5	Paper Trays and Options	Lists the size and type of media that is
		specified for each of the trays in the
		product. If a duplexing unit or any paper-
		handling accessories are installed on the
		product, information about those devices
		is also listed here.
6	Calibration Information	Lists the last color-plane registration
		(CPR) page count, the last CPR page-
		count date, the last page count (in engine
		cycles) for DMAX/DHALF, and the last
		DMAX/DHALF page-count date.
		Color plane registration occurs when
		new print cartridges are installed to
		compensate for any slight variations that
		might occur in cartridge circumference.
		DMAX is a density calibration of each
		print cartridge color at 100% coverage;
		DHALF is also a density calibration of
		each print cartridge color, but as a
		halftone instead of a full color. During
		halftone printing, the dots of toner are
		spread out, and coverage of the toner is
		less than 100%.
7	Color Density	Lists the cyan, magenta, yellow, and
		black (CMYK) values for highlights,
		midtones, and shadows.
