Internal Rewinder
Measurement of the winding torque at the internal rewinder occurs by determining the pulling forces with a cord
wrapped around the rewinder.
The physical relation between the torque and the pulling force is:
F= M / r
F:
Pulling force [N],
M:
Winding torque [Ncm],
r:
Radius of the rewinder (38 mm)
The set values for the winding torque and the resulting pulling force at the rewinder are:

Danger!
Risk of death via electric shock!
Before opening the housing cover, disconnect the device from the mains supply and wait at least one
minute until the power supply unit has discharged.
1. Unplug the printer from the electrical outlet.
2. Remove cover
3. Remove the labels from the printer.
4. Push the cord under a bracket (2) of the internal rewinder (3) and wind it around the rewinder (4).
5. Secure spring scale [10 N] (1) at the end of the cord.
6. Move the spring scale upward vertically until the winder begins turning. If the drive belt at the rewinder is also
moving, hold it in place during the measurement. Otherwise, the measurement is not accurate.
7. Allow the cord to unwind from the rewinder at least one full turn and read the pulling force F on the spring scale at
the same time.
8. If the winding torque differs from the set value, it must be adjusted 5.1.2 on page 21.
