072-105 Tray 2 Registration Sensor On Jam RAP
BSD-ON:8.7/8.2
The Registration Sensor did not actuate in time after the Tray 2 Feed Out Sensor actuated.
Initial Actions
Check that the paper path is free of foreign material and paper dust.
Procedure
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 2.5). The display changes.
Y N
Check the wires between P/J106 and P/J405 for an open circuit or a short circuit (BSD
8.7 Flag 1/Flag 2). The circuit between P/J106 and P/J405 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 P/J405-8A (+) and P/J405-6A (-) (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 P/J405-A7 (+) 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 [077-001 Takeaway Roll Clutch ON]. The Takeaway Roll Clutch
(PL 2.4) energizes.
Y N
Check the connections of P/J218 and P/J424. Connections are connected correctly.
Y N
Connect P/J218 and P/J424.
Measure the resistance of the Takeaway Roll Clutch (PL 2.4 BSD 8.2 Flag 3). (Between
P/J218-1 and P/J218-2) The resistance is approx. 250~100Ohm.
Y N
Replace the Takeaway Roll Clutch (PL 2.4).
Check the wires between P/J218 and P/J424 for an open circuit or a short circuit (BSD
8.2 Flag 4). The circuit between P/J218 and P/J424 is conducting without an open
circuit or a short circuit.

Y N
Repair the open circuit or short circuit.
Replace the MCU PWB (PL 11.1).
Enter Component Control [077-022 Takeaway Motor ON]. Takeaway Motor (PL 14.7/PL
15.9) can be heard.
Y N
Check the Connection of P/J552 and P/J826. P/J826 and P/J552 are connected cor-
rectly.
Y N
Connect P/J552 and P/J826.
Measure the voltage between Tray Module PWB P/J552-2 (+) and GND (-), and P/J552-
5 (+) and GND(-) (BSD 8.2 Flag 1). The voltage is approx. +24VDC.
Y N
Replace the Tray Module PWB (PL 14.7/PL 15.9).
Replace the Takeaway Motor (PL 14.7/PL 15.9).
Check the paper transport drives and repair as required (PL 2.4, PL 14.7, PL 15.9).
