3.3 Label guide
On some of the axles, they’re guiding clamps. Adjust the clamps near the machine so all have
the same distance to the front plate (31.5mm). The outer clamps should be mounted that the
guide but not bend the label material.
The front of the V-dispensing edge has a rot, which can be adjusted for straighten the material
guiding. Spend several labels by pressing the dispenser FEED key. If the material guiding is
running out of the guiding way, adjust the rot by loosing two screws at the dispensing edge.
With a L-dispensing the adjustment is done by move the tail sheaves behind the dispensing
edge.
3.4 Adjust dispense function
For an operation without any trouble and high label accuracy, tree adjustments are required:
• Label position on the dispensing edge: stop position
• Dispense speed
• Label position on the product
The adjustment should be done in the same order, because parameter like the stop position
depends on the setting of the stop position and the dispensing speed.
3.4.1 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 6 Stop position
The stop position should be adjusted so that the label stops at the dispensing edge 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.
