Abstract
A belt-roll fuser system includes a belt-roll fuser apparatus wherein a belt is entrained about at least a first internal pressure roll and a second internal pressure roll. The first internal pressure roll and the second internal pressure roll are configured to force a belt against an external pressure roll at a fusing nip, the belt conforming to the external pressure roll across substantially a length of the fusing nip. A passive belt support may interpose internal pressure rolls for ensuring a consistent fusing pressure across the length of the nip. A pressure belt may interpose the fuser belt and the internal pressure rolls.
