Random Marks Service Check

Note: Loose material moving inside the printer and attaching to the photoconductor, ITM Belt, or transfer roll, is the primary cause of random marks.

	FRU	Action
1	Random Marks	Check the print cartridges for signs of loose or
		foreign material that might be on the
		photoconductor.
		Check the ITM belt and transfer roll for material
		stuck to the belt or imbedded in the roll.

Residual Image Service Check

	FRU	Action
1	Print Cartridge	The print cartridges can cause a residual image
		due to a defective cleaning blade, photoconductor
		or other parts inside the print cartridge. Determine
		which cartridge is causing the problem.
2	Fuser Assembly	Check the fuser assembly for signs of toner
		contamination. The hot roll might retain toner
		deposit on the page.
3	Erase Lamp	If the cartridges and fuser assembly do not have a
	Assembly	problem, go to the “Erase Lamp Service Check”
		on page 2-50.
