	FRU / Function	Action
4	System Board	Execute the “Clean Print Nozzle” in “Cartridges” of
		the Printer Control Program. Look for a break in
	Printhead Cable	the diagonal line of the test pattern. A broken line
	Rubber Backer	indicates one or more print nozzles are not
		working. Run the test again to verify the failure. If
		there are even breaks in the diagonal line similar to
		the pattern shown below, ensure the printhead
		cables are connected properly. If the symptom
		remains, replace the system board.
		If there is a single break or random breaks in the
		diagonal line check the following:
		• Check the gold-plated contacts, on the end of
		the cable that connect to the carrier, for dirt and
		wear. Use only a clean dry cloth to clean the
		contacts. Also check the cable for damage. You
		may need to remove the cable from the carrier
		to inspect it.
		• A worn rubber backer results in poor contact
		between the printhead cable and the print
		cartridge. Check the rubber backer for wear.
5	Maintenance	Intermittent nozzle failures can be caused by worn
	Station	parts in the maintenance station. Perform the
		“Maintenance Station Service Check” on
		page 2-7, then return to this check.
6	Paper Feed	Ink smudging and smearing can be caused by
		paper problems or problems in the paper feed
		area.
		Check the following:
		• Correct type of paper is being used. Also check
		the paper for curl or wrinkles.
		• Feed rollers for wear, dirt, or looseness.
		• Gears for wear or binds.
		• Paper path for obstructions.
