Label edges fold over, catch or tear, on the sensor as they are applied to the container. (AP360-AP362-AP380-AP550)
The Teflon-coated sensor flag moves forward/backward to detect gaps between labels. This tells the applicator when to stop applying the label.
1. Clean the Sensor Flag. Over time adhesive from the labels can build up on the sensor flag just above the container rollers. Periodically clean the top of the sensor with a q-tip and alcohol.
2. Move the sensor to the right or left edge of the label. This can reduce the change of tearing.
3. Worn Sensor Flag. If the Teflon coating is worn off the flag it will more easily catch adhesive build-up. You can purchase a new flag here.
4. Adhesive on label sides. If labels are wound too tightly, the adhesive can squeeze out from the bottom and be deposited on the sides of the labels. This is more likely with rubber-based adhesives. Acrylic-based adhesives are recommended for the applicator. Primera labels all have acrylic adhesive. Remove the label from the liner and touch the sides to check for tackiness.
