5.3.1

Replacing the Platen Roller

The printer's platen roller is considered a high-wear component due to constant treading of the print
media and ribbon stock against its contact surface. This constant contact will eventually wear grooves
into the rubber material and negatively affect print output.
You can easily remove and replace a damaged or worn platen roller.
Required tool:
• Phillips screwdriver

CAUTION
• The print head and its surroundings are hot after

burned.
