Reversing Roller Service Check

1	Gears	Check for, and replace any broken or worn gears.
2	Reversing	Unplug J14 of the reversing solenoid. Measure the
	Solenoid, SL7	resistance between J14-1 and J14-2 on the
	(4-20)	solenoid side. If it does not read 125 Ohms, replace
		the reversing solenoidm (PN 11D0114).
3	Paper Feed	Set the DIP switch (SW1) on the finisher driver
	Motor, M1 (4-	board so that 3 is on. Press the push switch (SW3)
	43)	to execute mechanical checking. If the paper feed
		motor does not rotate, replace it (PN 11D0118).
4	Finisher Driver	If there is still a problem, replace the finisher driver
	Board	board (PN 11D0294).

1	Connectors	Be sure J7, J9, and J10 are properly connected to
		the finisher driver board.
2	Shutter Close	Unplug J7 from the finisher driver board. Measure
	Detection	the resistance between J7-1 and J7-2 on the switch
	Sensor, PI-5	side. If it does not measure infinity with the shutter
	(2-23)	down, replace the shutter close sensor
		(PN 11D0071).
3	Shutter Open	Measure the voltage between J9-8 and J9-9 on the
	Detection	finisher driver board. If it is not 0 V with the shutter
	Sensor, PI-5	up, or not approximately 5 V with the shutter down,
	(2-23)	replace the shutter open sensor (PN 11D0071).
4	Finisher Driver	If there is still a problem, replace the finisher driver
