FIP-1.36 075-101 / 075-102 / 075-923: IOT SSI Insert JAM / IOT SSI Paper Pullout JAM /
Waiting for reseat paper of SSI
Step
Possible causative parts:
HARN ASSY L SIDE (PL3.1.18)
SENSOR PHOTO (PL3.2.13)
PWBA MCU (PL8.2.13)
Checking the customer operation.
1
Did the customer insert the paper to the SSI during print?
Checking the SSI No Paper Sensor for operation.
Does the number on the screen increase by one, when the
2 actuator (ACTUATOR SSI) is operated by paper.
Checked by [Digital Input] - [Main Motor] in [IOT Diag] of
diagnosis.
Checking the error.
3
Does the error still occur when printing?
Checking the connectors of the SENSOR PHOTO (SSI No
Paper Sensor) for connection.
Check the connections between the PWBA MCU and
SENSOR PHOTO.
Are P/J23 and P/J233 connected correctly?
4
5 Does the error still occur when printing?
Checking the HARN ASSY L SIDE for continuity.
Disconnect J23 from the PWBA MCU.
6
Disconnect J233 from the SENSOR PHOTO.
Is each cable of J23 <=> J233 continuous?
Checking the power to the SENSOR PHOTO.
Disconnect J23 from the PWBA MCU.
7
Is the voltage across P23-6pin <=> ground on the PWBA
MCU, about +3.3 VDC?
Checking the SENSOR PHOTO for operation.
Check the voltage across J23-8pin <=> ground on the
PWBA MCU.
8 Remove the CHUTE ASSY LOW (PL3.2.27) once to check
the operation.
Does the voltage change, when the ACTUATOR SSI is
operated?
