071-100 Tray 1 Pre Feed RAP
BSD-ON:7.7, 8.1
A sheet did not actuate the Tray 1 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 [071-001 Tray 1 Feed/Lift Motor
ON]. The Tray 1 Feed/Lift Motor (PL 2.3) energizes).
Y N
Check the connections of P/J201, P/J611 and P/J424. P/J201, P/J611 and P/
J424 are connected correctly.
Y N
Connect P/J201, P/J611 and P/J424.
Remove the Tray 1 Feed/Lift Motor (PL 2.3 and the Tray 2 Feed/Lift Motor (PL 14.3/
PL 15.6).
Replace the Tray 1 Feed/Lift Motor with the Tray 2 Feed/Lift Motor.
Enter Component Control [071-002 Tray 1 Feed/Lift Motor ON]. The
Feed/Lift Motor 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/J201 and P/J424 for an open circuit or a short cir-
cuit (BSD 7.7 Flag 1). The circuit between J201 and J409 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).
Return the Tray 2 Feed/Lift Motor to its original position.
Replace the Tray 1 Feed/Lift Motor (PL 2.3).
Repeat the code and check that the Feed Rolls are rotating. Repair the drives as required
(PL 2.3, PL 2.4).
There is a sensing problem. Enter Component Control [071-100 Tray 1 Pre Feed Sensor].
Actuate the Tray 1 Pre Feed Sensor (PL 2.3) with paper. The display changes.
Y N
Check the Connection of P/J133, P/J611 and P/J424. P/J133, P/J611 and P/J424
are connected correctly.
Y N
Connect P/J133, P/J611 and P/J424.

A B
Check the wires between P/J133 and P/J424 for open circuit (BSD 8.1 Flag 2/Flag 3).
The circuit between P/J133 and P/J424 is conducting without an open circuit or a
short circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between MCU PWB P/J424-A15 (+) and P/J424-A13(-) (BSD 8.1
Flag 3). The voltage is approx. +5VDC.
Y N
Replace the MCU PWB (PL 11.1).
Measure the voltage between MCU PWB P/J424-A14 (+) and GND (-) (BSD 8.1 Flag 2).
Actuate the Tray 1 Pre Feed Sensor with paper. The voltage changes.
Y N
Replace the Tray 1 Pre Feed Sensor (PL 2.3).
Replace the MCU PWB (PL 11.1).
Check the installation of the sensor and associated components (PL 2.3, PL 2.4)
