5.3.1

Cleaning the Printhead

If print quality declines (symptoms include non-compliant bar codes, print
dropouts, streaks; see Section 4.3.4), 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 life of the printhead. To clean the printhead:

Turn ‘Off’ and unplug the printer.

•

Open the access cover. Unlock the Printhead Latch and raise the Printhead

Assembly. Move media and ribbon away from the printhead as necessary.

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.

•

Replace the ribbon and media. Lower the Printhead Assembly and rotate the

Printhead Latch completely back, to the locked position.

•

Close the cover. Plug in and turn ‘On’ the printer. Feed several labels to

normalize tracking.

CAUTION

NEVER use a sharp object to clean the Printhead.
