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 internal rewinder (20 mm)
The set values for the winding torque and the resulting pulling force at the test collar are:
Slipping clutch on Direction of rotation Printer Winding torque M Pulling force F
Internal rewinder clockwise A2+, A4+, A4.3+, A6+ 28 - 32 Ncm 14 - 16 N
counterclockwise A2+, A4+, A4.3+, A6+ 8 - 12 Ncm 4 - 6 N

Danger!
Risk of death via electric shock!
Before opening the housing cover, disconnect the device from the mains supply and wait at lease one
minute until the power supply unit has discharged.

Unplug the printer from the electrical outlet.
Remove the rear cover.
Remove the label media from the printer.
Push the cord (2) under a bracket of the internal
rewinder (3) and wind it around the rewinder.
Secure spring scale [25 N] (1) at the end of the cord.
Move the spring scale (1) upward vertically until the
winder begins turning.
If the drive belt is also moving, hold it in place during
the measurement. Otherwise, the measurement is
not accurate.
Allow the cord to unwind from the test collar at least
one full turn and read the pulling force F on the
spring scale at the same time.
Determine the pulling force in the same manner,
except in the opposite rotation direction (4).
If the winding torque differs from the setpoint, it must
be adjusted
