ABSTRACT:
An electrostatic color printer incorporating an array of imaging electrodes controlled by special purpose integrated circuits, and a color drum having a charged multilayered particle screen to sequentially present color toners to the imaging array. The special purpose integrated circuits include low voltage, logic and memory circuits, high voltage circuits to drive the imaging electrodes and provide a direct path for the particles to the receiving print medium. The electrodes are arrayed to form a staggered linear array. The printer is capable of printing multiple colors with variable color density in each pixel position and the color image is printed with a single pass of the receiving print medium past the imaging head.
