7. Media Loading
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
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.
