Abstract
A method for minimizing toner usage in minimum area coverage patches in a color printer including: reviewing a print job including job images; performing a pixel count for each color plane on a sheet level of the print job; converting the pixel count to a percent area coverage per color plane; in feed-forward mode comparing the area coverage per color plane to a reference value; activating or inactivating a color station depending on the comparison of the area coverage per color plane to the reference value; and printing a MAC patch of variable size with the color station if the area coverage per color plane is substantially less than a reference value.
