  • Publication number: 20100017706
    Abstract: What is provided is a system and method for resizing documents, for example, from legal size to a standard size. Document sizes are changed by adding or decreasing an amount of white space between lines of text. In one example embodiment, a multi-page document having a specified displayed page size is received. The multi-page document includes a plurality of text lines having respective specified font sizes and respective inter-line spacing. An inter-line spacing value within the current page is determined. The inter-line spacing value within the current page is reduced by a difference in size between the specified displayed page size and a target displayed page size. The font size of the document is retained. If the document size, after changing the amount of white space between lines, still exceeds a predetermined amount, an image magnification technique is used to complete the change in document size.

  • Patent number: 5732306
    Abstract: A method and apparatus for accurately and quickly enabling a technical representative to diagnose the source (or identify the component(s)) that is the root cause of the motion quality defect being experienced to reduce down time of the printing machine. The output of an encoder on the photoreceptor, electronically measured, translates variations in the photoreceptor velocity into voltage. The voltage is then converted into frequency, using a Fast Fourier Transform, for comparison to a predetermined set of frequencies associated with defective drive components to identify the source of the motion quality defect.

  • Patent number: 4814296
    Abstract: A process for forming individual dies having faces that allow the dies to be assembled against other like dies to form one and/or two dimensional scanning arrays wherein the active side of a wafer is etched to form small V-shaped grooves defining the die faces, relatively wide grooves are cut in the inactive side of the wafer opposite each V-shaped groove, and the wafer cut by sawing along the V-shaped grooves, the saw being located so that the side of the saw blade facing the die is aligned with the bottom of the V-shaped groove so that there is retained intact one side of the V-shaped groove to intercept and prevent cracks and chipping caused by sawing from damaging the die active surface and any circuits thereon.

  • Patent number: 4469319
    Abstract: In a sheet stacking apparatus, especially a recirculating document handler for recirculating document sheets for precollation copying at a copier platen to and from a stack in a document tray without obstructing access to the document tray, with restacking edge guides repositionable to accommodate stacking different sheet sizes and a restacking feeder for restacking the document sheets in the tray within the restacking edge guides by feeding each document in over the top of the stack from one edge and releasing the document to restack, there is provided automatically varying corrugation restacking apparatus enabling controlled restacking for recirculative copying of large flimsy documents such as Japanese B4 size sheets compatibly with normal document sizes having sheet corrugating members repositioned by movement of a repositionable restacking edge guide into a position to restack such large sheets and automatically providing in coordination therewith additional sheet corrugation in response to the flimsines
