Tray 2: MCU PWB P412-9
Tray 3: TM PWB P548-14
Tray 4: TM PWB P548-7
The voltage is the specified value (MCU PWB: approx. +5VDC, Tray Module PWB:
approx. +3.3VDC).
YN
Replace the relevant PWB (MCU PWB (PL 9.1) or Tray Module PWB (PL 12.6/PL
13.8)).
Measure the voltage between the following points (+) and GND (-).
Tray 1: MCU PWB P412-1
Tray 2: MCU PWB P412-6
Tray 3: TM PWB P548-11
Tray 4: TM PWB P548-4
Activate SW5 of the relevant Size Sensor. The voltage changes.
YN
Replace the relevant PWB (MCU PWB (PL 9.1) or the Tray Module PWB (PL 12.6/
PL 13.8)).
Replace the relevant Size Sensor.
Check the connections of the following connectors:
Tray 1: P/J109, P/J412
Tray 2: P/J110, P/J412
Tray 3: P/J820, P/J548
Tray 4: P/J824, P/J548
The connectors are connected correctly.
YN
Connect the connectors.
Check the following harnesses for an open circuit or a short circuit.
Tray 1: Between J109 and J412
Tray 2: Between J110 and J412
Tray 3: Between J820 and J548
Tray 4: Between J824 and J548
The relevant harnesses are conducting without an open circuit or a short circuit.
YN
Repair the open circuit or short circuit.
Measure the voltage between the following points (+) and GND (-).
Tray 1: MCU PWB P412-4
Tray 2: MCU PWB P412-9
Tray 3: TM PWB P548-14
Tray 4: TM PWB P548-7
The voltage is the specified value (MCU PWB: approx. +5VDC, Tray Module PWB:
approx. +3.3VDC).
YN
Replace the relevant PWB (MCU PWB (PL 9.1) or Tray Module PWB (PL 12.6/PL 13.8)).
Measure the voltage between the following points (+) and GND (-).
Tray 1: MCU PWB P412-3
Tray 2: MCU PWB P412-8
Tray 3: TM PWB P548-13
Tray 4: TM PWB P548-6
Activate SW1 to SW4 of the relevant Size Sensor in sequence. The voltage changes.
YN
Replace the relevant Size Sensor.
Replace the relevant PWB (MCU PWB (PL 9.1) or Tray Module PWB (PL 12.6/PL 13.8)).
