Test the voltage to the Tray 5 Back Latch sensor (SN106) on the Tray 5 Distribution PCA (A101)
1. Test the voltage to SN106 on A101: Tray 5 unlatched: 1.19 Vdc both blocked and unblocked at pins 8B to 6Bon W103P103-
A101J3 . Tray 5 latched: 1.0VDC at pins 8B to 6B on W103P103-A101J3 and 0.09 vdc unblocked, 4.91 vdc blocked at pins
1B to 6B on W103P103-A101J3.

Test the voltage to the Tray 5 Back Latch sensor (SN106) on the Motion PCA (A2)
1. Verify that J3 is connected on the Tray 5 Distribution PCA (A101).
2. Remove the power supply from the MFP, and then electrically reconnect the power supply outside of the MFP.
3. Test the voltage to SN106 on A2: 3.8 Vdc on J13 pins 22 to 13, 14, 37, and 38 (GND) and 5 Vdc on pins 15 to 13, 14, 37, and
38 (GND).
