Abstract
A printer having a color copy capability is enabled by scanning an original document having at least two discrete colored areas onto a color-filtered photosensor array simultaneously with formation of an electrostatic image of the original on a photoconductor member. The array generates output signals corresponding to detected color areas of the original document. These signals are sent to the printer software which determines the detected color image coordinates of each portion of the output copy. Output copies are then made, using multiple imaging erase and development passes.
