Abstract

Disclosed is a 1ife-extending system for a document transport belt for a copier. The initial starting or registration position of the web or belt is sequenced periodically, thus shifting and distributing the maximum wear areas along the web. This can be accomplished with a belt having encoding indicia, e.g., cursors or hole patterns on the edge of the web, which indicate an initial starting position on the document belt and further indicia spaced along the belt in steps. The functional or actual starting position of the belt can be indexed away from this fixed position by

Disclosed is a 1ife~extendingsystem for a document transport belt for a copier. The initial starting or registration position of the web or belt is sequenced periodically, thus shifting and distributing the maximum wear areas along the web. This can be accomplished with a belt having encoding indicia, e.g., cursors or hole patterns on the edge of the web, which indicate an initial starting position on the document belt and further indicia spaced along the belt in steps. The functional or actual starting position of the belt can be indexed away from this fixed position by

one or more of said indicia steps per day. This can be done by sequencing the copier controller logic in response to each turn off of the main power supply of the machine. This functional (changing) starting position can be incremented sequentially along the belt out to another indicia position and then returned incrementally to the initial position. Such a system is particularly desirable in a

document handling system where registration fingers engage the document belt for document registration before the belt is moved into an imaging area, for example,
