Chapter 7 Transfer Ribbon Mechanism
Description
The ribbon unwind unit is used to accommodate the fresh supply of
thermal transfer ribbon. Only original transfer ribbon from UBI
must be used (else the warranty will be invalidated).
The unit is designed to keep the ribbon tight all the time in order to
avoid wrinkling, which would ruin the printout. It consists of a shaft
on which a spool is fitted. The spool can pivot
±
1.3º on the shaft and
the spool can be moved sideways.
Adjustment
It is most important for avoiding ribbon wrinkling that the pivoting
point of the spool is centred in relation to the ribbon width.
Therefore, the shaft is provided with six grooves which correspond
to the standard widths of UBI transfer ribbons (see table to the left).
Choose the groove that comes closest to the ribbon width. By
compressing the spool, its snap-lock will disengage from the
presently engaged groove and it can be moved sideways to another
position. Make sure that the snap-lock has engaged a groove by
trying to move the bobbin without compressing it.
Ribbons with a width less than 60 mm (2.36") can be used provided
they are wound on a core with a width of at least 45 mm (1.77").
