RIBBON SAVE DEVICE, cont'd.
Transfer Ribbons
General Purpose (GP) ribbons are coated with a wax-based “ink”
that is more subject to smearing than the wax/resin-based “ink” of
High Performance (HP) ribbons. Certain combinations of GP
ribbons and thick and/or coarse receiving paper in connection with
Ribbon Save may result in a somewhat smudged printout quality.
As a possible remedy, a change to HP ribbons is recommended.
In printers fitted with a ribbon save device, the label stop/black mark
sensor (LSS) is laterally adjusted by means of a screw protruding
through the outer lower gable. Turning the screw clockwise will
move the LSS inwards and vice versa. The position of the LSS in
relation to the paper is best checked by looking head on into the print
unit when the printhead is lifted. Align the centrepoint of the V-
shaped upper sensor with the centre of the gaps to be detected.
The linear markings on the lower guide plate can also be used for
positioning of the LSS as they are spaced with an interval of exactly
1 cm (0.39") from the edge that guides the paper. This method is
especially useful for black marks (measure the lateral position of the
black marks with a ruler).
