C1030 Lift motor 3 error
• When cassette 3 is inserted, lift limit
switch 3 does not turn on within 33 s of
lift motor 3 turning on. This error is
detected four times successively.
• During copying, lift limit switch 3 does
not turn on within 1 s of lift motor 3
turning on. This error is detected four
times successively.
Broken gears or
couplings of lift
motor 3.
Replace lift motor 3.
Defective lift motor
3.
Check for continuity across the coil. If none,
replace lift motor 3.
Poor contact of lift
motor 3 connector
terminals.
Reinsert the connector. Also check for conti-
nuity within the connector cable. If none,
repair or replace the cable.
Defective lift limit
switch 3.
Run maintenance item U031 and turn lift
limit switch 3 on and off manually. Replace
lift limit switch 3 if indication of the corre-
sponding sensor on the touch panel is not
displayed in reverse.
Poor contact of lift
limit switch 3 con-
nector terminals.
Reinsert the connector. Also check for conti-
nuity within the connector cable. If none,
repair or replace the cable.
Defective casette
PWB.
Replace the casette PWB
C1040 Lift motor 4 error
• When cassette 4 is inserted, lift limit
switch 4 does not turn on within 33 s of
lift motor 4 turning on. This error is
detected four times successively.
• During copying, lift limit switch 4 does
not turn on within 1 s of lift motor 4
turning on. This error is detected four
times successively.
Broken gears or
couplings of lift
motor 4.
Replace lift motor 4.
Defective lift motor
4.
Check for continuity across the coil. If none,
replace lift motor 4.
Poor contact of lift
motor 4 connector
terminals.

nuity within the connector cable. If none,
repair or replace the cable.
Defective lift limit
switch 4.

limit switch 4 on and off manually. Replace
lift limit switch 4 if indication of the corre-
sponding sensor on the touch panel is not
displayed in reverse.
Poor contact of lift
limit switch 4 con-
nector terminals.

C1140 Side feeder lift motor going up error
(optional side feeder)
• Upper limit detection switch does not
turn off within 15 s of the side feeder
lift motor starting (within 200 ms during
paper feeding). This error is detected
four times successively.
Poor contact of
upper limit detec-
tion switch connec-
tor terminals.
Reinsert the connector. Also check for conti-
nuity within the connector cable. If none,
repair or replace the cable.
Defective side
feeder main PWB.
Replace the side feeder main PWB.
Defective side
feeder lift motor.
Run maintenance mode U247 and measure
the voltage between terminals YC5-A12
(side feeder main circuit board) and YC6-
B11. (Make sure all of LUSSW, UCSSW,
LLSSW and RCSSW are off.)
Despite either DC24V or DC-24V is
observed but if the side feeder lift motor
does not operate, replace the side feeder lift
motor.
