Abstract
In an electrostatographic copier wherein the fuser rolls are positioned closer than the dimensions of the copy sheet from the image transfer area, speed mismatch compensation between the fuser roll nip and the initial image support surface is provided by intentionally driving the fuser roll nip at a different velocity to form a buckle in the intermediate portion of the copy sheet controlled by selective cyclic reductions in the vacuum applied to a configured manifold guide surface. The guide surface may be divided into segments, through one of which the vacuum is continuously maintained.
