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 nonuniform nip and a uniform nip velocity.
