Cleaning The Printhead - Datamax M-Class Mark II Maintenance Manual

2.1.1 Cleaning the Printhead

NEVER use a sharp object to clean the Printhead; damage can result.
CAUTION
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.
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.
Adjustments and Maintenance
Faulty Label:
Instead of consistent patterns, streaks in the print
indicate a dirty or faulty printhead.
