Abstract: An improved system for more accurately estimating consumption of toner imaging material in a digital xerographic printer in relation to a count of the digital pixels generating the various images being printed, where the frequency rates of the switching between print and non-print pixels are analyzed to provide weighting factors corresponding to different types of images being printed which affect the consumption of imaging material by the printer, and the pixel counts are weighted by these weighting factors to provide an imaging material consumption calculation based on image types as well as image pixel counts. The pixel count weighting factor is automatically substantially increased for the higher print/nonprint rates, or pixel on/off frequencies, and higher toner consumption by fringe field development, corresponding to halftone images in comparison to solid area images. The pixel count weighting factor is intermediately increased for intermediate imaging frequencies corresponding to normal line text.
