ABSTRACT:
A four color toner single pass color printing system consists generally of a raster output scanner (ROS) optical system and a quad-level xerographic unit and a tri-level xerographic unit in tandem. The resulting color printing system would be able to produce pixels of black and white and all six primary colors. The color printing system uses a black toner and toners of the three subtractive primary colors or just toners of the three subtractive primary colors.
