Step Check Yes No
1
Shape check of CHUTE FDR ASSY 500
Is the actuator of CHUTE FDR ASSY 500 that
presses SWITCH FEEDER DOOR damaged?
Replace
CHUTE FDR
ASSY 500.
(p.454)
Go to Step [2].
2
Operation check of SWITCH FEEDER DOOR
Disconnect P/J437 from PWBA TRAY 500.
Is there continuity on J437-8 ↔ J437-9 when
SWITCH FEEDER DOOR is pressed, and
does the continuity stop when the switch is
released?
Go to Step [4]. Go to Step [3].
3
Continuity check of HARNESS-ASSY
FEED MAIN
Disconnect P/J437 from PWBA TRAY 500.
Do all of the wiring below have normal
continuity?
J437-8 ↔ J121-2
J437-9 ↔ J121-1
Replace
SWITCH
FEEDER
DOOR. (p.464)
Replace
HARNESS-
ASSY FEED
MAIN.
Actuator
4
Continuity check of HARNESS-ASSY FEED 1
Disconnect P/J435 from PWBA TRAY CONT.
Is the continuity normal between all terminals
of J435 ↔ P608 (connector on Feeder to be
connected to the printer)?
Go to Step [5]. Replace
HARNESS-
ASSY FEED 1.
(p.462)
5
Continuity check of HARNESS ASSY MAIN
Disconnect P/J421 from PWBA MCU.
Is the continuity normal between all terminals
of J421 ↔ J608 (connector on the printer to
connect Feeder)?
Go to Step [6]. Repair broken
or shorted part.
6
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.404)
Go to Step [7].
7
Continuity check of HARNESS ASSY MAIN
Disconnect P/J410 from PWBA MCU and P/
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
or shorted part.
