Abstract
A method of forming a registration pattern to enable detection of registration errors in an image forming device includes forming a first registration mark on a substrate at a first image forming station, and partially erasing the first registration mark formed on the substrate at a second image forming station to form the registration pattern. A method of automatically detecting the registration errors further comprises sensing the registration pattern, and detecting registration errors based on the registration pattern.
