Printhead Cleaning
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. 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:
NEVER use a sharp object on the Printhead; damage can result.
Preliminary Cleaning Steps:
1. Stop printing. Raise the cover, unlatch and raise the Printhead Assembly . Wait a
minute for the printhead to cool.
2. Remove media and ribbon from the printer then proceed according to your cleaning
requirements:
