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.
WARNING
• Do not touch the power button, connect or disconnect the power cord while your hands are wet. Doing so
could cause an electric shock.
• Disconnect the power cord from the AC outlet before you replace the platen roller.
1 Make sure that the printer is in power off
mode, then disconnect the power cord
from the AC outlet.
2 Open the top cover.
CAUTION
Open the top cover fully to prevent accidental drop of
the cover.
3 Push the head lock lever . towards the
rear to unlock the print head.
CAUTION
• The print head and its surroundings are hot after
printing. Be careful not to touch it, to avoid being
burned.
• Touching the edge of the print head with your bare
hand could cause injury.
