Lexmark 4059-XXX manual Correct position on the engine board

4059-XXX

Configuration 2

A level I fuser board and level II engine board are installed in configuration 2.

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

	FRU	Action
1	Engine Board Jumpers	Check to make sure a jumper is
		installed between JP1-2 and JP1-3
		and also between JP2-2 and JP2-3 on
		the engine board.
		Note: If the jumpers are not in the
		correct position on the engine board,
		damage can result to the fuser board.
2	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 the resistance is
		incorrect, replace the solenoid
		assembly.
3	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 incorrect,
		replace the fuser control board.
