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.
Poor contact in the
connector termi-
nals.
Check the connection of connector YC15 on
the engine PWB and the connector on the
PF main PWB, and the continuity across the
connector terminals. Repair or replace if
necessary.
Broken gears or
couplings of PF lift
motor 1.
Replace PF lift motor 1.
Defective PF lift
motor 1.
Check for continuity across the coil. If none,
replace PF lift motor 1.
Defective PF lift
switch 1.
Check if YC1-7 on the PF main PWB goes
low when PF lift switch 1 is turned off. If not,
replace PF lift switch 1.
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.
Poor contact in the
connector termi-
nals.
Check the connection of connector YC15 on
the engine PWB and the connector on the
PF main PWB, and the continuity across the
connector terminals. Repair or replace if
necessary.
Broken gears or
couplings of PF lift
motor 2.
Replace PF lift motor 2.
Defective PF lift
motor 2.
Check for continuity across the coil. If none,
replace PF lift motor 2.
Defective PF lift
switch 2.
Check if YC1-9 on the PF main PWB goes
low when PF lift switch 2 is turned off. If not,
replace PF lift switch 2.
C1100 PF lift motor 1 error (optional 3000-
sheet paper feeder)
A motor over-current signal is detected
continuously for 1 s or longer.
Poor contact in the
connector termi-
nals.
Check the connection of connector YC15 on
the engine PWB and the connector on the
PF main PWB, and the continuity across the
connector terminals. Repair or replace if
necessary.
PF lift motor 1 does
not rotate correctly
(the motor is over-
loaded).
Check the gears and remedy if necessary.
C1110 PF lift motor 2 error (optional 3000-
sheet paper feeder)
A motor over-current signal is detected
continuously for 1 s or longer.
Poor contact in the
connector termi-
nals.
Check the connection of connector YC15 on
the engine PWB and the connector on the
PF main PWB, and the continuity across the
connector terminals. Repair or replace if
necessary.
PF lift motor 2 does
not rotate correctly
(the motor is over-
loaded).
Check the gears and remedy if necessary.
