073-101 Tray 3 Misfeed Jam RAP
BSD-ON:3.3/7.10/8.3
The Tray 3 Feed Out Sensor did not actuate in time after the Tray 3 Feed/Lift Motor energized.
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 good.
Y N
Replace the Transport Roll (PL 15.5).
Enter Component Control [073-103 Tray 3 Feed Out Sensor]. Actuate the Tray 3 Feed Out
Sensor (PL 14.6/PL 15.5) with paper. The display changes.
Y N
Check the connections of P/J821, P/J841, P/J548. P/J821, P/J841 P/J548 are con-
nected correctly.
Y N
Connect P/J821, P/J841, P/J548.
Check the wires between J821 and J548 for an open circuit or a short circuit (BSD 8.3
Flag 1/Flag 2/Flag 3 / BSD 8.5 Flag 1/Flag 2/Flag 3). The circuit between J821 and
J548 is conducting without an open circuit or a short circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between the Tray Module PWB P/J548-8 (+) and P/J548-9 (-) (BSD
8.3 Flag 2 / BSD 8.5 Flag 2). The voltage is approx. +5VDC.
Y N
Replace the Tray Module PWB (PL 14.7/PL 15.9).
Measure the voltage between the Tray Module PWB P548-10 (+) and GND (-) (BSD 8.3
Flag 1 / BSD 8.5 Flag 1).
Actuate the Tray 3 Feed Out Sensor (PL 14.6/PL 15.5) with paper. The
changes.
Y N
Replace the Tray 3 Feed Out Sensor (PL 14.6/PL 15.5).
Check the wires between J541-10 and J413-B4 for an open circuit or a short circuit (BSD
3.3 Flag 1). The circuit between J541-10 and J413-B4 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 P413-B4 (+) and GND (-) (BSD 3.3 Flag 1).
Actuate the Tray 3 Feed Out Sensor (PL 14.3/PL 13.5) with paper. The
changes.
Y N
Replace the Tray Module PWB (PL 14.7/PL 15.9).

A B
Replace the MCU PWB (PL 11.1).
Enter Component Control [073-002 Tray 3 Feed/Lift Motor ON]. The Tray 3 Feed/Lift Motor
(PL 14.3/PL 15.6) can be heard (the lifted paper plate drops when the tray is opened).
Y N
Check the connections of P/J220B, P/J661B, P/J549. P/J220B, P/J661B, P/J549 are
connected correctly.
Y N
Connect P/J220B, P/J661B, P/J549.
Remove the Tray 3 Feed/Lift Motor (PL 14.3/PL 15.6 and the Tray 2 Feed/Lift Motor (PL
14.3/PL 15.6).
Replace the Tray 3 Feed/Lift Motor with the Tray 2 Feed/Lift Motor.
Enter Component Control [073-002 Tray 3 Feed/Lift Motor ON]. The Tray 3 (2) Feed/Lift
Motor (PL 14.3/PL 15.6) can be heard (the lifted paper plate drops when the tray is
opened).
Y N
Return the Tray 2 Feed/Lift Motor to its original position.
Check the wires between P/J220B and P/J549 for an open circuit or a short circuit
(BSD 7.10 Flag 1 / BSD 7.12 Flag 1). The circuit between J220B and J549 is
conducting without an open circuit or a short circuit.
Y N
Repair the open circuit or short circuit.
Replace the Tray Module PWB (PL 14.7/PL 15.9).
Return the Tray 2 Feed/Lift Motor to its original position.
Replace the Tray 3 Feed/Lift Motor (PL 14.3/PL 15.6).
Enter Component Control [073-100 Tray 3 Pre Feed Sensor]. Actuate the Tray 3 Pre Feed
Sensor (PL 14.3/PL 15.6) with paper. The display changes.
Y N
Check the Connection of P/J103B, P/J661B and P/J549. P/J103B, P/J661B and P/
J549 are connected correctly.
Y N
Connect P/J103B, P/J661B and P/J549.
voltage
Check the wires between P/J103B and P/J549 for open circuit (BSD8.1 Flag 6/Flag 7).
The circuit between P/J103B and P/J549 is conducting without an open circuit or a
short circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between Tray Module PWB P/J549-30 (+) and
(BSD8.1 Flag 7). The voltage is approx. +5VDC.
Y N
Replace the Tray Module PWB (PL 14.7/PL 15.9).
voltage
Measure the voltage between Tray Module PWB P/J549-29 (+) and GND(-) (BSD8.1
Flag 6). Actuate the Tray 3 Pre Feed Sensor (PL 14.3/PL 15.6) with paper. The voltage
changes.
