Fig. 7 b Adjustment of the printhead support
When printing narrow labels (width less than 2.5 in 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, thus, the 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 (2) may be adjusted.
Adjust printhead support as follows :
1. Loosen the locking screw (2). For Apollo 1, this screw is an oval-headed
screw, whereas for Apollo 2/3 it is a knurled screw.
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.
As the adjustment criterion, check the quality of the print image.
3. Tighten the locking screw (2).
NOTICE !
Incorrect adjustments of the printhead support may cause wrinkles in the
transfer ribbon.
