Overview
The standard platen (drive roller) typically does not require cleaning. Paper and liner dust can accumulate without affecting print operations. However, if contamination on the platen roller causes the media to slip or stick when printing, you may have to perform a periodic cleaning.
| NOTE Adhesive, dirt, oils, and other residual contaminates should be cleaned off the platen immediately. |
Cleaning Platen
Clean the platen (and media path) whenever the printer has resulted in poorer performance, print quality, or media handling.
The platen is the print surface and drives the roller for your media. If sticking or jamming continues after cleaning, you 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 (99.7% pure).
