Chapter 1 Troubleshooting
Version 1 2008.02.15
FIP1.41 Paper Jam 077-903
Step
Check Yes No
Possible causative parts:
HARN ASSY REGI SNR (PL3.2.37)
HARN ASSY R SIDE (PL10.1.15)
SENSOR PHOTO (REGI SENSOR) (PL3.2.30)
PWBA MCU (PL9.1.20)
1
Checking the jam
Remove the jammed paper.
Does the error still occur when printing?
Go to step 2. End of work
2
Checking the SENSOR PHOTO (REGI SENSOR) for oper-
ation
Does the number on the screen increase by one, every
time the actuator of the SENSOR PHOTO (REGI SEN-
SOR) is operated?
Checked by [Digital Input] - [DI-3(Control Panel)/REGI
SNR(PC)] in diagnosis.
Go to step 3. Go to step 4.
3
Checking the paper feed
Does the multiple paper feed occur?
Go to Multiple
Feed in Other FIP.
Replace the
PWBA MCU.
(Refer to Removal
30/Replacement
14)
4
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 5.
Reconnect the
connector(s)
P/J29, P/J292
and/or P/J2922
surely.
5
Checking the HARNESS ASSY REGI SNR for continuity
Disconnect 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 6.
Replace the
HARN ASSY
REGI SNR.
6
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 7.
Replace the
HARN ASSY R
SIDE.
7
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 8.
Replace the
PWBA MCU.
(Refer to Removal
30/Replacement
14.)
8
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).
