Cleaning The Printhead - Datamax ?-class series Maintenance Manual

2.1.1

Cleaning the Printhead

NEVER use a sharp object on the Printhead; damage can result.
CAUTION
If print quality declines (symptoms can include non-compliant bar codes, print dropouts, streaks on the
labels), 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 before cleaning the
printhead:
Preliminary Cleaning Steps:
1) Stop printing. Raise the cover, unlock the Printhead Latch and raise the Printhead Assembly.
Allow the printhead to cool.
2) Remove media and ribbon from the printer.
Proceed according to your cleaning requirements.
Adjustments and Maintenance
Faulty Label:
Instead of consistent patterns, streaks in the direction
of print indicate a dirty or faulty printhead.
