2.1.1 Cleaning the Printhead
CAUTION
NEVER use a sharp object to clean the Printhead; damage can result.
If print quality declines (symptoms can include non-compliant bar codes, print dropouts,
streaks on the label), the typical cause is debris build-up on the printhead. Furthermore, if
the build-up is not removed it may lead to element failure, greatly reducing the life of the
printhead.
Faulty Label:
Instead of consistent patterns, streaks in the print
indicate a dirty or faulty printhead.
According to the media, ribbon, and printing parameters used, different methods are
recommended for cleaning the printhead. In all cases, perform the following preliminary
operations:
Preliminary Cleaning Steps:
1. Stop printing. Raise the cover, unlock the Printhead Latch then raise the Printhead
Assembly and allow the printhead to cool.
2. Remove media and ribbon from the printer then proceed according to your cleaning
requirements.
