2.4.1 Cleaning the Printhead
CAUTION
NEVER use a sharp object to clean the Printhead.
If print quality declines (symptoms can include unreadable bar codes, or streaks through the text and
graphics), the typical cause is debris build-up on the printhead. Furthermore, if not removed, this build-up
may lead to premature dot failure. Clean the printhead every time a roll of ribbon has been used. If using
direct thermal stock, clean the printhead every time a roll of labels has been used, or as needed. To help
you remember this important maintenance procedure, the printer can be programmed to prompt you for
cleaning; see the
Operator’s Manual
for details.
Faulty Label:
Instead of consistent patterns, streaks in the direction
of print indicate a dirty or faulty 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:
 Stop printing. Raise the cover, unlock the Printhead Latch and raise the Printhead Assembly.
Wait
for the printhead to cool.

Remove media and ribbon from the printer.
Proceed according to your cleaning requirements.
