Abstract

In duplex copying operations, it is often found that nudger rolls cause smears to be produced on copy sheets as a toned image on one copy sheet is slid over the second (blank) side of another sheet in the duplex tray. To reduce that smearing, the surface structure of the toned image is modified by smoothing rollers after the image has been fused. The smoothing rollers increase the gloss of the image and are aligned with the nudger rolls so that the smoothing of the image surface is localized to those regions in which smearing is likely to occur. The smoothing rollers could be part of a post-fuser transport system: for example, they could act as transport rollers themselves or they could be part of a decurler. The plurality of smoothing rollers producing localized smoothing of the image is less expensive and less likely to give rise to paper handling problems than a single large smoothing roller acting over a whole page width.
