When printing narrow label stock (width less than 2.5" or 60 mm), it is possible
that the printhead will come into direct contact with the drive roller. This will
lead to premature wear on the printhead. In addition, the printhead will be at a
slight angle to the label, and this uneven pressure may result in an inconsistent
image density from one edge of the label to the other. To correct this problem,
the printhead support (
4
) should be adjusted.
Adjust the printhead support as follows:
1. Loosen the locking screw (
2
).
2. Move the locking screw (
2
) as required within the adjustment slot (
3
). This
will cause the cam shaped printhead support (
4
) to rotate, in effect,
providing a higher or lower base on which the printhead mounting (
1
) rests.
3. When using wide labels, start with a setting of "2a"; this places the
printhead support at its' lowest position, providing the most complete
contact of the printhead to the drive roller along the entire width. When
using very narrow labels, a setting of "2b" is recommended; this places the
printhead support at its' highest position, reducing contact of the printhead
with the drive roller at the outside edge.
At the adjustment criterion, check the quality of the print image.
4. Retighten the locking screw (
2
).
