Adjusting The Cylinder Extend Time - Printronix SLPA7000 User Manual

Printing And Applying Labels
4. Place the product sample on the conveyor and allow it move past the
SLPA. The label that is applied will be used as a reference point for
positioning the rest of the labels.
5. To move the label toward the leading edge of the product, decrease the
Cycle Delay time. Begin by decreasing the time in intervals of 10 msec,
then fine tune in intervals 1 msec. Repeat this procedure until the label is
positioned where desired.
6. To move the label toward the trailing edge of the product, increase the
Cycle Delay time. Begin by increasing the time in intervals of 10 msec,
then fine tune in intervals 1 msec. Repeat this procedure until the label is
positioned where desired.
If the label still cannot be positioned properly, remount the product sensor as
follows:
1. To position the label toward the leading edge of the product, move the
product sensor upstream.
2. To position the label toward the trailing edge of the product, move the
product sensor downstream.
3. Once the label is positioned in the desired location on the product, secure
the product sensor onto the conveyor.
If the SLPA cycles when a product is not in position, a background object may
be activating the sensor. To correct this problem, reposition the product
sensor or adjust the product sensor. See "Product Sensor" on page 331 for
more information on product sensor adjustments.
WARNING
Interrupting the signal on the product sensor will activate the SLPA.
Make certain that the path of the applicator path is clear.

Adjusting The Cylinder Extend Time

1. Set the Cylinder Extend time using the Applicator Delay menu. (See
"Applicator Delay Menu" on page 152.)

cylinder extend time, determines how far the pad travels during
application of the label. The longer the time entered, the farther the
distance the applicator pad travels. If this value is set to zero, for
example, the applicator pad will not launch.
Set the Cylinder Extend time to 110 msec to begin this adjustment
procedure.
Increase the Cylinder Extend time using the Applicator Delay menu.
Begin by increasing the time in intervals of 6 msec, then fine tune in
increments of 1 msec. A higher setting allows the applicator pad more
time to extend toward the product, therefore, increasing the stroke
length.
