7 Adjustments Concerning the Labels
Adjustment of the Printhead Support
Fig. 7 a 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 (
4 ) may be adjusted.
Adjust 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. It is convenient to use the position 2a to printout large labels. The printhead
support ( 4 ) is total inactiv here.
4. By using small labels it is necessary to adjust the printhead support. In this
case insert a second strip of the label at the front side of the print roller.
Now slide the locking screw ( 2 ) as far as possible to position 2b in the
adjustment slot ( 3 ), until the printhead support ( 4 ) touches the printhead
mounting ( 1 ). Take away the second label strip.
5. Tighten the locking screw ( 2 ).
