stray toner	216 g/m2 bond), you must select Heavy Paper as the

	collected on the transfer belt will cause smudging on
	the back of a page. The belt is self-cleaning and the
	smudging will normally clear within a few pages. Or,
	open and close the front door to complete a printer
	self-cleaning cycle.
	You recently had a media jam or the printer fed multiple
	sheets of media. Open and close the front door to
	complete a printer self-cleaning cycle.
	You are refeeding media that has already passed
	through the printer or through a copier. Do not refeed
	media. Refeeding media contaminates the fuser,

	printer control panel display for any messages. If no
	messages appear, print a configuration page to check
	the life of the consumables. Replace any consumables
	that are past their rated life.
