3.3 Dispenser Setup

For adjusting the dispenser function, set the printer to OFF.
3.3.1

Stop position

The first step is to adjust the stop position. This is the basic adjustment of the dispense
process. Also in case of problems with the machine check if the stop position is okay.
Figure 7 Stop position
The stop position should be adjusted so that the label stops at the dispensing edge or up to 3
mm behind.
For a correct operation of the automatic label compensation, they will compensate a missing
label on the web, first the distance between label sensor and dispensing edge has to be
defined. Do this by calling the DIST function in the configuration menu. Check the setting by
removing a label before the label sensor from the web. Give a start signal to the machine by
triggering the start sensor (not the FEED key) and see if the compensation is done on the right
position. Do the fine adjustment with the STOD function.
3.3.2

Fixed dispensing speed

The second step is to adjust the dispense speed. If an APSF sensor is used see 3.3.3.
If an applicator is used, the dispense speed has no influence to the dispense process. Continue
with 3.3.4.
Set POS to the distance between start sensor and dispensing edge. If installed remove the
roller to press the label onto the product. Now try to dispenser one product. If the label has
wrinkles reduce the speed VELO. If the product peels out the label, so the stop position of the
next label is before the last position increase the speed. Normally your dispense speed should
be a little bit higher then your product speed.
3.3.3

Automatic dispensing speed (APSF)

With an connected rotary encoder the dispensing speed follows the measured product speed.
To adjust the speed use the EGRA function located in the extended standard menu. The
measured speed will be displayed in the VELO function. Do the adjustment in the same way
described for fixed speed.
