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.
255
× (Threshold level voltage [V])
Adjustment value =
5.0

00
After the mirror starts feeding, it does not complete feeding in the specified time.
After the mirror base starts initializing, or during copying, it does not complete
00
returning in the specified time.
01
Drum motor lock (in the process system)
02
Main motor lock (in the transport system)
Between the master and the mirror controller, the lens/No. 4/5 mirror does not
00
complete the operation in the specified time.
00
Thermistor open detected.
00
Abnormally high temperature is detected in the heat roller.
After the power relay is turned on, the temperature does not reach the specified
00
level in the specified time. Abnormally low temperature detected.
Communication trouble between the master and the operation panel. (Master

41
allowable steps.
When the No. 4/5 mirror motor home position is corrected, there is a shift
42
exceeding the allowable steps.
