PLATEN ROLLER REPLACEMENT
The platen roller is considered to be a high wear component due to its treading against the print
media. This treading contact will eventually wear grooves into the rubber material and negatively
effect print output.

2 Remove the side cover and lower front housing cover.
3 Remove one screw (1, Figure 6-2) securing platen roller assembly (2) to printer frame (3).
