Abstract
This is a baffle used in a transfer station of an electrophotographic marking system. The baffle has a series of air passages that, when these passages are opened, they apply pressure to a sheet of paper and push it upward against a belt or drum surface of a photoreceptor or photoconductor. The toner imaged photoreceptor then transfers the image to the paper that is in contact with it. From the transfer station, the paper with the transferred image is then moved to the fuser station where the image is fused to the paper. The baffle with air passages does not scratch the photoconductor surface as do the prior art systems. Also, the baffle has a much longer useful life than the more costly lift finger transfer blades previously used. A controller senses when a sheet enters the transfer station, senses the paper size, then activates a number of air passages to match the paper size.
