Step
Checking the HARNESS ASSY OPTION MG AIO for
continuity Disconnect J27 from PWBA MCU.
9
Disconnect P272 from HARNESS ASSY OPTION MG AIO.
Is each cable of J27 <=> P272 continuous?
Checking the connectors of the SENSOR PHOTO (REGI
SENSOR) for connection.
10 Check the connections between the PWBA MCU and
SENSOR PHOTO.
Are P/J23 and P/J232 connected correctly?
Checking the HARNESS ASSY L SIDE MG AIO for
continuity.
11 Disconnect J23 from the PWBA MCU.
Disconnect J232 from the SENSOR PHOTO.
Is each cable of J23 <=> J232 continuous?
Checking the power to the SENSOR PHOTO.
Disconnect J23 from the PWBA MCU.
12
Is the voltage across P23-3pin <=> ground on the PWBA
MCU, about +3.3 VDC?
Checking the SENSOR PHOTO for operation.
Check the voltage across 23-5pin <=> ground on the PWBA
MCU.
13 Remove the CHUTE ASSY LOW (PL3.2.27) once to check
the operation.
Does the voltage change, when the actuator of the
SENSOR PHOTO is operated?
Checking after replacing FEEDER ASSY DUP AIO STD.
14 Replace FEEDER ASSY DUP AIO STD.
Does the error still occur when printing?
Checking after replacing FUSING UNIT.
Replace FUSING UNIT.
Warning: Start the operation after the FUSING UNIT has
15 cooled down.
Does the error still occur when printing?
NOTE: After replacement, be sure to clear life counter
value.
