Chapter 7 Transfer Ribbon Mechanism
7.3 Ribbon Rewind
Unit
The ribbon rewind unit 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 using two
#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.
