Abstract: A low cost, high speed, high resolution laser printer method and apparatus for re-writable media is presented. A method for finishing of printed sheets into booklets is described. Novel mechanical operations permit the manufacture of a very low-cost, off-line booklet maker for use with desktop laser and ink jet printers. The technology can scale to medium-speed, in-line booklet manufacture. The method is novel because most of the finishing operations are performed on a sheet-by-sheet basis using precision paper positioning and a transverse tool carrier that cuts, scores, folds, punches, and staples the sheets. To form a finished saddle-stitched booklet, each sheet is cut to length determined by its sequence in the booklet and paper thickness, scored, punched (if required), folded, accumulated in a stack, and stapled. The sheet-wise method allows finishing operations to be done with low-cost tools and low actuation forces.
