Abstract

Proposed is a translating fuser that eliminates an image disturbance problem caused by the fuser operating slower than the process speed of an electrophotographic printing machine. Referring to the figure, the proposal replaces a conventional vacuum transport normally located between photoreceptor 24 and transfer station A comprising transfer corotron 26 and detack corotron 28. A vacuum shoe 20 is utilized ito isolate a transferred image from any motion disturbance caused by fusing station B. Vacuum shoe 20 is located downstream from transfer station A so as to acquire copy sheet 12. The vacuum shoe 20 directs copy sheet 12 to pass into a nip formed between fuser roller 16 and back-up roller 18, with a toner powder image contacting fuser roller 16. The rotational speed of fusing station B is approximately 2 to 3 percent slower than the velocity of copy sheet 12 to form a buckle 14 thereon. As copy sheet 12 enters fusing station B, fusing station B translates away from photoreceptor 24 to take up or control the magnitude of the buckle. When the trailing edge of copy sheet 12 clears photoreceptor 24 fusing station B slowly translates back to it's original position.

As copy sheet 12 enters fusing station B, fusing station B translates away from photoreceptor 24 to take up or control the magnitude of the buckle. When the trailing edge of copy sheet 12 clears photoreceptor 24
fusing station B slowly translates back to it's original position.
