4076-0XX

	FRU OR PROCEDURE	ACTION
4	Maintenance Station	Intermittent nozzle failures can be
		caused by worn parts in the mainte-
		nance station. Go to and perform the
		“Maintenance Station Service Check”
		on page 12, then return to this check.
5	Paper Feed	Ink smudging and smearing can be
		caused by paper problems or prob-
		lems in the paper feed area. Check:
		• Correct type of paper is in the
		machine. Also check the paper for
		curl and wrinkles.
		• Feed roller for wear, dirt, or loose-
		ness
		• Gears for wear or binds
		• Paper path for obstructions
		• Star rollers for binds or dirt. The exit
		roller and star rollers keep tension
		on the paper by moving slightly
		faster than the feed rollers. A bind-
		ing star roller can put vertical marks
		on the paper.
6	Transport	Blurred print and voids can be caused
		by problems in the transport area.
		Check the following:
		• Transport belt for wear.
		• Carrier guide and carrier guide rod
		for wear or dirt.
		• Idler pulley parts for wear, damage,
		or looseness.
		• Encoder strip for wear or dirt.
7	BiDirectional Alignment	Uneven vertical lines can be adjusted
		by performing the “Bi-directional
		Alignment Adjustment” on page 31.
