Ribbon Rewinder Belt
The belt should be adjusted so it neither jump the cogs nor becomes
subjected to unnecessary wear.
Before adjusting this belt, check the tension of the pressing roller
belt as described on the previous page.
Slightly loosen the two #T20 Torx screws that hold the flange of the
ribbon rewind unit.
Turn the ribbon rewind unit so the belt becomes tight, yet will flex
slightly when you press it with a finger. Tighten the screws.
Check that the parts can rotate freely and without any unpleasant
sound and that the belt does not jump the cogs when you rotate the
ribbon rewind unit forcefully.
The ribbon return roller should be easy to rotate manually. Once the
motor starts, the belt will be tight and will drive the ribbon return
roller.
If the idler roller starts to squeak, lubricate the inside of the belt with
a small quantity of grease.
