Abstract
Copy sheets having a re-fusable xerographic toner along an edge thereof are bound into booklets by arranging the sheets in a stack and re-fusing the toner so that the re-fused toner adheres adjacent sheets together. The re-fusing operation can be accomplished by a heating shoe and a patterned heating bar after each group of a few sheets is received from a copier so that the finisher operation can be carried on at the same rate copies are produced by the copier. Alternately, a larger stack of sheets can be bound together in an off-line basis by a simple heating step.
