Step Check Yes No
1
Check of DRIVE ASSY FEED attachment
Is DRIVE ASSY FEED attached correctly?
Go to Step [2]. Re-attach, and
go to step [2].
2
Continuity check of HARNESS-ASSY
FEED MAIN
Disconnect P/J437 from PWBA TRAY
CONT.
Do all of the wiring below have normal
continuity?
J437-1 ↔ J440-5
J437-2 ↔ J440-4
J437-4 ↔ J440-2
J437-5 ↔ J440-1
Go to Step [3]. Replace
HARNESS-
ASSY FEED
MAIN.
3
24 VDC power supply check to DRIVE
ASSY FEED
The voltage of P440-2 ↔ P440-1 on PWBA
FEED DRV is 24 VDC?
Go to Step [4]. Go to Step [5].
4
Check of FEED MOTOR START signal
The voltage of P440-5 ↔ P440-1 on PWBA
FEED DRV is xx VDC when FEED MOTOR
START signal is ON?
Replace DRIVE
ASSY FEED.
(p.458)
Go to Step [10].
5
24 VDC power supply check to PWBA
TRAY 500
The voltage of P435-9/10 ↔ P435-7/8 on
PWBA TRAY 500 is 24 VDC?
Replace PWBA
TRAY 500.
(p.456)
Go to Step [6].
6
Continuity check of HARNESS-ASSY FEED 1
Disconnect P/J435 from PWBA TRAY
CONT.
Do all of the wiring below have normal
continuity?
J435-10 ↔ P608-1 (connector on Feeder to
be connected to the printer)
J435-9 ↔ P608-2
J435-8 ↔ P608-3
J435-7 ↔ P608-4
Go to Step [7]. Replace PWBA
TRAY 500.
(p.456)
7
Continuity check of HARNESS ASSY MAIN
Disconnect P/J421 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J421-1 ↔ J608-10 (connector on the printer
to connect Feeder)
J421-2 ↔ J608-9
J421-3 ↔ J608-8
J421-4 ↔ J608-7
Go to Step [8]. Repair broken
or shorted part.
8
24 VDC power supply check to PWBA MCU
The voltage of P410-5/6 ↔ P410-7/8 on
PWBA MCU is 24 VDC?
Replace PWBA
MCU. (p.404)
Go to Step [9].
9
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?
J410-5 ↔ J502-5
J410-6 ↔ J502-6
J410-7 ↔ J502-7
J410-8 ↔ J502-8
Replace LV/
HVPS. (p.407)
Repair broken
or shorted part.
Step Check Yes No
