•
Do not use hard, sharp or abrasive objects to remove residue from the
printhead.

on the packaging.

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.
1. 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.
2. 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
