ABSTRACT:
An electrostatographic copier or printer includes front end apparatus for forming and developing copies of images electrostatically, and back end apparatus which include a multiple function fusing roller that also functions as an image transfer roller. The multi-function fusing apparatus selectively includes a contact fusing operation or a non-contact fusing operation. A vacuum roller holds the copy sheet while either a radiant fuser or a pressure nip fuser will fix a toner image onto the substrate. The vacuum roller may be internally heated and the pressure roller which creates the fusing nip is selectively moved into and out of contact with the vacuum roller dependent upon the operation selected.
