ABSTRACT:
Corona electrodes in electrostatic copying machines take the form of a fine gauge wires, and when subjected to toner an atmosphere with a high density of particle dispersion, can become covered with a deposit which impairs their effectiveness. Cleaning of such a wire is situ without danger of injury thereto is effected by periodically inducing vibrations in the wire, either by controlled mechanical plucking, or by electromagnetically or electrostatically inducing vibrations.
