Step Check Yes No
1Shape check of COVER UP-DUP TRANS
Is the actuator of COVER UP-DUP TRANS
that presses SWITCH-DUP DOOR damaged?
Replace
COVER UP-
DUP TRANS.
(p.437)
Go to Step [2].
2Operation check of SWITCH-DUP DOOR
Disconnect P/J444 from PWBA DUP-L.
Is there continuity on J444-1 ↔ J444-2 when
SWITCH-DUP DOOR is pressed, and does
continuity stop when the switch is released?
Go to Step [4]. Go to Step [3].
3
Continuity check of HARNESS-ASSY DUP1
Disconnect P/J444 from PWBA DUP-L.
Do all of the wiring below have normal
continuity?
J444-1 ↔ J122-2
J444-2 ↔ J122-1
Replace
SWITCH-DUP
DOOR. (p.430)
Replace
HARNESS-
ASSY DUP1.

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
Continuity check of HARNESS ASSY MAIN
Disconnect the P/J420 from PWBA MCU.
Is the continuity normal between all terminals
of J420 ↔ J607?
Go to Step [6]. Repair broken
or shorted part.
6Check after replacement of PWBA DUP-L

Does the error recur when the power is turned
ON?
Go to Step [8]. End of
procedure
8
Continuity check of HARNESS ASSY MAIN

J502 from LV/HVPS.
Do all of the wiring below have normal
continuity?
J410-1 ↔ J502-1
J410-2 ↔ J502-2
J410-3 ↔ J502-3
J410-4 ↔ J502-4
J410-5 ↔ J502-5
J410-6 ↔ J502-6
J410-7 ↔ J502-7
J410-8 ↔ J502-8
Replace LV/
HVPS. (p.407) Repair broken
