Adjustment/Cleaning

Special Mode O	Sets whether to prevent paper jams when printing on the
	back of a printed paper.

	faint.
Medium	Paper separates easily from the cartridge, preventing paper
	jams.

	selected.
Off	Disables Special Mode O.
Special Mode P	Sets whether to prevent paper curls when using paper such
	as lightweight paper or recycled paper, which curls easily
	regardless of humidity.
	If both of the Special Mode N and Special Mode P settings are
	enabled, Special Mode N will prevail.
Off	Disables Special Mode P.

	size of paper required is different for a job that follows an
	extended amount of printing, there may be a waiting time
	before the next job starts.
	* If you set this mode to [Speed Priority 1] or [Speed Priority 2],
	a previously printed image may reappear faintly on the next
	printout.
