ABSTRACT:
Method and apparatus for applying a periodic negative voltage to a coronode for the prevention of a streaming phenomenon in electrographic devices. A negative polarity voltage signal is applied periodically to the bare wire coronode of a positive corona charging device. The negative polarity voltage signal is believed to prevent the formation of streamer sites associated with the pepper tracking copy quality defect. The negative polarity voltage signal is applied to the coronode in a manner having a minimal effect on charging functions.
