as a Texpad swab) or a lint free, clean,
damp cloth very lightly moistened with medical grade alcohol (90% pure or better).
1. Open the cover (and dispenser door). Remove media from platen area.
2. Pull the platen bearing latch release tabs on the right and left sides towards the front of the
printer and rotate them up.
