FIP-1. 67 Insert Output 075-920 / 075-921
Step
Possible causative parts:
No Paper Sensor (PL3.2.13)
HARN ASSY L SIDE (PL10.4.18)
PWBA MCU(PL10.7.7)
Checking the operation
1
Did you insert the paper into the SSF at side 2 printing?
Checking the operation
2 Did you pull the paper out from the SSF when side 2
printing?
Checking the operation
3
Did you insert the correct paper into the SSF?
Checking the SSF No Paper Sensor (SENSOR PHOTO) for
operation
Remove the CHUTE LOW (PL3.2.27) once to check the
operation.
4 Does the number on the screen increase by one, when the
actuator (ACTUATOR SSI) of the SSF No Paper Sensor
(SENSOR PHOTO) is operated?
Checked by [Digital Input]-[DI-0] of the [IOT Diag] on the
[Printer] of the diagnosis.
Checking the connectors of the SENSOR PHOTO (SSF No
Paper Sensor) for connection
5 Check the connections between the PWBA MCU and
SENSOR PHOTO.
Are P/J23 and P/J233 connected correctly?
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 LOW (PL3.2.27) once to check the
operation.
Does the voltage change, when the ACTUATOR SSI is
operated?
