PM23c, PM43, and PM43c Mid-Range Printer User Manual
The label gap sensor is a transmissive sensor that controls how the
printer feeds media by detecting gaps between the labels. The black
mark sensor is a reflective sensor that detects black marks on
continuous media.
The sensor contains a blue LED which is strong enough to see through
media. You can use the blue LED to help determine the proper location
for the sensor.
