Troubleshooting
MOTOR ASSY DUP MOTOR ASSY DUP INV
HARNESS ASSY MAIN HARNESS-ASSY DUP2
PWBA MCU LV/HVPS
HARNESS-ASSY DUP1 PWBA DUP-L
Step Check Yes No
1
Check of MOTOR ASSY DUP (DUP Lower
Motor) and MOTOR ASSY DUP (DUP
Upper Motor) attachment
Are the Lower and Upper MOTOR ASSY
DUP attached correctly?
Go to Step [2]. Re-attach, and
go to step [2].
2
Check of load of transmission section of
MOTOR driving force
Do the Gears that transmit rotation of
MOTOR rotate smoothly?
Go to Step [3]. Replace parts
that hinder
rotation.
3
Continuity check of HARNESS ASSY MAIN
Disconnect the P/J420 from PWBA MCU.
Is the continuity normal between all terminals
of J420 ↔ J607 (connector on the printer to
connect Duplex)?
Go to Step [4]. Repair broken
or shorted part.
4
Continuity check of HARNESS-ASSY DUP2
Disconnect P/J443 from PWBA DUP-L.
Is the continuity normal between all terminals
of J443 ↔ P607 (connector on Duplex to be
connected to the printer)?
Go to Step [5]. Replace
HARNESS-
ASSY DUP2.
5
24 VDC power supply check to MOTOR
ASSY DUP (DUP Lower Motor)
The voltage of both P442-1 ↔ Frame Chassis
and P442-2 ↔ Frame Chassis on PWBA
DUP-L are 24 VDC?
Go to Step [6]. Go to Step [13].
6
24 VDC power supply check to MOTOR
ASSY DUP INV (DUP Upper Motor)
The voltage of both J612-6 ↔ Frame Chassis
and P612-5 ↔ Frame Chassis on PWBA
DUP-L are 24 VDC?
Go to Step [7]. Go to Step [12].
7
Check after replacement of PWBA DUP-L
Replace PWBA DUP-L. (p.442)
Does the error recur when the power is turned
ON?
Go to Step [8]. End of
procedure
8
Check after replacement of MOTOR ASSY
DUP (DUP Lower Motor)
Replace MOTOR ASSY DUP. (p.443)
Does the error recur when the power is turned
ON?
Go to Step [9]. End of
procedure
9
Check after replacement of MOTOR ASSY
DUP INV (DUP Upper Motor)
Replace MOTOR ASSY DUP. (p.424)
Does the error recur when the power is turned
ON?
Go to Step [10]. End of
procedure
10
Power supply check to PWBA MCU
Is the specified DC voltage being supplied to
the following terminals on PWBA MCU?
P410-1 ↔ P410-2: 3. 3 VDC
P410-3 ↔ P410-4: 5 VDC
P410-5/6 ↔ P410-7/8: 24 VDC
Replace PWBA
MCU. (p.407)
Go to Step [11].
Step Check Yes No
