Cleaning the Printhead
If print quality declines (e.g., non-compliant bar codes, print dropouts, or
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:
n
Turn ‘Off’ and unplug the printer.
o
Open the access cover. Unlock the Printhead Latch and raise the Printhead
Assembly. Move media and ribbon away from the printhead as necessary.
p
Gently wipe off all debris build-up on the Printhead surface, paying close
attention to the burn line, using a cotton swab moistened, not soaked, with
isopropyl alcohol. Allow the printhead to dry.
q
Replace the ribbon and media. Lower and rotate the Printhead Latch to the
locked position.
r
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.
