FIP-1.70 075-101 / 075-102 / 075-923: IOT SSF Insert JAM / IOT SSF Paper Pullout JAM /
Waiting for reseat paper of SSF
Step Check
Remedy
Yes No
Possible causative parts:
HARNESS ASSY L SIDE MG AIO(PL3.1.18)
SENSOR PHOTO (PL3.2.13)
PWBA MCU (PL8.3.6)
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 SSF) is operated by paper.
Checked by [Digital Input] - [Main Motor] in [IOT Diag] of
diagnosis.
Go to step 3. Go to step 4.
3
Checking the error.
Does the error still occur when printing?
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
End of work.
4
Checking the connectors of the SENSOR PHOTO (SSF No
Paper Sensor) for connection.
Check the connections between the PWBA MCU and
SENSOR PHOTO.
Are P/J23 and P/J233 connected correctly?
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 HARNESS ASSY L SIDE MG AIO 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
HARNESS ASSY
L SIDE MG AIO.
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 KIT
PWBA MCU.
(Refer to
REP8.10.)
8
Checking the SENSOR PHOTO for operation.
Check the voltage across J23-8pin <=> ground on the
PWBA MCU.
Remove the CHUTE ASSY LOW (PL3.2.27) once to check
the operation.
Does the voltage change, when the ACTUATOR SSF is
operated?
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
Replace the
SENSOR
PHOTO.
