Adjusting the dispensing position
The label, in order to be ready for pick-up by the suction plate, must be fully detached from the backing
paper. Adjust the correct position (i.e. to what extent the label is to be peeled off the backing paper
when dispensed) according to the description in section „Positioning the label“ in section 4.1.5 or 4.1.6
(pages 41 / 46).

E You have to adjust the position of the suction plate only if you use different label material.
Determine the vertical distance between dispensing plate and suction plate with the help of
eccentric bolt 7. Any variation in height with the help of the eccentric bolt you can then compensate
with stop 8 such that the distance between dispensing plate and suction plate is the same all over
the length of the suction plate. The distance, however, should be as small as possible.
To carry out adjustments with
eccentric bolt 7 you first have to loosen screw 9 on the bottom of the
unit (fig. F).

G In case of a height adjustment of the suction plate (see above) the distance covered by the cylinder
10 changes. This may require readjusting the proximity switch. This switch should respond (LED 12
(fig. H) lights up), just before (approx. 2 mm) the suction plate gets in contact with stop 8 (fig. E).
Check the switchng point of the proximity switch after any height adjustment and move the switch,
if necessary, after loosening screw 11.
