QLS-4100 Xe 3-7
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.
