077-130 Duplex Out Sensor On Jam RAP
BSD-ON:8.7/9.3/10.5
In the case where there is non-stop Duplex feed, the Registration Sensor did not turn On within
the specified time after the Duplex Sensor turned On.
Initial Actions
Check for torn paper, components out of position, or paper dust in the paper transport path.
Procedure
Check the installation of the DUP Module. The DUP Module is installed correctly.
Y N
Install the DUP Module correctly.
Check the Transport Roll for wear and paper dust. The Transport Roll is ok.
Y N
Replace the Transport Roll (PL 15.5).
Execute Component Control [089-100 Registration Sensor]. Manually activate the actuator of
the Registration Sensor (PL 2.4). The display changes.
Y N
Check the connection of P/J605. P/J605 is connected correctly.
Y N
Connect P/J605.
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.
Y N
Repair the open circuit or short circuit.
Measure the voltage between the MCU PWB P403-B13 (+) and GND (-) (BSD 8.7 Flag
2). The voltage is approx. +5VDC.
Y N
Replace the MCU PWB (PL 11.1).
Measure the voltage between the MCU PWB P403-B8 (+) and GND (-) (BSD 8.7 Flag 1).
Actuate the Registration Sensor with paper. The voltage changes.
Y N
Replace the Registration Sensor (PL 2.5).
Replace the MCU PWB (PL 11.1).
Execute Component Control [071-105 Duplex Sensor]. Actuate the Duplex Sensor (PL 10.1)
with paper. The display changes.
Y N
Check the wire between J123 and J541 for an open circuit or a short circuit (BSD 10.5
Flag 1/Flag 2). The wire between J123 and J541 is conducting without an open cir-
cuit or a short circuit.

Y N
Repair the open circuit or short circuit.
Replace the Duplex Sensor (PL 10.1) If the problem persists, replace the Duplex PWB
(PL 10.1).
Execute Component Control [077-006 Duplex Motor ON]. The Duplex Motor energized.
Y N
Check the wire between J212 and J542 for an open circuit or a short circuit (BSD 10.5
Flag 3). The wire between J212 and J542 is conducting without an open circuit or a
short circuit.
Y N
Repair the open circuit or short circuit.
Replace the Duplex Motor (PL 10.1) If the problem persists, replace the Duplex PWB (PL
10.1).
Replace the Duplex PWB (PL 10.1).
