024-965 ATS/APS Paper (IOT detect) RAP
BSD-ON:7.7/7.8/7.9/7.10/7.11/7.12
No paper is loaded in the tray.
Initial Actions
• Power Off/On
• Reload the relevant tray.
Procedure
Check the actuator of the relevant No Paper Sensor. The actuator is not distorted or dam-
aged.
Y N
Replace the actuator.
Actuate the actuator of the relevant No Paper Sensor.
Tray 1: Component Control [071-101 Tray 1 No Paper Sensor]
Tray 2: Component Control [072-102 Tray 2 No Paper Sensor]
Tray 3: Component Control [073-101 Tray 3 No Paper Sensor]
The display changes.
Y N
Check the connections of the following connectors:
Tray 1: P/J101, P/J611, P/J424
Tray 2: P/J102B, P/J661B, P/J549
Tray 3: P/J102A, P/J661A, P/J549
The connectors are securely connected.
Y N
Connect the connectors.
Check the following harnesses for an open circuit or a short circuit.
Tray 1: Between J101 and J424 (BSD 7.7 Flag 4/Flag 5)
Tray 2: Between J102B and J549 (BSD 7.8 Flag 4/Flag 5)
Tray 3: Between J102B and J549 (BSD 7.10 Flag 4/Flag 5)
The relevant harnesses are conducting without an open circuit or a short circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between the following points (+) and GND (-).
Tray 1: MCU PWB P424-A10 (BSD 7.7 Flag 5)
Tray 2: MCU PWB P549-25 (BSD 7.8 Flag 5)
Tray 3: TM PWB P549-10 (BSD 7.10 Flag 5)
The voltage is approx. +5VDC.
Y N
Replace the relevant PWB (MCU PWB (PL 11.1) or the Tray Module PWB (PL 14.7).
Measure the voltage between the MCU PWB P409A-12 (+) and GND (-).
Tray 1: MCU PWB P409A-12 (BSD 7.7 Flag 4)
Tray 2: MCU PWB P409B-12 (BSD 7.8 Flag 4)
Tray 3: TM PWB P549-A12 (BSD 7.10 Flag 4)

A
Activate the actuator of the relevant No Paper Sensor (PL 2.3, PL 14.3). The
changes.
Y N
Replace the relevant No Paper Sensor (PL 2.3, PL 14.3).
Replace the relevant PWB (MCU PWB (PL 11.1) or Tray Module PWB (PL 14.7).
For Tray 1, replace the MCU PWB (PL 11.1).
For Tray 2, or Tray 3 replace the Tray Module PWB (PL 14.7).
