Abstract

A short paper path sheet support is proposed for a xerographic top transport architecture. The short paper path provides a means to guide a moving copy sheet (bearing an unfused image face down) between a photoreceptor and a fuser station. The copy sheet acts as a free cantilever beam to precisely contact the fuser nip. Heat is added to an air stream to initiate toner melting and thus eliminates a need to slow the fuser down.

SHORT PAPER PATH SHEET SUPPORT(Cont'd)

A short paper path sheet support is proposed for a xerographic top transport architecture. The short paper path provides a means to guide a moving copy sheet (bearing an unfused image face down) between a photoreceptor and a fuser station. The copy sheet acts as a free cantilever beam to precisely contact the fuser nip. Heat is added to an air stream to initiate toner melting and thus eliminates a need to slow the fuser down.

The short paper path is illustrated in the Figure. The trajectory of the copy sheet is shown as a paper path line 16. The copy sheet leaves a transfer area comprising a photoreceptor 32 and detacwtransfer corotrons 30. A copy sheet having an excessive upward lead edge curl contacts an upper guide baffle 20
having an angle A of approximately 20 degrees. The upper guide baffle 20
flattens the sheet and guides it downward, with minimum disturbance, to the fuser nip formed by a fuser roll 24 and a pressure roll 26. A flat copy sheet or one having a downward lead edge curl contacts a ramp and air stream plenum device 22. The ramp likewise has an angle A of approximately 20 degrees and allows the copy sh...
