RADF empty
sensor adjustment

Used to adjust the threshold value of the RADF empty sensor
sensing level.
When this simulation is executed, the RADF adjusts the
threshold value of the sensor sensing level automatically. After
completion of the adjustment, the adjustment value is dis-
played on the copy quantity display.
The relationship between the adjustment value and the
threshold value is expressed in the following formula.
