		1 (Brown)	PH3B-	+24 V dc	+22.0 to +25.5 V dc
		2 (Red)	VP	+24 V dc	+24 V dc

		• If the voltage on pin 2 measures approximately
		0 V dc, replace the option interconnect board.
		• If the voltages on Pins 1, 3, 4 or 5 are incorrect,
		replace the following FRUs in the order shown:
		1. Option paper feed motor
		2. Option interconnect board
3	Paper Feed Unit	If a 242 Paper Jam message displays, check
	Clutches CL2 or	clutch CL2. If a 243 Paper Jam message Clutches
	CL3	CL2 or CL3 displays, check clutch CL3.
	Option	Check the clutch cable for the failing tray to be
	Interconnect	sure it is installed properly.
	Board	Check the following voltages on CN803:
		Pin #	Signal	Voltage	Voltage
			Voltage	Static	Clutch Picked
		1 (Red)	VP	+24 V dc	+24 V dc
		2 (Black)	-SL6ON	+24 V dc	+24 V dc - 0 V dc
		3 (Red)	VP	+ 24 V dc	+24 V dc
		4 (Blue)	-SL7ON	+24 V dc	+24 V dc - 0 V dc
		All voltages are approximate values.
		If the voltages on pins 1 and 3 are incorrect,
		replace the option interconnect board.
		If the voltages on Pins 2 and 4 do not change,
		check the clutch by applying a ground to pin 2 for
		CL2, or pin 4 for CL3.

•If the clutch does not pick when the ground is applied to the pin, replace the clutch.

•If the clutch picks, replace the option interconnect board.
