Abstract
An electrostatographic reproduction machine including a media assembly for supplying and moving toner image receiving media passed a toner image transfer device; a fusing apparatus for heating and fusing a toner image on the toner image receiving media; and an imaging assembly for forming and transferring a toner image onto the toner image receiving media. The imaging assembly includes an endless photoreceptor belt having an imageable surface for forming the toner image, and a conicity reducing belt support and moving subassembly for supporting and moving the endless photoreceptor belt. The conicity reducing belt support and moving subassembly includes (i) a moveable steering roll for moving in a first direction into the endless photoreceptor belt and in a second direction along an inner surface of the endless photoreceptor belt, and (ii) a moveable tensioning roll for moving in a third direction into the endless photoreceptor belt and in a fourth direction along the inner surface of the endless photoreceptor belt, thereby reducing belt conicity and belt wrinkle, and increasing belt lateral registration.
