The paper rewind unit is fitted to the printer's centre-line wall by
means of a flange with two ball bearing. On the inner side, there is
a gear wheel, which only can rotate in one direction due to an
internal clutch. The wheel is held by means of a circlip.
On the outer side, the bobbin and its attached gable are fitted. The
rotation is braked by means of a friction felt pad and a pressure
spring. Thereby, it is possible to rewind paper manually without
running the motor. The friction brake also takes up sudden jerks. A
bobbin plate helps to hold possible rewind cores. The assembly is
held together by a #T20 Torx screw at the end of the shaft.
If the rewind unit does not have enough strength to rewind the paper
or to peel off the labels, it may depend on the friction felt having got
dried out. Dismantle the unit and soak the felt pad in fresh motor oil.
Remove excessive oil with a piece of tissue and reassemble the unit.
The unwind torque should be 270–300 Nmm and the brake torque
15–45 Nmm
