11.5 LABEL PRINTING WITH THE OPERATION OF A WINDER

Depending on the version, a paper winder can be connected to the GCT-4663 controller.
The winder serves to wind up the backing paper and to maintain the tension needed to peel off the labels.
If a printout is to be triggered, the winder must first tension the backing paper, so that a following label can be detached in
any case. This lead time is set with

parameter 23,10

in [ms]. If the paper is still taut as a result of a previous print, since

the winder is still in operation, this time is not executed. During printing, the winder always has to run a little "faster" than
the printer so that the tension remains. The speed differences are compensated by a friction clutch, set by

parameters

23,3 and 23,4

. The

parameters 23,5 – 23,7

need not be changed.

Parameter 23,2

defines the distance from the peeler edge to the start of the next label "ToF".

The peeling process can be monitored by the "picking" sensor. To do this, the sensor must be selected via

parameter 24,9

If the

parameter 24,5

is activated ("T"), the printer places the label after the peeler edge and immediately pulls the

following label back to the ToF position.
If

parameter 24,5

is deactivated ("F"), the printer does not pull back the paper. The locked backfeed must be set at the end

of the ticket data. This is then executed as soon as the "picking" sensor is released.
Since the printer can not pull the backing paper back against the winder, the winder must run backwards at the right time
to allow this. The winder first runs backwards the set time in [ms] (

parameter 23,11

) to run ahead the printer. Afterwards,

the winder runs backwards in parallel mode to the printer for the set time in

parameter 23,12

in [ms] in order not to "block"

the printer.
After the printer is back to the ToF position, the winder runs forward in [ms] by the time set in

parameter 23,13

to wind up

the backing paper. Thereafter, the tension is maintained for the time in [ms] set in

parameter 23,9

11.5.1 PARAMETER SETTINGS

Parameter 23,1

feed length ToF to picking sensor [decimillimeter]

This parameter sets the mechanical distance from the first print position (ToF) to the „picking“ sensor. If the sensor does
not detect the label within this length, an error condition is generated. The value should therefore be chosen slightly larger
than the physical distance (default: 500). The „picking“ sensor is selected with

parameter 24,9

Parameter 23,2

feed length ToF to peeler edge [decimillimeter]

This parameter sets the mechanical distance from the first print position (ToF) to the peeler edge. The value should
correspond to the mechanical distance. If the value is too small, the printer will not cast off the label completely behind
the peeler edge. If the value is too large, the follow-up label can "retrieve" the current once again.
If this value is 0, then no reversing operation is carried out. Otherwise, the reversing operation is performed by this value.

Parameter 23,3

winder motor start speed [PPS]

Start speed of the winder motor (default 300)

Parameter 23,4

winder motor final speed [PPS]

Final speed of the winder motor (default 800)

Parameter 23,5

number of winder motor speedup stages

Speedup stages of the winder motor (default 4)

Parameter 23,6

microstep resolution of the winder motor

Microstep resolution of the winder motor, range 1...8, (default 8 )
