Intermec EasyCoder 501 XP – Service Manual Ed. 4
Description
The ribbon supply unit is used to accommodate the fresh supply of
thermal transfer ribbon. Only original transfer ribbon from Inter-
mec 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 hub is fi tted. The hub can pivot ± 1.3º on the shaft
and the hub can be moved sideways.
Adjustment
It is most important for avoiding ribbon wrinkling that the pivoting
point of the hub is centered in relation to the ribbon width. There-
fore, the shaft is provided with six grooves which correspond to
the standard widths of Intermec transfer ribbons (see table to the
left.) The three innermost grooves are used with EasyCoder 501
XP, whereas the three outermost grooves only are used with the
wider EasyCoder 601 XP. By compressing the hub, 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 hub without compress-
ing it.
Ribbons with a width less than 60 mm (2.36 inches) can be used
provided they are wound on a core with a width of at least 45 mm
(1.77 inches.)
