Abstract

Corona generators are used in electrophotographic machines for various purposes including the charging of the photoconductive material. Ozone generated by the corona must be removed for safety and the generator wires kept clean from dust in order to prevent streaks on copies. This article shows a corona design in which ozone ducts are included between the mounting rails and the corona shield with a flow of air which curtains the corona wire from contamination. As shown in the figure, clean air is drawn into the corona, through the end blocks 7 under the influence of a vacuum attached to exit ports 6. The clean air advances into the emission area 4 of the corona and into the ozone ducts 3 on either side of the corona.
