Label stop position
Requirement: label pitch must be set
The next label to be dispensed is waiting in the label
stop position. It is advantageous for the label to pro-
trude a little over the dispensing edge [81].
The ALX 73x is preset for use with the label
sensor included with delivery. If this light sensor
is used, the setting of the label stop position
needs to be corrected only slightly at most.
To correct the pre-setting:
1. Open LABEL SETUP > Lab. stop offset.
2. Increase the value to increase the overhang or de-
crease the value to decrease the overhang.
CAUTION!
Mind the following setting rules to avoid a
strong decrease of dispensing accuracy:
At maximum dispensing speed set the
Lab. stop offset to at least 10 mm!
a
Don´t set Lab. stop offset to the same value
as LABEL SETUP > Label pitch (also not to a
multiple of the value).
Don´t set Lab. stop offset to „0“.
Set Lab. stop offset so that the label sensor
stands on top of the label as far as possible
away from the label edge, when the label
web stops.
a) General rule: The setting must at least equal the „brake distance“
of the label web until it stops. For high speed, this value is higher
than for low speed.

a) 19 mm = Distance [81B] between label sensor and dispensing
edge (with fixed L-shape dispensing edge).
The label stops flush with the dispen-
sing edge.
(19 mm + x) The label stops with x mm overhang.
