Question
The AP360 or AP362 stops during label application.

Answer

This is caused by the label bouncing during the application process.  If the label bounces up it causes the sensor to move back to its home position at the peel edge.  If the sensor moves, the AP362 thinks the label has been applied and stops.  Try the following:

1. Push down lightly on the container pressure arm during application.  You can also adjust the tension of this arm.  To set it properly, push the container pressure arm slightly below the top of your container.  The arm is spring loaded and should allow you to slip the container into position and maintain pressure.

2. Move the label sensor closer to either edge of the label or toward the center if it is already at the edge.

3. Move the container idler roller closer to the container drive roller.  It should be as close as possible while still providing enough support to hold the container.

4. Place the container on the AP362 while the drive roller is moving.  Watch the container for excessive up and down movement.  If the container shape is not a perfect cylinder it will cause the label to bounce.  Remove the container from the AP362.  Press the foot switch.  Be ready to catch the label as it comes off the peel edge.  If it comes completely off, you know the container is causing the problem.  

5. Very light plastic containers can also cause bouncing.  Try filling the container before applying the label.

6. (Advanced Option!)  You may also adjust the label sensor trigger point if it has come out of calibration.  The sensor flag trigger point may be too close to the container drive roller.  If that is the case, the slightest bump/bubble in the label will cause the liner drive roller to stop, therefore stopping the label from applying.  It should be stopping the liner drive roller between .042 and .058 inches from the peel edge.  You can gauge the trigger point by removing labels and containers from the applicator and then depressing the flag so that it is touching the container drive roller.  Press the foot switch.  Now slowly let the flag fall back toward the peel edge.  It should stop the liner drive roller between .042 and .058 inches from the peel edge.  You can make a gauge by measuring the thickness of several sheets of paper or Post It notes.  .058” is approximately 15 Post It notes.  (13 Post It notes was .042”.)  If it is out of position you can BEND the sensor flag into position.  There is a pivot point on the sensor flag that can be bent by hand.
