Background scatter Background scatter results from bits of toner
		randomly distributed on the printed page.
	A	• The paper may be too damp. Try printing
		with a different batch of paper. Do not open
		packages of paper until necessary so that
		the paper does not absorb too much
		moisture.

		envelope, change the printing layout to
		avoid printing over areas that have
		overlapping seams on the reverse side.
