Application Roller Position; Sensor Calibration - Primera AP550e Operator's Manual

3.3 Application Roller Position

r-1: The default Application Roller Position is r-1 which is the position furthest from the peel
edge. The r-1 position is the most forgiving for container surfaces that are not completely flat.
It also works with the widest variety of container heights.
r-2: The r-2 position should be used if you are using a shorter label that does not reach the
Application Roller before falling off the liner. The label should always extend underneath the
Application Roller so that the roller will press the leading edge of the label to the container
when the arm is lowered.
To adjust the physical position of the Application Roller, remove the thumb screws on either
side of the Application Arm. Push or pull the roller to align the thumb screw holes with the
desired holes in the side plates. (The r-1 holes are closer to the front of the unit than the r-2
holes.) Replace the thumb screws.
Note: Make sure the physical position of the Application Roller always matches the setting selected.

3.4 Sensor Calibration

The Label Sensor must be calibrated to the specific label stock being used for each memory
location. Use the following procedure to calibrate the applicator for your specific label stock/
liner material:
1. Load the label stock as described in Section 2. Be sure to remove labels from the liner back
to the Liner Drive Roller. For reflective stock, the black mark should be positioned directly
under the Label Guide Roller. The goal is to feed only clean liner through the sensor area.
This will give the sensor a good reading of the liner material.
2. Once the liner is loaded, follow the steps above to navigate to the SC- setting in the
Setup Mode.
3. Lower the arm to trigger the calibration.
4. The label stock will
move forward until the
first label is presented
for application.
5. Calibration for this liner
is now complete and
the values are stored
in the current memory
location.
Note: It is not necessary to
recalibrate the label sensor
between rolls of the same label
stock.
For reflective stock, the black mark For reflective stock, the black mark
should be positioned directly under this should be positioned directly under this
