		FRU		Action
	1	Fuser exit sensor (exit		Enter the Diagnostic mode, select BASE SENSOR TEST, select the
		sensor test)		Exit Sensor to test for proper operation. If the exit sensor fails the
				test, go to step 2. If the exit sensor passes, go to step 5.
	2	Fuser exit sensor cable		Check the fuser exit sensor cable for correct installation or for any
				signs of damage to the cable or connectors. If no problem is found,
				go to step 3. If a problem with the installation is found, install the
				cable correctly. If damage to the cable or connectors is found, replace
				the cable.
	3	Fuser exit sensor flag		Make sure the sensor flag is not binding and is operating properly. If
				the sensor is operating properly, go to step 4. If it is not operating
				properly, repair or replace the sensor assembly. See “Fuser exit
				sensor removal” on page 4-28.
	4	Fuser assembly		Check the continuity of the fuser exit sensor cable. If incorrect,
		Fuser exit sensor cable		replace the cable; if correct check the continuity of the fuser to
				system board cable. If incorrect, replace the cable; in correct, replace
		Fuser board
				the following FRUs in the order shown:
		Fuser to system board		• Fuser board.
		cable		• Fuser assembly. See “Fuser assembly removal” on page 4-26.
		System board
				• System board. See “System board and inner shield removal”
				on page 4-76.
	5			With the redrive assembly removed from the printer, enter the
				Diagnostics mode and run the print test from tray 1 (for example,
				select PRINT TESTS, Tray 1, and Continuous) and observe the
				media as it passes over the exit and narrow media sensors. Check
				that the sensor flags are operating correctly. If the sensor flags and
				hardware are operating incorrectly, repair or replace the failing
				sensor assembly. If no problem is found, check the fuser for any signs
				of media in the fuser or any signs of toner or other contamination. If a
				problem is found, clean or remove the debris or contamination.
