Labels are skipping, applying inconsistently or -SC- is displayed. (AP550).

Center the label Stock. The label stock must be centered in the feed space so that the gaps between labels intersect with the tick mark in the metal. The tick mark indicates the sensor position.

Black Mark(Reflective) or Die Cut Mode. Make sure you are in the correct Mode for your installed label stock. Clear labels must have a black mark on the back to be seen by the sensor. See Section 3.2.

Preprinted Labels. Labels with printing on the back of the liner may not work correctly since the sensor may mistakenly detect the printing on the back (or the front) of the label stock as a gap between labels.  You may be able to adjust the position of the labels left or right in the feed area so the sensor avoids the printing. 

A sensor calibration may be necessary. 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 or you may watch this AP550 Calibration Video.

1. Load the label stock as described in Section 2 of the manual.    The label stock must be centered in the feed space so that the gaps between labels intersect with the tick mark in the metal.   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.
