4059-XXX

Configuration 1

A level 1 fuser board and level 1 engine board are installed in configuration 1.

Note: Check the fuser envelope conditioner solenoid adjustment as described in the adjustment section “Fuser Solenoid Adjustment” on page 4-3.

	FRU	Action
1	Fuser Envelope Conditioner	The operation of the fuser solenoid
	Solenoid	can be observed by removing the
		redrive assembly. Check for proper
		mechanical operation of the solenoid
		and associated hardware, link and so
		on. If correct, check the resistance of
		the solenoid between J4-1 and J4-2.
		The resistance measures between 5
		ohms and 10 ohms. If incorrect,
		replace the solenoid assembly.
2	Fuser Control Board	The solenoid receives power from the
		fuser control board. The fuser control
		board receives +42Vdc from the LVPS
		via the interconnect board and
		envelope conditioner cable. Check for
		approximately +42 V dc at the
		+42 V dc test point on the fuser control
		board. If the voltage is correct, replace
		the fuser control board.
