073-100 Tray 3 Pre Feed RAP
BSD-ON:7.9, 7.11, 8.1
A sheet did not actuate the Tray 2 Pre Feed Sensor in time.
Initial Actions
Check that the paper path is free of foreign substances and sensors are free of paper dust.
Procedure
Run the machine to create the fault. Check if paper is partially fed from the tray. Paper is par-
tially fed from the tray (top sheet is shingled or moved slightly from stack).
Y N
There is a drives problem.
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,
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
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).
Repeat the code and check that the Feed Rolls are rotating. Repair the drives as required
(PL 14.1, PL 14.2, PL 15.6 PL 15.7).
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.
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).
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.
Y N
Replace the Tray 3 Pre Feed Sensor (PL 14.3/PL 15.6).
P/J661B, P/
Replace the Tray Module PWB (PL 14.7/PL 15.9).
Check the installation of the sensor and associated components (PL 14.1, PL 14.2, PL 15.6 PL
15.7)
