Description
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 print 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 fitted to the centre-line wall by means of
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.
Adjustment
The braking torque can be adjusted by adding or removing washers
at the outer end of the shaft and should be adjusted to 215±20 Nmm
