On the 2232/2238's, in Auto Color Select Copy Mode, black pages prior to the first color page is true black. After a color page is done, all subsequent black pages are processed black created from print from all four color drums and development units. However, the hard meter that we all get from user tools will only show those pages as a black copy even though it was created using each of the colors.
The quality from the processed black pages are nowhere close to the quality of the true black pages.
