Abstract

Scorotrons are commonly used as a primary charging device in xerographic printing machines due to their ability to consistently charge a receptor uniformly. A beneficial quality of scorotrons is their use of a screen to provide automatic feedback to shut off ions. For machines requiring longer and/or wider scorotrons, problems may arise concerning maintenance of screen flatness, in or orthogonal to a process direction. Without flatness control arcing possibilities and non-uniform charging may result. Disclosed is a corrugated screen with improved overall mechanical strength and flatness.
