Drive Roller
After prolonged use, the drive roller and the rubber pressure roller above it may
wear. This will impede the smooth exit of label stock. When this occurs, the
roller requires replacement.
TO REPLACE THE DRIVE ROLLER:
1. Turn the printer off and unplug it. Open the printer cover.
2. Remove any label stock that may be exiting over the drive roller.
3. Flip the drive roller cam up to relieve pressure on the roller and open it, but
do not lock into the open position.
4. Press down the silver clip holding the cam, pull the cam completely out, and
set it aside.
