  • Patent number: 8724155
    Abstract: A copier apparatus includes a scanner for acquiring at least one image to be copied. Temporary storage is adapted to temporarily store the image only until the next subsequent print/copy job is scanned. At least one printing engine is used to print the image on a medium. In addition, a processor is preset to delete the image from the temporary storage after completion of printing of the image by the printing engine unless the user interface has previously received an instruction to reprint the image. If the user provides an instruction to reprint the image, the user interface is adapted to display a menu of reprint options. Then the image can be reprinted without having to be rescanned.

  • Patent number: 5815787
    Abstract: A sheet stacking and lifting cassette tray assembly for reliably and effectively feeding sheets of different basis weight for use in a reproduction machine. The sheet stacking and lifting cassette tray assembly includes a cassette frame including a frame floor, and frame side walls; a plurality of sheet stacking and lifting subassemblies mounted within, and to, the frame side walls for applying selectable values of sheet lifting normal forces against a sheet feedhead. Each sheet stacking and lifting subassembly of the plurality of sheet stacking and lifting subassemblies includes a pivotable stacking and supporting plate, and a set of springs having a spring rate for providing a normal force having a particular value for lifting a stack of sheets.

  • Patent number: 5551686
    Abstract: In a networked or other shared users electronic printing system for printing plural print jobs of plural printed sheets of the different users, with a printer mailbox having a sheet distribution system for automatically directing and stacking into different individual mailbox bins, which are electronically assigned to different respective users, the respective print jobs of the respective users, a bin almost-full sensing system detects and signals that the stacking level of the printed sheets in the bin has reached a preset almost-full level which is less than the preset limited sheet full stacking capacity of the bin.

  • Patent number: 5225880
    Abstract: An agglomerate removal device for removing unwanted particles from images on a photoreceptor includes vacuum pick off source and baffles that create a controlled aerodynamic drag under the photoreceptor before the images reach a transfer station. Removing the agglomerates improves the quality of images transferred at the transfer station to receiving substrates.

  • Patent number: 4621801
    Abstract: A document feeder for feeding a document sheet in a document feeding path downstream to a registered copying position on the platen of a copier, with deskewing and edge registration (document registration transverse the direction of the document feeding path to the platen) upstream of the platen, with a skewed roller edge registration system for feeding the document transversely as well as downstream, and wherein a large radius non-skewed arcuate document guide path provides an arcuate document deforming portion of the document feeding path, the improvement wherein an arcuate document edge confinement and control is provided along the edge of the arcuate document guide path, preferably by a document edge guide having a narrow and smooth-bottomed arcuate slot adapted to receive, confine closely, and edge register the document therein, sliding it along the bottom of the slot, and the skewed rollers are mounted in and intermediately of the arcuate document guide path for providing both edge registration and desk

  • Patent number: 4579444
    Abstract: In a document feeder for a copier which transports a document sheet onto and over the platen of the copier and which places the document in a desired registration position on the platen for copying by stopping the document platen transport of the document feeder, and thereby stopping the document being fed thereby at the desired position, without the document hitting a mechanical registration stop, the improvement comprising a variable registration control system for controlling the document platen transport to stop at a desired calculated stopping position, including a sensor adjacent by a known fixed distance the upstream, entrance, side of the platen for sensing the trail edge of an individual document sheet being transported onto the platen by the document platen transport, providing a first signal indicative of the selected size of the copy sheet onto which that document sheet is to be copied, providing a second signal indicative of the optical magnification or reduction ratio with which that document is

  • Patent number: 4579326
    Abstract: In a copier with a recirculating document handler pivotally mounted to be closable over an imaging station on the upper surface of the copier, and a document inverter, and the capability of automatically copying both sides of documents at the imaging station by utilizing the document inverter to invert documents being recirculated by the document handler, the improvement wherein the document inverter is only partially in the document handler and operatively but non-integrally incorporates a generally planar document chute which is independently integrally mounted to the copier and is not a physical part of or pivotal with the document handler, to provide a more compact document handler with automatic document inversion capability, wherein the document chute is defined by upper and lower baffles for containing and guiding a document for reversal therein by the document inverter, and wherein at least a major portion of these upper and lower baffles are integral to the copier, laterally adjacent to both the imag

  • Patent number: 4579325
    Abstract: In a document handler for a copier for providing recirculative copying at the copier imaging station of plural documents stacked in a recirculative copying input tray with automatic inversion of duplex documents by a document inverter with a document inverting chute in the recirculative path of the documents, and with a document return path after this recirculative copying back to the input tray, and wherein this same document handler also has an integral alternative non-recirculative copying document input for non-recirculative document copying at the same imaging station, and a document output for this alternative document input for ejecting documents from the document handler after the non-recirculative copying, the improvement wherein the document inverting chute is substantially planer, and open ended, to provide for alternative unobstructed unidirectional document feeding therethrough, and the document inverter operates to reverse the direction of movement of documents in the inverting chute from the in
