NOTE:
Ribbon is not displayed in this illustration. The upper and lower sensors are designed to
function with or without ribbon installed.
The upper sensor and lower sensor are used together to detect notches or holes in media with a black or
dark underside. This combination can be found on tag stock that has a black vertical line along one edge on
the underside of the label, interrupted by a notch or hole used as the label length indicator.
1. Position the lower sensor directly under the center of the notch or hole, and then place the upper
sensor directly over the lower sensor.
2. Check the position of the lower sensor by looking through the long, narrow opening in the media guard.
Use the visible red light emitting from the lower sensor as a reference pointer.
3. Use the sensor handle to manually position the sensor to the center of the notch or hole in the media.
Then use the handle on the upper sensor to position it directly above the lower sensor.
NOTE:
When using ribbon, you may need to slide the ribbon to one side to adjust the upper sensor.
4. Select "Advanced Notch" in the Sensors > Control > Gap/Mark Sensor menu. See Sensing Different
Media Types page 40.
5. Perform an Auto Calibrate. See Running Auto Calibrate page 41.
