The supporting air from the blow tube is not immediately switched on
at print start but only if the label has covered a distance.
This delay helps to prevent a turning or swinging at the front of the
label and consequently avoids faults when the label is being picked up
from printer.
Value range: 0 … 2500 ms
Step size: 0 ms
Default: 0 ms
Delayed to the process of the label being picked up, the supporting air
is switched off.
In many cases, after being picked up by the pad the label edge may
still stick on the liner. This may affect the accuracy of the label
positioning or even cause faults in the labelling. Therefore, switching
off the air blow delayed can be useful to separate the label from liner
and neatly place the label on the surface of pad.
Value range: 0 … 2500 ms
Step size: 10 ms
Default: 500 ms
With activated compressed air control, with help from a compressed
air sensor it is checked at each labelling cycle if the compressed air
fits with the valve block. If no compressed air is presented, the
labelling cycle is stopped and the error message 'compressed air' is
displayed.
If the parameter 'pressure control' is set to Off, the error treatment as
described above will not be effected. This can be especially helpful at
initiation of the labelling system.
For standard operation, set the parameter to On.
The label transfer from printer to applicator is controlled by a vacuum
sensor. If the transfer of label fails, the sucking holes on the pad will
not be covered by the label and therefore no vacuum can originate on
the pad. Afterwards an error message appears and the label strip will
be fed back.
If the parameter 'vacuum control' is set to Off, the error treatment as
described above will not be effected. This can be especially helpful
during adjustments, because the immediate backfeed will be
cancelled and therefore it is easier to check the reasons for the faulty
transfer.
For standard operation, set the parameter to On.
This parameter is only active if the operating mode 'stamp on' is
selected. The time period can be adjusted while the stamp is kept in
the labelling position for applying the label onto the goods.
