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
using cleaning cards or a cotton swab moistened with isopropyl alcohol,
preferably each time you load a new supply of transfer ribbon.
Isopropyl alcohol [(CH
3
)
2
CHOH; CAS 67-63-0] is a highly
flammable, moderately toxic, and mildly irritating sub-
stance.
1 Open the side door.
2 Remove the media and ribbon.
3 Lift the printhead by pulling out the printhead lever and flipping it
counterclockwise a quarter of a turn.
4 Use a cleaning card or a soft cotton swab moistened with isopropyl
alcohol to dissolve any contamination at line of heat-emitting dots at
the front/bottom edge of the printhead.
5 After approximately 30 seconds, carefully rub off any contamination.
Repeat if necessary.
Never use any hard or sharp tools to peel away stuck labels
or similar. The printhead is delicate and can easily be dam-
aged.
6 Allow the printhead to dry for a minute or so before loading a new
supply of media and ribbon.
