Julio A. Sanchez-Banos has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6560428
    Abstract: A tension and detensioning assembly includes a frame and a moveable tensioning roll for tensioning the continious loop belt. The moveable tensioning roll has an axis, a first end, a second end, a first position for tensioning the continous loop belt, and a second position when the continous loop belt is detensioned. When the moveable tensioning roll is in the second position, the first end is spaced a first distance from the first position, and the second end is spaced (from the first position) a second distance that is different from the first distance in order to enable safe, efficient and controlled, non-slipping removal and reinstallation of the flexible closed loop photoreceptor belt.

  • Patent number: 5761596
    Abstract: An alignment baffle for use in a printing apparatus having a conveying mechanism for conveying images toward an image transfer area and copy sheet chute for guiding copy sheets toward the conveying mechanism is provided. The images are transferred to the copy sheets in the transfer area. The baffle includes a body operably associated with the image transfer area and a first member connected to the body and spaced from the copy sheet chute. The first member has a first member surface for guiding the copy sheet. The baffle also includes a second member operably associated with the first member, connected to the body and spaced from the copy sheet chute. The second member has a second member surface for guiding the copy sheet. The first member and the second member have a passageway therebetween for passage of the copy sheets therebetween. The first member surface and the second member surface cooperate with the copy sheets to guide the copy sheets in a path tangential to the conveying mechanism.

  • Patent number: 5568238
    Abstract: An apparatus which transfers a developed image from a photoconductive surface to a copy sheet. The apparatus includes a corona generating device arranged to charge the copy sheet for establishing a transfer field that is effective to attract the developed image from the photoconductive surface to the copy sheet and a blade which is moved from a non-operative position spaced from the copy sheet, to an operative position, in contact with the copy sheet for pressing the copy sheet into contact with at least the developed image on the photoconductive surface to substantially eliminate any spaces between the copy sheet and the developed image during transfer of the developed image from the photoconductive surface to the copy sheet. The blade is fabricated to include a conductive material for preventing the generation of electrostatic charge on the blade which may create copy quality defects as a lead edge of the copy sheet passes between the blade and the photoconductive surface.

  • Patent number: 5475474
    Abstract: A wiper system for use in an electrophotographic printing machine having a variety of electrophotographic subsytems situated about a photoconductive member. The electrophotographic printing machine includes a slidable module for supporting a photoconductive member, the slidable module being movable relative to the electrophotographic subsytems such that the photoconductive member is retractably displaceable from the electrophotographic printing machine to provide access thereto. A wiper assembly, engaging with an exposed surface of at least one of the electrophotographic subsytems, is mounted on the slidable module such that the wiper means is slidably engaged with the exposed surface to provide cleaning action thereagainst in accordance with the slidable movement of the slidable module.

  • Patent number: 5450174
    Abstract: A lamp system for erasing an electrically charged photoconductive surface including an optically transmissive protective cover fabricated from a polypropylene adhesive tape for being affixed to a segmented surface so as to eliminate exposed gaps in which contaminants may collect and for providing a smooth surface which can be cleaned more efficiently and effectively.

  • Patent number: 5335050
    Abstract: An adjustable support assembly for adjustably supporting a corona generating device at a selected distance from a photoreceptive surface, wherein a fixedly mounted support bracket and an adjustable support bracket are mounted in a cooperatively nested relationship such that reciprocating movement can be affected between the adjustable support bracket and the fixedly mounted support bracket. The adjustable support assembly is provided with support blocks for adjusting the gap between the corona generating device and the photoreceptive surface from a single general location.
