Printhead Cleaning
Cleaning the printhead on a regular basis is important for the life of the
printhead and for the printout quality. You should clean the printhead
each time you replace the media. This section describes how to clean
the printhead using cleaning cards. If additional cleaning is required, for
example removing adhesive residue from the platen roller or tear bar, use
a cotton swab moistened with isopropyl alcohol.
Isopropyl alcohol [(CH

fl ammable, moderately toxic, and mildly irritating sub-
stance.
Open the front and side doors.
Turn the printhead lift lever counter-
clockwise to raise the printhead.
