Abstract
An electrostatographic reproduction machine including a contact belt fusing apparatus for fusing copy sheets without belt skew defects. The fusing apparatus includes an endless fusing belt having an external fusing surface defining a path of movement and a plurality of support rollers for supporting and moving the endless fusing belt along the path of movement. The endless fusing belt as supported has a preferred fusing position properly aligned on the plurality of support rollers. The fusing apparatus includes a pressure roller forming a fusing nip with the external fusing surface of the endless fusing belt for contacting and moving toner image carrying sheets therethrough. Importantly, the fusing apparatus also includes a dual function belt deskewing and oiling assembly for oiling the external fusing surface of the endless fusing belt and deskewing the fusing belt from a sensed skewed position to the preferred fusing position. The dual function belt deskewing and oiling assembly includes an oiling roller for contacting and oiling the fusing belt, and skewing means for skewing the oiling roller to controllably move the endless fusing belt in a deskewing manner from a sensed skewed…
