Description
The ribbon rewind unit is the same for EasyCoder 501 XP and
EasyCoder 601 XP. It pulls the transfer ribbon around the print-
head and winds it up on a cardboard core. The unit is driven via a
belt by the same stepper motor that drives the platen roller.
The rewind unit is provided with a friction brake and a ratchet gear
wheel in order to keep the ribbon tight.
The ribbon rewind unit is fi tted to the center section usingtwo #T20
Torx screws inserted from the electronics compartment. One of
the screws runs in a crescent-shaped slot to allow adjustment or
removal of the belt.

ers at the outer end of the shaft and should be adjusted to 160±10
