Abstract
An apparatus and method for accurately establishing a predetermined gap between two surfaces, and in particular, between a corona generating device and a photoreceptive member in an electrostatographic printing machine, comprising a first conductive member for being mounted on a first of the two surfaces, a second conductive member for being placed on a second of the two surfaces, the combined thickness of the first and second conductive members being substantially equal to the predetermined gap. A device is coupled between the first and second conductive members, for sensing electrical continuity therebetween.
