Demand Sensor
The print medium demand sensor detects when the level of the print medium in
the transfer head is low. For an accurate reading, the bottom of the sensor must
be positioned no more than 5mm (+/- 1mm) above the transfer head’s top plate.
To adjust the height of the print medium demand sensor, carry out the following:
1. Loosen the screw on the print medium demand sensor, using a jeweller’s
flat bladed screwdriver.
2. Adjust the bottom edge of the demand sensor so that it sits 5mm (+/- 1mm)
above the level of the transfer head’s top plate.
3. Tighten the screw on the print medium demand sensor.
