Printhead Cleaning
Clean the printhead with every ribbon change or after every 10,000 linear inches of
direct thermal label media. Use the cleaning pen supplied with the printer or a Q-tip
soaked in alcohol. Three to four swipes along the heater line should be sufficient to
remove any collected material (Figure 16)
WARNING: The printhead may be extremely HOT. Make sure the printer
is off. Using inappropriate cleaning materials will damage the printhead.
To expose the printhead, find the “ PRESS HERE ” label affixed to the Printhead
Bracket. Press down where indicated and rotate the Printhead Lock Lever back to
unlock the bracket. Swing the Printhead Bracket up and back to expose the paper
path. Leave the Printhead Bracket in the up position for cleaning the paper path.

Paper Path Cleaning
Using a lint-free cloth or compressed air, remove any dust and debris from the paper
path beneath the printhead. Return the printhead to the original position.
Remove the label roll and clean the exposed surfaces. Clear all dust and debris from
the paper guides paying close attention to the inside sensor block.
NOTE: Printers operating with high duty cycles or caustic environments
should be examined daily for dust and debris build-up.
Reinstall media, apply power and return printer to operating status.
