Step Check Yes No
1Shape 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].
3Continuity 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

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)?
