Measuring the torque of the clutch and brake on the ribbon rewind hub:
1. Wind the cord several times round the tape holder on the rewind hub (1) (see fig. 14 A).
2. Attach a spring scale [20 N] (2) to the end of the cord, raise it vertically until the holder starts to turn.
3. Allow the cord to unwind at least one full turn from the holder, and read off the traction F for the clutch
on the spring scale.
4. Reset the winding torque of the clutch if it differs from the specified value (see section 3.2 on
page 23.)
5. Disconnect the rewind hub (1) from the drive in order to measure the winding torque for the brake.
Press the release button, hinge up the printhead assembly, repeat the measuring procedure
(see fig. 14B.)
6. If the winding torque of the brake differs from the specified value, the parts involved must be
replaced, they cannot be reset.
Measuring the torque of the clutch on the ribbon supply hub:
1. Wind the cord several times round the tape holder on the supply hub (3) (see fig. 14 C).
2. Measure the winding torque for the clutch of the supply hub, and set it in the same way as on the
