Suppressing start signals
The shape of the product or reflecting surfaces can
cause a premature start signal, which will result in in-
correct labelling. Start signals can therefore be ignored
in cases such as these, while the product is being
moved along under the dispensing edge. Function
LABEL SETUP > Product length must be set to the product
length for this purpose.
Example:
When the product [82D] reaches the product
sensor [82C], a start signal is generated and the ma-
chine dispenses a label. The recesses in the product
generate additional start signals, which could cause the
product to be labelled more than once. The product
length setting [82A] in function LABEL SETUP >
Product length causes the machine to ignore all start sig-
nals until the product has passed the dispensing head.
Label position on the product
Requirements:
• Label length is set
• Label stop position is set
• Setting in dispensing mode:
 Set the start delay (also called start offset) with the
two right keys (see Online settings  on page 39).
Or:
 Open LABEL SETUP > Start offset and set the start de-
lay.
The label should be flush with the front of the product:
 Enter the distance between product sensor and dis-
pensing edge [83A].
The label should be applied at a distance from the front
of the product:
 Add the distance [84A] to the front of the product to
the value for start delay.
