Abstract

Electrographic paper is fed over a segmented platen where its dielectric surface receives image defining electrostatic charges deposited by styli bearing directly and successively upon it. The styli are integral to an endless belt moving laterally to the surface. Voltage pulses corresponding to the input information are applied to the segmented platen to produce the electrostatic charges. The latent image charged surface is progressively fed to an image toning and fixing cycle to produce a hard copy.
