Replace/reinstall the defective part(s).

Go to Step 2.

Power supply to the TRAY NO PAPER SENSOR

• Is the voltage level correct at the pins below? - P20-15PIN<=>P20-16PIN: 5VDC

Go to Step 3.

Go to FIP-2.1 "LVPS 5VDC is Defective".

Power supply to the TRAY NO PAPER detection signal

Is the voltage level correct at the pins below? - P20-17PIN<=>P20-16PIN: 5VDC

Go to Step 4.

Replace the MCU PWB.

Check: TRAY NO PAPER detection signal

• Is the voltage level correct depending on the conditions below?

- Blocked (no paper is set): 5VDC

Replace the MCU PWB.

Go to Step 5.

5

Check: TRAY N/P HARNESS electrical continuity

• Does the TRAY N/P HARNESS have proper continuity at the pins below? - J107<=>P101

Go to Step 6.

Replace the TRAY N/P HARNESS.

6

Check: P/H HARNESS ASSY electrical continuity

Does the P/H HARNESS ASSY have proper continuity at the pins below? - J101<=>J20
