When printing narrow label stock (width less than 60% of the maximum print
width), it is possible that the printhead will come into direct contact with the
printing roller in the area where there is no media.
CAUTION !
The printhead touching the printing roller could lead to premature failure
on the printhead or the print roller!
This can also cause the printhead to be at a slight angle to the media, leading
to a variation in the darkness of the print across the label.
This fault can be corrected by adjusting the printhead support :
Adjustment of the Printhead Support
7. Media Loading
1. The current position of the printhead support (2) is shown by the position
of the screw (3) in the elongated hole (4).
2. For wide media the screw position shown in figure 7h is recommended. In
this position the printhead support (2) is not used.
3. For narrow media, it is necessary to adjust the printhead support. In this
case insert a second strip of a label at the outer side of the print roller and
close the printhead. Loosen the screw (3) using the Allen key (5) and slide
it slowly in the arrow direction until the printhead support (2) touches the
printhead mounting (1).
4. Tighten the screw (3).
5. Remove the second label strip.
NOTICE !
Incorrect adjustments of the printhead support may cause wrinkles in the
transfer ribbon.
