Cleaning the Printhead
Cleaning the printhead on a regular basis prolongs the life of the
printhead and ensures you maintain high printout quality. You
should clean the printhead with cleaning cards or a cotton swab
moistened with isopropyl alcohol. Ideally, you should do this
every time you load a new supply of transfer ribbon.
To clean the printhead
1 Open the side door.
2 Remove the media and ribbon.
3 Pull out the printhead lever and flip it counterclockwise a
quarter of turn.
4
Use a cleaning card or a soft cotton swab moistened with
isopropyl alcohol to dissolve any contamination on the line of
heat-emitting dots at the front/bottom of the printhead.
5
Wait 30 seconds and carefully rub off any contamination.
Repeat if necessary.
6 Allow the printhead to dry for a minute or more before
loading a new supply of media and ribbon.
Isopropyl alcohol [(CH

)

CHOH] is a highly flammable,
moderately toxic, and mildly irritating substance.
Never use any hard or sharp tools to peel away stuck labels
or similar,. The printhead is delicate and can easily be
damaged.
