Maintenance and Adjustment
6.3 Adjusting the print line
You can adjust the ribbon tension by
turning the ribbon shaft knob (green
wheel at the base of the ribbon
supply hub – see illustration)
clockwise or anticlockwise. There are
4 possible settings, which are marked
on the knob of the ribbon rewind
hub and the ribbon supply hub.
When set to 1, the tension is highest,
while the tension is lowest at 4. If the
tension is so low that the ribbon does
not move forward, you need to
reduce the tension of the ribbon
supply hub or increase the tension of
the ribbon rewind hub. To set the
tension, press in the knob and turn it
clockwise or anticlockwise as
required.
Increasing the tension of the ribbon
rewind hub will remove any wrinkling
of the ribbon during printing, which
results from the use of different
ribbon materials. (For details about
the wrinkling/creasing of ribbons, see
Section 5-6.)
If you are using a very narrow ribbon,
the printer may not move the label
stock forward (particularly with a
ribbon that is less than 2" wide). In
that case, reduce the tension by
turning the knob of the ribbon supply
hub anticlockwise. If the tension is
too high, the ribbon core may be
crushed and thus impossible to
remove. In that case, reduce the
tension of the ribbon supply hub and
the ribbon rewind hub by turning the
knobs anticlockwise.
