5.5.1 Cleaning the Printhead
When print quality begins to decline (indicated by symptoms including non-
compliant bar codes, print dropouts, and streaking), the typical cause is debris
build-up on the printhead (see Section 4.3.4). Furthermore, if this build-up is not
removed it may lead to premature element failures, 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 as necessary.
Gently wipe away all surface build-up on the Printhead (see below) using a
cotton swab moistened, not soaked, with isopropyl alcohol. Allow the
printhead to dry.
Re-install ribbon and media, if removed. Lower and rotate the Printhead
Latch 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.
