Cleaning the Printhead

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 3)2CHOH; CAS 67-63-0] is a highly
flammable, moderately toxic, and mildly irritating substance.
