  • Sheet handling apparatus
    Patent number: 4801135
    Abstract: An apparatus in which the loading and unloading of sheets on a tray used in a printing machine is facilitated. The uppermost sheet of the stack of sheets on the tray is continuously maintained at a preselected level as additional sheets are loaded on the tray or removed therefrom. This optimizes the operator access level and minimizes the delay time associated with the tray moving from the sheet feeding position to the operator access level.

  • Development apparatus
    Patent number: 4771311
    Abstract: An apparatus in which a latent image is developed with marking particles. In one mode of operation, the marking particles advance to the latent image. In another mode of operation, the marking particles are diverted from the latent image to prevent development thereof. A system of this type is particularly useful in color electrophotographic printing wherein successive electrostatic latent images are developed with different color marking particles.

  • Apparatus for positioning a photoconductive belt for development
    Patent number: 4769671
    Abstract: An apparatus in which a tubular member mounted on a shaft moves linearly in response to rotation of the shaft. A cam is mounted on the shaft and in engagement with bearings mounted on the interior surface of the tubular member. As the shaft rotates, the cam moves in unison therewith to move the tubular member linearly. The linear movement of the tubular member moves a portion of a photoconductive belt between an operative position, adjacent a developer unit, and an inoperative position, spaced from the developer unit.

  • Liquid carrier recovery system
    Patent number: 4766462
    Abstract: A reproducing machine in which an electrostatic latent image recorded on a photoconductive member is developed with a liquid developer material comprising at least a liquid carrier having pigmented particles dispersed therein. The developed image is transferred from the photoconductive member to a sheet of support material. The sheet of support material, with the developed image thereon, passes through a housing. In the housing, heat and pressure are applied to the sheet of support material to vaporize the liquid carrier and to fuse the pigmented particles to the sheet of support material in image configuration. An interior surface of the housing is cooled to liquefy the vaporized liquid carrier thereon.

  • Highlight color printing
    Patent number: 4761669
    Abstract: An electrophotographic printing machine in which indicia are printed on a sheet in at least two different colors. An electrostatic latent image is recorded on a photoconductive member and developed with a liquid developer material of one color. The latent image is neutralized and ions projected onto the photoconductive member in an image wise pattern to record another latent image. This latent image is developed with a liquid developer of another color. Both liquid images are transferred substantially simultaneously to a sheet to print indicia in two colors thereon.

  • Sheet guide
    Patent number: 4751547
    Abstract: An apparatus in which a range of differing weight copy sheets are advanced from a processing station of an electrophotographic printing machine. At the processing station, developed images are transferred from a moving image bearing member to copy sheets. The copy sheets are separated from the image bearing member with a light weight copy sheet being separated from the image bearing member at a first position. Heavier weight copy sheets are separated from the image bearing member at other positions. The first position is after the other positions in the direction of movement of the image bearing member. A guide is provided for guiding the heavier weight copy sheets onto the sheet transport with the light weight copy sheet being received on the sheet transport without contacting the guide.

    Patent number: 4745432
    Abstract: A reproducing machine in which an electrostatic latent image recorder on a photoconductive member is developed with a liquid developer material comprising at least a liquid carrier having pigmented particles dispersed therein. The developed image is transferred from the photoconductive member to a sheet of support material. The sheet of support material, with the developed image thereon, passes through a housing. In the housing, heat and pressure are applied to the sheet of support material to vaporize the liquid carrier and to fuse the pigmented particles to the sheet of support material in image configuration. A substantially portion of the vaporized liquid carrier and heated air are removed from the interior of the housing.

  • Sheet transport and registration apparatus
    Patent number: 4744555
    Abstract: An apparatus in which a sheet is registered during the movement thereof. The sheet is moved along a path in a forward direction of movement and a lateral direction of movement substantially normal thereto. The lateral movement of the sheet causes the side edge of the sheet to engage a registration edge so as to be aligned thereat. The magnitude of the moving force applied on the sheet is proportional to the thickness of the sheet. In this way, the moving force varies as a function of the thickness of the sheet with the sheet slipping laterally when engaging the registration edge to prevent buckling thereof.

  • Transport having compensation for material packing
    Patent number: 4743936
    Abstract: An apparatus in which particles are moved from one end of a duct to the other end thereof. The particles in the duct are fluidized. A pressure differential is generated which moves the fluidized particles in the duct from one end of the duct to the other end thereof. When the particles pack and cake together, the apparatus automatically moves the toner particles away from the region of the packed and caked toner particles to relieve this condition.

  • Intermediate transfer apparatus
    Patent number: 4743939
    Abstract: An apparatus in which a liquid image is transferred from a photoconductive member to a copy sheet. The liquid image, which includes a liquid carrier having toner particles dispersed therein, is attracted from the photoconductive member to an intermediate belt having a transfer liquid coated thereon. The transfer liquid has a higher viscosity than the viscosity of the liquid carrier. Liquid carrier is removed from the transfer liquid coated on the belt. Toner particles are transferred from the transfer liquid coated on the intermediate belt to the copy sheet in image configuration.
