TROUBLESHOOTING FIP according to the printer message 185
9Check 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 [11] . Replace or re-
attach ROLL in
question, and go
to [10].
10 Does the error recur when a test print is
made in the duplex mode? Go to Step [11] . End of
procedure
11 Check 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 [12] . Replace the
gear in question.
12 Check after replacement of MOTOR ASSY
DUP (Lower Roll Motor)
Replace MOTOR ASSY DUP. (p.443)
Does the error recur when a test print is made
in the duplex mode?
Go to Step [13] . End of
procedure
13 Check 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?
Go to Step [14] . End of
procedure
14 Shape and operation check of ROLL
ASSY-PRE REGI and ROLL-PINCH
Open CHUTE ASSY-REAR.
Are ROLL ASSY-PRE REGI and ROLL-
PINCH attached correctly?
Also, do these parts rotate smoothly without
any dirt or damage?
Turn by hand to check.
Go to Step [15] . Replace ROLL
in question.
Step Check Yes No
15 Does the error recur when a test print is
made? Go to Step [16]. End of
procedure
16 Check of paper position
Is the leading edge of the paper passing
through PRE REGI ROLL?
Go to Step [17]. Go to Step [29].
17 Operation check of ACTUATOR-REGI
Does ACTUATOR-REGI move smoothly
without any damage? Does it enter the sensor
sensing area when there is paper? Does it
leave the sensor sensing area when there is no
paper?
Go to Step [18]. Replace
ACTUATOR-
REGI. (p.335)
18 Operation check of SENSOR REGI
The voltage of P408-12 ↔ P408-11 on
PWBA MCU is 0 VDC when ACTUATOR
REGI enters the sensor sensing area, and is 5
VDC when it leaves the sensing area?
Go to Step [24]. Go to Step [19].
19
5 VDC power supply check to SENSOR REGI
The voltage of P408-10 ↔ P408-11 on
PWBA MCU is 5 VDC?
Go to Step [20]. Go to Step [22].
20 Continuity check of HARNESS-ASSY P/H1
Disconnect the P/J408 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J408-10 ↔ J603-3
J408-11 ↔ J603-2
J408-12 ↔ J603-1
Go to Step [21]. Replace
HARNESS-
ASSY P/H1.
21 Continuity check of HARNESS-ASSY P/H2
Disconnect P/J603 and P/J102 from PWBA
MCU.
Do all of the wiring below have normal
continuity?
P603-10 ↔ J102-3
P603-11 ↔ J102-2
P603-12 ↔ J102-1
Replace
SENSOR
REGI. (p.336)
Replace
HARNESS-
ASSY P/H2.
Step Check Yes No
