077-103 Exit Sensor 1 Off Jam (too long) RAP
BSD-ON:10.3
After the Fuser Exit Sensor turned On, the Fuser Exit Sensor did not turn Off within the speci-
fied time.
Initial Actions
Check for torn paper, components out of position, or paper dust in the paper transport path.
Procedure
Check the installation of the Fuser. The Fuser is installed correctly.
Y N
Install the Fuser correctly.
Open Left Upper Cover Assembly and verify that Exit 1 Gate (PL 8.4) is free to move. Exit 1
Gate is free to move.
Y N
Repair as required (PL 8.4).
Execute Component Control [077-105 Fuser Exit Sensor]. Manually activate the actuator of the
Fuser Exit Sensor (PL 7.1). The display changes.
Y N
Check the connections of P/J120 and P/J422. Connections are connected correctly.
Y N
Connect P/J120 and P/J422.
Check the wire between P/J120 and P/J422 for an open circuit or a short circuit (BSD
10.2 Flag 5/Flag 6). The wire are conducting without an open circuit or a short cir-
cuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between the MCU PWB P422-9 (+) and GND (-) (BSD 10.2 Flag 6).
The voltage is approx. +5VDC.
Y N
Replace the MCU PWB (PL 11.1).
Measure the voltage between the MCU PWB P422-11 (+) and GND (-) (BSD 10.2 Flag
5).Actuate the Fuser Exit Sensor with paper. The voltage changes.
Y N
Replace the Fuser Exit Sensor (PL 7.1).
Replace the MCU PWB (PL 11.1).
Execute Component Control [042-001 Main Motor ON]. The Main Motor in the Main Drive
Assembly starts rotating and the Fuser starts up.
Y N
Go to the OF 3 (MAIN DRIVE ASSY RAP).
Check the paper transport drives and repair as required (PL 11.1).
