Abstract
A method and apparatus for locking the drive hubs of a forms overlay station in a laser electrographic printer to its transparent forms overlay drum includes counterboring a plurality of holes through the drum into the hubs, inserting a resilient member such as an O-ring into each counterbored hole, and compressing the resilient member to form an interference fit among the compressed resilient member and an interface formed within the counterbored hole by the drum and hubs.
