Step Check Yes No
1
Paper check at SENSOR LOW PASS section
Open Duplex.
Is there any paper remaining at the SENSOR
LOW PASS section?
Remove the
remaining paper
and proceed to
Step [2].
Go to Step [2].
2Check of ROLLER ASSY DUP, ROLLER
ASSY DUP OUT and ROLL PINCH DUP
Open Duplex.
Are ROLLER ASSY DUP, ROLLER ASSY
DUP OUT, and ROLL PINCH DUP attached
correctly?
Also, do these parts rotate smoothly without
any dirt or damage?
Turn by hand to check.
Go to Step [4]. Replace or re-
attach ROLL in
question, and go
to [3].
3Does the error recur when a test print is
made in the duplex mode? Go to Step [4]. End of
procedure
4Check of transmission of drive force to
ROLLER ASSY DUP
Open Duplex.
Remove COVER-L DUP. (p.414)
Are all gears that transmit rotation of MOTOR
ASSY DUP (Lower Roll Motor) to ROLLER
ASSY DUP turning smoothly?
Turn gears by hand to check.
Go to Step [5]. Replace the
gear in question.
5Operation check of ACTUATOR DUP
Does ACTUATOR DUP move smoothly
without any damage? Does ACTUATOR
DUP leave the sensing area of the sensor when
there is paper? Does it enter the sensing area
when there is no paper?
Go to Step [6]. Replace
ACTUATOR
DUP. (p.431)
6Operation check of SENSOR LOW PASS
The voltage of P443-15 ↔ P443-14 on
PWBA DUP-L is 0 VDC when ACTUATOR
enters the sensing area of SENSOR LOW
PASS, and is 5 VDC when it leaves the
sensing area?
Go to Step [7]. Go to Step [11].
7
Continuity check of HARNESS-ASSY DUP2
Disconnect P/J443 from PWBA DUP-L.
Is the continuity normal between all terminals
of J443 ↔ P607?
Go to Step [8]. Replace
HARNESS-
ASSY DUP2.
8
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 [9]. Repair broken
or shorted part.
9Check after replacement of PWBA DUP-L
Replace PWBA DUP-L. (p.442)
Does the error recur when a test print is made
in the duplex mode?
Replace PWBA
MCU. (p.404) End of
procedure
Step Check Yes No
