Ribbon tension
To achieve an optimal print result, the
ribbon has to run without creases. This is
achieved by correctly setting the torque for
the rewinding mandrel and the braking
torque for the unwinding mandrel.
The factory settings cover a wide range of
different ribbon widths. Nevertheless,
adjustment can be necessary if very
narrow or very wide ribbons are being
used.
The braking torque of the ribbon mandrels
can be set by adjusting the red hexagonal
plastic nuts [19A] on the ribbon mandrels.
Turn clockwise to increase the torque.
Caps [19B] protect the nuts against being
adjusted by accident.
The ribbon must run evenly and free of
creases between the mandrels while being
fed through. The following indications can
help you correct the settings:
• The ribbon is slack or in folds or winds on
to the rewinding mandrel too loosely.
« Increase torque / braking torque (turn red
hex nut clockwise).
• The ribbon clearly stretches or it tears
during printing. The ribbon is not being
transported adequately.
« Decrease torque / braking torque (turn red
hex nut anti-clockwise).
