4085-001

Paper feed pick assembly does not feed, paper feed pick motor does not turn

Note: A noisy or chattering motor or a motor that fails to turn can be caused by:

	•	A defective motor
	• A bind in the paper feed mechanism
	•	Defective gears
	•	Defective engine board
	•	Defective power supply
	FRU		Action
1	Power Supply		Check the power supply. See the “Power Supply
			Service Check” on page 2-63 . If the power supply
			voltage is incorrect, replace the power supply.
2	Engine Board		Disconnect (J6) from the engine board. With the
			power on, check the voltage between pins 6, 10,
			and ground. The voltage at pin 6 should be
			approximately +35 V dc. The voltage at pin 10
			should be approximately +5 V dc. If either of these
			readings are incorrect, replace the engine board.
			Check continuity between (J2) on the RIP card
			and (J14) on the engine board. If correct, replace
			the engine board. If incorrect, go to step 3.
3	Paper Feed Pick		Disconnect (J6). Check between 6 and 7 on the
	Motor		connector for approximately 27.8 ohms. If reading
			is incorrect, replace the paper feed pick motor
			assembly. If reading is correct, check the
			continuity between each 6 and 7 to the motor
			case. If continuity exists, replace the paper feed
			pick motor assembly.
	Index Motor		Check the index motor connector J16 pin 2 to
			ground for approximately 27 volts. If voltage is
			incorrect, replace the system board. If reading is
			correct, check the continuity. See “Index Motor
			Service Check” on page 2-56 . If symptom
			remains, go to step 4.
			Note: If a short exists in the paper feed motor,
			damage to the engine board drivers and power
			supply may occur.
4	Tray 1 Sensor		See “Tray 1 Sensor Test” on page 3-27 . If test
	Check		fails, replace sensor.
