075-135 MPT Registration Sensor On JAM RAP
BSD-ON:8.1/8.7
After the MPT Feed Solenoid turned On, the Registration Sensor did not turn On within the
specified time.
Initial Actions
• Power OFF/ON
Procedure
Check the guide. The guide is set correctly.
YN
Set the guide correctly.
Check the installation of the MPT. The MPT is installed correctly.
YN
Install the MPT correctly.
Check for foreign substances, distortion and paper powder in the paper transport path. No
distortion, foreign substances, or paper powder are found in the paper transport path.
YN
Clear away the foreign substances and paper powder. Correct the distortion.
Execute Component Control [089-100 Registration Sensor]. Manually activate the actuator of
the Registration Sensor (PL 2.4).
The display changes.
YN
Check the connection of P/J104. P/J104 is connected correctly.
YN
Connect P/J104.
Check the wire between J104 and J403 for an open circuit or a short circuit (BSD 8.7 Flag
1/Flag 2).
The wire between J104 and J403 is conducting without an open circuit or
a short circuit.
YN
Repair the open circuit or short circuit.
Measure the voltage between the MCU PWB P403B-13 (+) and GND (-) (BSD 8.7 Flag
2).
The voltage is approx. +5VDC.
YN
Replace the MCU PWB (PL 9.1).
Measure the voltage between the MCU PWB P403B-8 (+) and GND (-) (BSD 8.7 Flag 1).
Actuate the Registration Sensor with paper. The voltage changes.
YN
Replace the Registration Sensor (PL 2.4).
Replace the MCU PWB (PL 9.1).
Execute Component Control [071-036 Main Motor ON]. The Main Motor in the Main Drive
Assembly starts rotating and the Fuser starts up.
YN
Go to the OF 3 (MAIN DRIVE ASSY RAP).
Execute Component Control [071-012 MPT Feed Solenoid ON]. The MPT Feed Solenoid (PL
7.2) can be heard.
YN
Check the connections of P/J205 and P/J411. P/J205 and P/J411 are connected cor-
rectly.
YN
Connect P/J205 and P/J411.
Measure the resistance of the MPT Feed Solenoid (PL 7.2) (BSD 8.1 Flag 1). (Between
P205-1 and P205-2).
The resistance is approx. 90Ohm.
YN
Replace the MPT Feed Solenoid (PL 7.2).
Check the wire between P205 and J411 for an open circuit or a short circuit (BSD 8.1 Flag
1).
The wire between P205 and J411 is conducting without an open circuit or a
short circuit.
YN
Repair the open circuit or short circuit.
Replace the MCU PWB (PL 9.1).
Replace the MCU PWB (PL 9.1).
