C1030 PF lift motor 1 error (optional paper
feeder)
After cassette 3 is inserted, PF lift switch
1 does not turn on within 12 s. This error
is detected two times successively.
During driving the motor, the lift overcur-
rent protective monitor signal is detected
for 500 ms or more two times succes-
sively. However, the first 1 s after PF lift
motor 1 is turned on is excluded from
detection.
C1040 PF lift motor 2 error (optional paper
feeder)
After cassette 4 is inserted, PF lift switch
2 does not turn on within 12 s. This error
is detected two times successively.
During driving the motor, the lift overcur-
rent protective monitor signal is detected
for 500 ms or more two times succes-
sively. However, the first 1 s after PF lift
motor 2 is turned on is excluded from
detection.
C1100 PF lift motor 1 error (optional 3000-
sheet paper feeder)
A motor over-current signal is detected
continuously for 1 s or longer.
C1110 PF lift motor 2 error (optional 3000-
sheet paper feeder)
A motor over-current signal is detected
continuously for 1 s or longer.
