Checking the ROLL ASSY TURN and ROLL ASSY FEEDs
for shape and operation
Remove the paper cassette.
Are ROLL ASSY TURN and ROLL ASSY FEEDs installed
correctly?
Also are they not contaminated and /or damaged, and
rotate smoothly?
Check these items by turning them with your finger.
Go to step 10.
Replace the
defective
ROLL(s).
10
Checking after replacing the 550 OPTION FEEDER
Replace the 550 OPTION FEEDER. (Refer to Removal 44/
Replacement 46)
Does the error still occur when printing?
Replace the
PWBA MCU.
(Refer to Removal

End of work
11
Checking the connectors of the SENSOR PHOTO (REGI
SENSOR) for connection
Check the connections between the PWBA MCU and
REGI SENSOR.
Are P/J29, P/J292 and P/J2922 connected surely?
Go to step 12.
Reconnect the
connector(s)
P/J29, P/J292
and/or P/J2922
surely.
12
Checking the HARN ASSY REGI SNR for continuity Dis-
connect P/J2922 from the REGI SENSOR.
Disconnect P/J292 from the HARN ASSY R SIDE.
Is each cable of P/J2922 <=> P/J292 continuous?
Go to step 13.
Replace the
HARN ASSY
REGI SNR.
13
Checking the HARN ASSY R SIDE for continuity
Disconnect P/J29 from the PWBA MCU.
Disconnect P/J292 from the HARN ASSY REGI SNR.
Is each cable of P/J29 <=> P/J292 continuous?
Go to step 14.
Replace the
HARN ASSY R
SIDE.
14
Checking the power to REGI SENSOR
Disconnect the connector of P/J29 on the PWBA MCU.
Is the voltage across ground <=> J29-8pin on the PWBA
MCU, about +3.3 VDC?
Go to step 15.
Replace the
PWBA MCU.
(Refer to Removal
30/ Replacement
14.)
15
Checking the REGI SENSOR for operation
Measure the voltage across ground <=> J29-10pin on the
PWBA MCU.
Does the voltage change, every time the actuator of the
REGI SENSOR is operated? Replace the
PWBA MCU.
(Refer to Removal
30/ Replacement
14.)
Replace the SEN-
SOR PHOTO
(REGI SENSOR).
16
Checking the connectors of the DRIVE ASSY OPT FDR for
connection
Check the connections between the PWBA OPT FDR and
DRIVE ASSY OPT FDR.
Are P/J422 and P/J4222 connected surely?
Go to step 17.
Reconnect the
connector(s)
P/J422 and/or P/
J4222 surely.
17
Checking the HARNESS ASSY C2 MOT for continuity
Disconnect P/J422 from the PWBA OPT FDR.
Disconnect P/J4222 from the DRIVE ASSY OPT FDR.
Is each cable of P/J422 <=> P/J4222 continuous?
Go to step 18.
Replace the
HARN ASSY
C2 MOT.
Step Check Yes No
