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. Press the tabs on the right and left sides out. Then rotate them up.
3. Lift the platen out of the printer’s bottom frame.
4. Clean the platen with the alcohol moistened swab. Clean from the center out. Repeat this
process until the all of the roller surface has been cleaned. If there has been heavy
adhesive build-up or label jam, repeat with a new swab to remove residual contaminates.
Adhesives and oils, for example, may be thinned by the initial cleaning but not completely
removed.
