Adjustments, cont.
Ribbon Assist Roller (not on EasyCoder 501 LL)
The alignment of the ribbon assist roller is important for avoiding
ribbon wrinkling. The roller is factory-adjusted, but may require
additional adjustment later on.
If the ribbon becomes wrinkled, a few checks should be performed
before the ribbon assist roller is readjusted:
• Is the printhead pressure properly adjusted?
• Is the green edge guide correctly positioned?
• Is there anything that may interfere with the transfer ribbon, for
examplethe printhead cables.
If the wrinkling problem remains, proceed as follows:
• Using a #T20 Torx screwdriver, loosen the locking screw that
runs in the crescent-shaped hole in front of the headlift knob.
• Insert the #T20 Torx screwdriver through the hole immediately
below the locking screw. The key will engage cogs in the plate
that holds the outer end of the ribbon assist roller inside the
upper gable.

• By turning the Torx screwdriver, you can move the outer end of
the ribbon assist roller back and forth:
- Turn it clockwise to move the end of the roller forward.
- Turn it counterclockwise to move the end of the roller rear-
ward.
