	FRU	Action
1	Lower Duplex	Check the voltages on the duplex lower unit
	Unit Reverse	reverse sensor on CN907.
	Sensor (S4)	Pin #		Voltage	Voltage	Voltage
				Signal	Closed	Open
		1 (Red)		VL	+5 V dc	+5 V dc
		2 (Yellow)		RVSN	+5 V dc	0 V dc
		3 (Green)		DGND	0 V dc	0 V dc
		All voltages are approximate values.
		•	If the voltage on pin 1 is incorrect, replace the
			duplex option controller board.
		•	If the voltage on pin 2 does not change when
			the sensor is opened and closed, replace the
			FRUs in the following order:
		1.	Duplex lower unit reverse sensor
		2.	Duplex option controller board
2	Lower Unit	Check the voltages on the duplex lower unit paper
	Paper Feed	feed sensor on CN905.
	Sensor (S5)	Pin #		Voltage	Voltage	Voltage
				Signal	Closed	Open
		5 (Red)		VL	+5 V dc	+5 V dc
		6 (Blue)		POSN	+5 V dc	0 V dc
		7 (Green)		DGND	0 V dc	0 V dc
		All voltages are approximate values.
		•	If the voltage on pin 5 is incorrect, replace the
			duplex option controller board.
		•	If the voltage on pin 6 does not change when
			the sensor is opened and closed, replace the
			FRUs in the following order:
		1.	Duplex lower unit paper feed sensor
