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.
