Abstract

A web edge sensor is disclosed. The web edge sensor has a light source directing light incident to an edge of a web. The edge of the web scatters the light and a sensor array that detects a first portion of the light scattered from the edge of the web and rejects a second portion to determine a position of the web edge.
