Chapter 1 Troubleshooting
FIP-1. 45 Paper Jam 075-101
Step Check
Remedy
Yes No
Possible causative parts:
HARNESS ASSY L SIDE (PL3.1.18)
SENSOR PHOTO (PL3.2.13)
PWBA MCU (PL8.2.13)
1
Checking the customer operation
Did the customer insert the paper to the SSF during print?
After print
completion, insert
the paper to the
SSF.
Go to step 2.
2
Checking the SSF No Paper Sensor for operation
Does the number on the screen increase by one, when the
actuator (ACTUATOR SSI) is operated by paper.
Checked by [Digital Input] - [DO-0] in [IOT Diag] of
diagnosis.
Go to step 3. Go to step 4.
3
Checking the error
Does the error still occure when printing?
Replace the
PWBA MCU.
(Refer to Removal
43/Replacement
11)
End of work.
4
Checking the connectors of the SENSOR PHOTO Paper
Sensor) for connection
Check the connections between the PWBA MCU and
SENSOR PHOTO.
Are P/J23 and P/J233 connected correcly?
Go to step 6.
Reconnect the
connector(s) P/
J23 and/or P/J233
correctly, then go
to step 5.
5 Does the error still occur when printing? Go to step 6. End of work.
6
Checking the HARN ASSY L SIDE for continuity
Disconnect J23 from the PWBA MCU.
Disconnect J233 from the SENSOR PHOTO.
Is each cable of J23 <=> J233 continuous?
Go to step 7.
Replace the
HARN ASSY L
SIDE.
7
Checking the power to the SENSOR PHOTO
Disconnect J23 from the PWBA MCU.
Is the voltage across P23-6pin <=> ground on the PWBA
MCU, about +3.3 VDC?
Go to step 8.
Replace the
PWBA MCU.
(Refer to Removal
43/Replacement
11)
8
Checking the SENSOR PHOTO for operation
Check the voltage across J23-8pin <=> ground on the
PWBA MCU.
Remove the CHUTE LOW (PL3.2.27) once to check the
operation.
Does the voltage change, when the ACTUATOR SSI is
operated?
Replace the
PWBA MCU.
(Refer to Removal
43/ Replacement
11.)
Replace the
SENSOR
PHOTO.
