Abstract
A method and apparatus for a universal printhead is disclosed that functions independently of the diameter of a charge receiving dielectric drum, while optimizing print quality. The printhead includes two sets of electrodes mutually separated by a dielectric. Each of the electrodes from the first layer crosses each of the electrodes from the second layer forming a plurality of charge generating sites. The charge generating sites are generally disposed in only two rows.
