Abstract
An electrophotographic printer is disclosed wherein the fusing of a toner image to an envelope by the use of a roll fuser causes the fusing nip to open early, i.e. the fusing nip opens a predetermined and controlled time/distance before the trailing edge of the envelope exits the fusing nip. As a result, creasing, wrinkling and the like of the envelope is minimized.
