  • Publication number: 20050024689
    Abstract: Systems and methods for implementing a retail transaction at a digital image forming device are disclosed. Paper and blank electronic media may be purchased at the digital image forming device. The electronic media includes CD-ROMs, DVD-ROMs and floppy disks. A computer file may be transferred to the storage media as part of the transaction. The file may be transferred from any external electronic media. The file may be transferred from any storage media controlled by a portable digital device, such as a digital camera, a cell phone, a portable computer or a PDA. Alternately, the file may be transferred from a remote storage device accessible via the Internet to either media sold at or external to and in communication with the digital image forming device.

  • Publication number: 20020039441
    Abstract: A method and apparatus for selecting colors for blocks for use in a Block truncation Coding scheme is disclosed. The method includes finding the largest cluster of pixels and selecting that color for the first color in the block. The average color of the remaining pixels is assigned to the second color. The invention may be applied in iterative fashion if more than two colors are to be assigned to the block.

  • Patent number: 5755399
    Abstract: In a document feeding system for unfolding and feeding an elongated web multi-sectional computer form (CF) document from one end of a fan-folded stack in a document input stacking area to an imaging station, a CF document unfolding assistance system is provided by a mounting system cantilever mounting from behind the fan-folded stack a single smoothly radiused cylindrical CF unfolding assistance bar, with a radius of approximately 5 to 8 mm, rotatable between a completely non-obstructing rear storage position and a stationary operating position overlying the document input stacking area, and with a detent system for detaining the CF unfolding assistance bar in the operating position, in which this CF unfolding assistance bar is in a fixed position spaced intermediately above the CF web stack by about 5 cm and extending horizontally over the stack substantially perpendicular to the feeding direction in a position which is spaced closer to the one end of the stack than its opposite end, approximately 11 cm from

  • Patent number: 5757345
    Abstract: An electrocapillary color display sheet is disclosed which utilizes a plurality of sets of different color droplets between two sheets in which each set of droplets will create a pixel of an image. Each set of droplets has at least two droplets in which each droplet has a different color. Each droplet of each set is immiscible with the rest of the droplets of the set. There is an electrode on each sheet which corresponds to each set of droplets. There is also an addressable electrical connection to each droplet. By selectively activating droplets of each set of droplets and its corresponding electrodes on the two sheets, at least one of the droplets of the set will expand in a space commonly shared by the droplets of each set to create a colored pixel.

  • Patent number: 5635322
    Abstract: Disclosed is a process which comprises (1) providing a migration imaging member comprising a substrate and a softenable layer comprising a softenable material and a photosensitive migration marking material; (2) uniformly charging the imaging member; (3) subsequent to step (2), exposing the charged imaging member to activating radiation at a wavelength to which the migration marking material is sensitive; (4) subsequent to step (3), applying to the surface of the migration imaging member spaced from the substrate a substantially transparent overcoating layer and applying heat and pressure to the migration imaging member and overcoating layer, thereby causing the softenable material to soften and enabling the migration marking material to migrate through the softenable material toward the substrate in an imagewise pattern, while substantially simultaneously causing the overcoating layer to adhere to the imaging member surface.

  • Patent number: 5623721
    Abstract: An apparatus and method for cleaning triboelectric negative toner particles from the photoreceptor surface without the need of a preclean corotron. To remove the residual particles, a first cleaning brush, in the direction of motion of the photoreceptor, is negatively biased to remove the positive (+) toner and charge the toner particles negative. Then, the second brush, in the direction of motion of the photoreceptor, is positively biased to remove the residual negative toner particles from the surface as the second brush contacts the surface.
