Cleaning The Printhead, Platen Roller And Media
Sensors
NOTE: You do not need to turn off the printer before cleaning the printhead,
Printhead Cleaning
As you use your printer, the printhead may become dirty which can result in
poor print quality. Clean the printhead each time you install new ribbon
(thermal transfer print mode) or install new media (direct thermal print mode).
Clean the printhead with a cotton swab and isopropyl alcohol supplied with
the printer.
By keeping your printhead clean, you will help maintain its life.
Platen Roller Cleaning
Media dust and adhesive residue on the platen roller can degrade print quality
and cause voids in your label image. Clean the platen roller at the same time
as the printhead.
Use a small amount of isopropyl alcohol on the cloth supplied with your printer
to clean the platen roller. With the pivoting deck open, the platen roller can be
rotated forward by hand to access and clean its entire surface area.
Media Sensor Cleaning
CAUTION
Do not use isopropyl alcohol, solvents, or abrasive agents to clean the
media sensors. They can damage sensor lens covers.
The lower media sensor should be cleaned to ensure reliable TOF and Paper
Out sensing. Clean the media sensor at the same time as the printhead.
The lower media sensor can be wiped clean using a soft cloth. Remove media
dust by vacuuming or blowing air across the lens cover.
