Adjusting the Media Sensor
The QLS-4100 Xe is equipped with two intelligent media sensors. One sensor 
is used for gap, or notched media types, and the other is used for reflective 
media types. Under normal operation, the sensor has to be calibrated to the 
media type being used only once. When changing from gap to reflective 
media types or vice-versa, a re-calibration is required. 
The Gap/Notch Sensor is positioned above the media on a movable shaft 
which can be adjusted out up to 2.5“ (64 mm) from the inside edge of the 
media. The Reflective Sensor is positioned below the media in a position fixed 
at 6 mm from the inside edge of the media. 
Before calibrating the printer for gap or notched media, you must adjust the 
position of the sensor so that it clearly “sees” the gap or notch. The 
illustration below shows how to adjust the sensor. 
To adjust the media sensor:
1
Turn the knob clockwise to move the sensor toward the outside edge.
2
Turn the knob counterclockwise to move the sensor toward the inside 
edge.
