The belt should be adjusted so it neither jump the cogs nor becomes sub-
ject to unnecessary wear.
Before adjusting this belt, check the tension of the platen roller belt as
described on the previous page.
Slightly loosen the two #T20 Torx screws that hold the fl ange of the
ribbon rewind unit.
Turn the ribbon rewind unit so the belt becomes tight, yet will fl ex slightly
when you press it with a fi nger. 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 assist roller.
If the idler roller starts to squeak, lubricate the inside of the belt with a
small quantity of grease.
