  • Patent number: 9937669
    Abstract: A three-dimensional object printer has a platen that is configured to facilitate the release of objects formed on the platen. The platen includes a first layer and second layer, the first layer having a coefficient of thermal expansion that is different than a coefficient of thermal expansion of the second layer. A controller in the printer is configured to operate at least one ejector in an ejector head to form a three-dimensional object on the surface of the platen with reference to digital image data and, upon completion of the object, to operate a temperature control device operatively connected to the platen to bend the platen by changing the temperature of the platen and releasing a three-dimensional object from the platen.

  • Patent number: 9804810
    Abstract: A method of operating a document finishing device is provided. The method includes installing first data relating to physical capabilities of the document finishing device in a document finishing device; connecting the document finishing device to a printer; copying the first data from the document finishing device to the printer; causing the printer to interpret the first data; and causing the printer to adjust its output capabilities based on the first data.

  • Patent number: 9597839
    Abstract: A printer compensates for printing errors occurring during production of the layers for the formation of an object in a three-dimensional printer. The printer includes an optical sensor that generates data corresponding to edges of each layer of the object after each layer is printed. Differences between the raster data used to eject the material to form a layer and the data received from the optical sensor are used to modify the raster data that operates a printhead to form a next layer in the object.

  • Patent number: 9381701
    Abstract: A three-dimensional object printer includes an actuator that contacts a surface of a platen in the printer. A controller selectively operates the actuator to apply force to a bottom layer of a three-dimensional object formed on the platen to break an adhesion between the bottom layer and the platen.

  • Patent number: 8739364
    Abstract: An apparatus includes a wheel having an axle, and a round disk connected to the axle. The round disk has a disk middle connected to the axle and a disk circumferential surface surrounding the disk middle. Further, a round ring having an inner ring surface is connected to the disk circumferential surface of the round disk. The round disk is positioned within the round ring. The round ring contacts the round disk along a first plane, and the axle is coplanar with the first plane. Additionally, the round ring has a ring circumferential outer surface having threads. A threaded cylinder having an inner threaded cylinder surface is connected to the threads in the ring circumferential outer surface. The round ring is positioned within the threaded cylinder. Further, a worm gear is positioned between the threaded cylinder and the round ring.

  • Patent number: 6857631
    Abstract: A sheet feeding system in which the idler roller shafts are loosely mounted between opposing side walls of a slot for limited movement relative to their mating sheet feeding rollers, and spring biased theretowards to provide sheet feeding nips with the desired normal force, wherein the spring biasing is nonsymmetrical to additionally provide an orthogonal spring biasing of the idler shafts towards only one of the side walls of their mounting slots. This nonsymmetrical spring biasing may be provided by a torsion spring with a central coil wrapped around the idler shaft and extending legs anchored in nonsymmetrical anchoring positions and/or with nonsymmetrically shaped legs.
