	for your project.

	If the paper you are using is too fibrous, the ink may not cover the print
	surface. Make sure you are using a paper that is appropriate for your HP
	Digital Copier.
	For more information, see recommended paper types on page 11.
	are you trying to copy newspaper or an original on thin paper?
	Copying a picture of poor quality, such as a newspaper photo, causes
	moiré patterns, such as bands, checks, or stripes, to appear.
	To reduce moiré patterns, try placing one or more clear plastic sheet
	protectors directly on the glass, and then place the original face down on
	top of the plastic sheet.
	do you need to clean the unit?
	Debris may be stuck on the glass or document lid backing, which causes
	poor copy quality and slows down processing. Unplug the unit before
	cleaning. Use a soft cloth to wipe the glass and document lid backing.
	For more information, see clean the glass and clean the lid backing on
	page 35.
