6.1 Cleaning the Printhead
If print quality declines (symptoms include non-compliant bar codes, print dropouts, and streaks; see sample label below),
the typical cause is debris build-up on the printhead. Furthermore, when the build-up is not removed it may lead to
element failure, greatly reducing the service life of the printhead.
Faulty Print Quality Label:
Streaks indicate a dirty or faulty printhead.
To clean the printhead:
1. Turn ‘Off’ and unplug the printer.
2. Open the cover. Unlock the Printhead Latch and
raise the Printhead Assembly. Allow the printhead
to cool before proceeding.
3. Move media and ribbon away from the printhead as
necessary.
4. Using a Cotton Swab moistened, not soaked, with
isopropyl alcohol gently wipe away any build-up
on the printhead surface, paying close attention to
the Burn Line. Allow the printhead to dry.
5. Replace the ribbon and media. Lower the Printhead
Assembly back to the locked position.
6. Close the cover. Plug in and turn ‘On’ the printer.
Feed several labels to normalize tracking.
