CAUTION: When performing maintenance inside the printer,
always make sure that the print head is latched completely before
installing the top cover. Failure to do so may result in damage to
the print head.
10.6 Cleaning the Drive Roller
Maintaining a clean Drive Roller not only helps to extend the life of the roller but also helps
to reduce print quality issues and media slips that may occur due to dust, label adhesive
and other forms of contamination. The Drive Roller should be cleaned after every roll or 512
feet of media:
1. Remove any installed media.
2. Turn the printer power "OFF."
3. Remove the Top Cover from the printer.
