PWBA MCU LV/HVPS

HARNESS-ASSY DUP1 PWBA DUP-L

Step Check Yes No
1Check 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].
2Check 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.
524 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].
624 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].
7Check 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
8Check 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
9Check 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
