Checking the CLUTCH ASSY PH REGI for operation
Does the CLUTCH ASSY PH REGI operate properly?
Checked by [Digital Output] - [DO-29(Control Panel)/REGI
CLUTCH ON(PC)] in diagnosis.
Go to step 10. Go to step 31.
10
Checking the FUSER
Are there any remaining paper and/or foreign substance in
the FUSER ASSY?
Warning: Start the operation after the FUSER ASSY
has cooled down.
Remove the
paper and/or sub-
stance, then go to
step 11.
Go to step 11.
11
Checking the ROLL REGI RUBBER and ROLL REGI
METAL for shape and operation
Are ROLL REGI RUBBER and ROLL REGI METAL
installed correctly?
Also are they not contaminated and /or damaged, and
rotate smoothly?
Check these ROLLs by turning them with your finger.
Go to step 12.
Replace the
defective
ROLL(s).
12
Checking the TRANSFER ASSY for installation
Reseat the TRANSFER ASSY.
Does the error still occur when printing?
Replace the
PWBA MCU.

End of work
13
Checking the connectors of the Exit Sensor on the FUSER
ASSY for connection
Check the connections between the PWBA MCU and
FUSER ASSY.
Are P/J17 and P/J171 connected surely?
Go to step 14.
Reconnect the
connector(s)
P/J17 and/or
P/J171 surely.
14
Checking the HARN ASSY FUSER for continuity
Disconnect P/J17 from the PWBA MCU.
Disconnect P/J171 from the FUSER.
Is each cable of P/J17 <=> P/J171 continuous?
Go to step 15.
Replace the
HARN ASSY
FUSER.
15
Checking the power to Exit Sensor on the FUSER ASSY
Disconnect the connector of P/J17 on the PWBA MCU.
Is the voltage across ground <=> J17-1pin on the PWBA
MCU, about +3.3 VDC?
Go to step 16.
Replace the
PWBA MCU.
(Refer to Removal
30/Replacement
14.)
16
Checking the Exit Sensor for operation
Measure the voltage across ground <=> P/J17-3pin on the
PWBA MCU.
Does the voltage change, every time the actuator of the
Exit Sensor is operated? Replace the
PWBA MCU.
(Refer to Removal
30/Replacement
14.)
Replace the
FUSER ASSY.
(Refer to Removal
8/Replacement
36.)
17
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 18.
Reconnect the
connector(s)
P/J29, P/J292
and/or P/J2922
surely.
18
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 19.
Replace the
HARN ASSY
REGI SNR.
Step Check Yes No
