FIP1.41 Paper Jam 077-903

Step
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)
Checking the jam
1 Remove the jammed paper.
Does the error still occur when printing?
Checking the SENSOR PHOTO (REGI SENSOR) for oper-
ation
Does the number on the screen increase by one, every
2 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.
Checking the paper feed
3
Does the multiple paper feed occur?
Checking the connectors of the SENSOR PHOTO (REGI
SENSOR) for connection
4 Check the connections between the PWBA MCU and
REGI SENSOR.
Are P/J29, P/J292 and P/J2922 connected surely?
Checking the HARNESS ASSY REGI SNR for continuity
Disconnect P/J2922 from the REGI SENSOR.
5
Disconnect P/J292 from the HARN ASSY R SIDE.
Is each cable of P/J2922 <=> P/J292 continuous?
Checking the HARN ASSY R SIDE for continuity
Disconnect P/J29 from the PWBA MCU.
6
Disconnect P/J292 from the HARN ASSY REGI SNR.
Is each cable of P/J29 <=> P/J292 continuous?
Checking the power to REGI SENSOR
Disconnect the connector of P/J29 on the PWBA MCU.
7
Is the voltage across ground <=> J29-8pin on the PWBA
MCU, about +3.3 VDC?
Checking the REGI SENSOR for operation
Measure the voltage across ground <=> J29-10pin on the
8 PWBA MCU.
Does the voltage change, every time the actuator of the
REGI SENSOR is operated?
