20080240791 | ELECTROGRAPHIC DEVELOPER MIXING APPARATUS AND PROCESS - A developer mixing apparatus, comprising: a housing including a chamber that holds developer, a first ribbon blender disposed within the chamber and elongate along a first longitudinal axis; and, a second ribbon blender disposed within the chamber and elongate along a second longitudinal axis, wherein the first and second ribbon blenders move developer in different directions. | 10-02-2008 |
20080241415 | POWDER COATING APPARATUS AND METHOD OF POWDER COATING USING AN ELECTROMAGNETIC BRUSH - Apparatus and methods for applying powder coatings to a substrate using a magnetic brush developer, including a method and apparatus for applying powder coatings to a substrate either directly or by intermediate transfer using a magnetic brush with a rotating magnetic field and for preparing the coating materials. The apparatus and method includes a supply of prepared powder coating material, a magnetic brush having a rotating magnetic field for applying the powder coating material to the substrate; and an electric field between the magnetic brush having a rotating magnetic field and the substrate. | 10-02-2008 |
20090052914 | METHOD AND SYSTEM FOR WIDE FORMAT TONING - A printer or other powder deposition device may include multiple toning stations, and the toning stations may be positioned in various configurations within the device. The various configurations may position the toning stations so as to increase the toning width of the device, thereby allowing the device to print larger process widths. The device may also perform processing control for the multiple toning stations. | 02-26-2009 |
20090074469 | DUAL CHANNEL APPARATUS FOR TRANSPORTING POWDER IN AN ELECTROSTATOGRAPHIC PRINTER - An apparatus and method for distributed mixing and transport of toner and powders in an electrostatographic printer containing at least powder and magnetic carrier. The apparatus includes a powder conveying apparatus for transporting powder in a developer station including a development station housing having two or more auger assemblies, each auger assembly including two or more screw augers supported in a channel profile. The two or more screw augers having multiple intermeshed screw blades and controlled by a conveyance controller. The conveyance controller is in communication with the powder the one or more augers, such that each auger preferentially mixes and transports in a first or second direction as the powder conveying device conveys the powder in the developer sump of a print engine. | 03-19-2009 |
20090190961 | ELECTROGRAPHIC DISTRIBUTED REPLENISHMENT APPARATUS AND METHOD - A developer station and related method for distributed replenishment of toner as well as powder coatings and related materials. The developer station is divided into a first space adjacent or within a second space, the first space located adjacent a toner supply and the second space including a developer sump. The first space includes a toner-conveying device located in the first space, the toner-conveying device having a tapered body with a first end and a second end. A conveyance housing is located adjacent to and disposed such that the toner conveying device conveys the toner toward the developer sump as it travels from the first end of the toner conveying device to the second end of the toner conveying device, the housing having slots or openings so that the toner is deposited in the developer sump along the length of the conveying device. | 07-30-2009 |
20100027035 | DYNAMIC ADJUSTABLE CUSTOM COLOR PRINTER AND CUSTOM COLOR IMAGES - An electrographic printer and related method for providing a custom color including printing custom color on a receiver using a multicolor printer including at least one color module capable of printing at least one color image separation of a first color toner on an imaging member by collecting a first color toner from an imaging member, mixing the first color toner with one or more second color toners in a custom color module to produce a blended custom color toner comprising a mixture of at least the first color toner and a second color toner to produce a custom color image separation. Then printing the custom color image separation by transferring the image to a receiver and fusing the image on the receiver. | 02-04-2010 |
20100247162 | DEVELOPER STATION FOR AN ELECTROGRAPHIC PRINTER HAVING REDUCED DEVELOPER AGITATION - A developer station and method for an eletrographic printer is provided that reduces developer agitation. The developer station includes a sump of magnetic developer, and a magnetic brush roller mounted above said sump and having a rotatable magnetic core surrounded by a substantially cylindrical toning shell rotatably mounted with respect to the core. The toning shell defines a nip at its closest point to the photoconductor element. A tangent line tangent to the cylindrical toning shell at the nip is oriented substantially vertically, and the magnetic developer is applied to the toning shell at an angular distance of no more than about 120° from said nip. The toning shell may be eccentrically mounted with respect to the magnetic core and is substantially closest to the rotatable magnetic core within about +30° and −30° from said nip. Such a configuration advantageously reduces the residence time of the developer on the toning shell. | 09-30-2010 |
20110026976 | ELECTROGRAPHIC IMAGE DEVELOPING APPARATUS AND PROCESS - A method for forming an electrographic image includes providing an imaging member having an electrostatic image and a toning shell adjacent to the imaging member to take into account the slippage as a result of toner particles that are approximately spherical. | 02-03-2011 |
