(4) Front Fixed Sensor
The principle of the front fixed sensor is the same as that of the adjustable sensor.
To use the front fixed sensor, you need to change the Sensor Select menu from “Rear Adj
sensor” to “Front Fixed Sen”.
- DO NOT adjust VR1 and VR2 on the Main PCB. (Leave them at the factory
setting condition.) If it is turned, media sensor sensitivity is changed and the
media detection will not be correctly made.
