Cleaning The Printhead, Platen Roller And Media Sensors

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 or the cleaning pen
supplied with your printer to clean the platen roller. With the pivoting deck up
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
upper or lower media sensor. They can damage sensor lens covers.
The upper and lower media sensors should be cleaned to ensure reliable
TOF and Paper Out sensing. Clean the media sensors at the same time as
the printhead.
The upper media sensor (located in the horizontal slot of the printhead cover)
can be wiped clean using a soft cloth.
The lower media sensor, easily seen by its visible red light, is located in the
horizontal slot of the media guard. Remove media dust by vacuuming or
blowing air across the lens cover.
