ABSTRACT:
A heat and pressure roll fuser is disclosed for fixing powder images to various substrates. Each of the rolls has a deformable outer layer. One of the rollers is crowned such that its center has a larger diameter than its ends. The other roller has a uniform diameter along its entire length. The difference in the center diameter and the end diameters is such that the fuser produces a substantially uniform nip and a uniform nip velocity. A flared pressure roll is provided for controlling the speed of substrate edges to compensate for waviness along the substrate edges, such waviness being due to moisture picked up by the substrates while being stored prior to being used for duplex imaging.
