Abstract

For cleaning a corotron wire in a xerographic machine, a ceramic disc may be used to shear off the contaminants by being slid down the wire. The disc may take the form of a cylinder having a bore extending therethrough. The inside diameter of the bore is selected to be only slightly greater than the outside diameter of the corona wire, so that as the disc slides along the length of the wire contaminants are sheared off. The disc may be made of a high density ceramic such as Alumina (AL203) which has good abrasion resistance, high hardness and very high electrical resistance. A sliding carriage may be employed to move the disc along the wire.
