FIP-1.69 072-900: IOT Remain Option Feeder JAM
Step Check
Remedy
Yes No
Possible causative parts:
SENSOR PHOTO (PL12.4.13)
PWBA MCU (PL8.3.6)
HARNESS ASSY TRAY COMP (PL12.2.20)
1
Checking the Paper Path Sensor (SENSOR PHOTO) for
operation.
Does the number on the screen increase by one, when the
actuator (ACTUATOR REGI IN) is operated?
Checked by [Digital Input] - [OptionPathSensor] in [IOT
Diag] of diagnosis.
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
Go to step 2.
2
Checking the connectors for connection.
Check the connections between the PWB ASSY FEED MG
AIO and Paper Path Sensor.
Are P/J420 and P/J4200 connected correctly?
Go to step 3.
Reconnect the
connector(s) P/
J420 and/or P/
J4200 correctly.
3
Checking the HARNESS ASSY TRAY COMP for continuity.
Disconnect J420 from the PWB ASSY FEED MG AIO.
Disconnect J4200 from the Paper Path Sensor.
Is each cable of J420 <=> J4200 continuous?
Go to step 4.
Replace the
HARNESS ASSY
TRAY COMP.
4
Checking the power to the SENSOR PHOTO.
Disconnect J420 from the PWB ASSY FEED MG AIO.
Is the voltage across P420-6pin <=> ground on the PWB
ASSY FEED MG AIO, about +3.3 VDC?
Replace the KIT
FEEDER ASSY
OPT MG AIO.
(Refer to
REP11.1.)
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
