Abstract
A method for determining the position of media in a system where images are applied to the media at subsequent stations includes the steps of placing on the media at a first position tracking information consisting of a pattern of electrostatic charge to provide information with regard to the alignment of the media at the first station, and at the second station detecting the pattern of electrostatic charge to determine the alignment of the media at the second station. Typically the media consists of electrostatic paper and the step of placing charge on the paper is achieved by positioning positively charged styli in close proximity to the surface of the paper.
