ABSTRACT:
Fusing of a toned sheet of copy paper is accomplished by a fusing nip formed by a resilient hot roll and a rigid backup roll. The sheet is introduced to the fusing nip in a unique manner such that the sheet's initial contact to the hot roll fuser is substantially only a point on the sheet's leading edge. This is accomplished by orientation means operable to bow the sheet's leading edge, and/or to produce skew between the fusing nip and the sheet's leading edge.
