Adjusting the Label Gap Sensor

The PF8 printers are fitted with a label gap sensor that detects the slots between tickets and tags or gaps between labels as media if fed past the sensor during printing. The label gap sensor determines the length or tag or labels and controls the media/ ribbon feed accordingly.

The label gap sensor is a center-aligned photoelectric sensor that measures the light that passes through the media path. The transparency of the liner of a label supply may change from batch to batch, making it difficult for the sensor to determine the length of the media. If this happens, the status LED will change from green to orange, indicating you need to adjust the sensor using the Auto-Sensing mode. For more information see

“Understanding Auto-Sensing Mode” on page 17.
