Chapter 2 Cleaning
Platen Roller Cleaning
Label parts, media dust, and adhesive residue on the platen can degrade print
quality and cause voids in your label image.
• Cleaning Agent - Use an isopropyl alcohol wipe or small amount of
isopropyl alcohol on a clean cloth to clean the platen roller.
• Schedule - Clean the platen roller each time you clean the printhead.
3. Clean the platen roller by first removing any label parts from its surface by
hand. Then use an isopropyl alcohol wipe or clean cloth moistened with
isopropyl alcohol to remove any remaining paper dust, debris, or label
adhesive. The platen roller can be rotated forward by hand to access and
clean its entire surface area.
NOTE: Even though power is removed from the platen motor, some drag will
be felt as you rotate the platen.
4. Check the platen roller for razor cuts, nicks, and gouges that may cause
voids in the printed image. This type of damage usually requires platen
roller replacement.
Media Sensor Cleaning
The upper and lower media sensors should be cleaned to ensure reliable Top
of Form and Paper Out sensing.
CAUTION Do not use isopropyl alcohol, solvents, or abrasive agents to clean the
lower media sensor as they can damage the sensors lens cover.
• Cleaning Agent - Use a brush with soft non-metallic bristles or a vacuum
cleaner, described above, to remove paper dust.
NOTE: An Isopropyl Alcohol Wipe or Printhead Cleaning Pen can be used to
remove label adhesive from the upper sensor.
• Schedule - Clean the media sensors each time you clean the printhead.
5. Brush away or vacuum any dust or debris from the upper and lower
sensor.
