Abstract
An electrophotographic printing machine is provided having an endless photoreceptor belt arranged to move in a predetermined path through a plurality of processing stations. The apparatus is used in conjunction with a method for automatically and repeatedly measuring and updating a steering coefficient used in an automatic steering mode. The method includes centering the belt and finding the average 'in' belt walk and 'in' belt walk rate and the average 'out' belt walk and 'out' belt walk rate, in order to determine the steering control coefficient. The method allows for a single machine to have its steering coefficient repeatedly updated.
