摘要： A corona generating device of the type in which a control grid adjacent a corona generating electrode regulates the charge deposited onto an imaging surface. The control grid defines elongated apertures located in alignment with the electrode, extending along a portion thereof wherein the control grid is adapted to selectively control the charge deposited on the imaging surface area for preventing development of the edge regions thereof.

摘要： An apparatus for developing a latent image recorded on a photoconductive member in an electrophotographic printing machine having a reservoir for storing a supply of developer material and a magnetic rush roll for transporting material from the reservoir to each of two donor rolls. The developer material has carrier granules and toner particles. The donor rolls receive toner particles from the magnetic brush roll and deliver the toner particles to the photoconductive member at spaced locations in the direction of movement of the photoconductive member to develop the latent image recorded thereon.

摘要： An apparatus which develops an electrostatic latent image recorded on a photoconductive member employed in an electrophotographic printing machine having a finite, usable life. The apparatus employs a developer material which ages during the life of the electrophotographic printing machine. A continuous supply of carrier granules is furnished to the developer material. The addition of these carrier granules extends the useful life of the developer material so as to correspond to at least the useful life of the electrophotographic printing machine.

摘要： An apparatus in which an image region recorded on a photoconductive surface is developed with a dry developer material. A transport moves the dry material closely adjacent to the photoconductive surface. The charge induced on the transport by the charge on the photoconductive surface is controlled to electrically bias the transport to a potential intermediate the potential of the image region and non-image region of the photoconductive surface.

摘要： A method of operating a printer produces duplex images in print jobs including ink images to be printed to tabbed, hole-punched, and differently sized media sheets with improved throughput. The method synchronizes a media transport to insert a differently sized media sheet with reference to the type of media sheet, enabling the media sheet to contact a portion of the roller bearing substantially less release agent than the rest of the roller, minimizing release agent transfer to a second side of the media sheet.

摘要： A method for operating an inkjet printer to form images that include both high density and low density segments has been developed. The method includes operating one printhead to eject ink drops with a large size to form high density segments of the image, and operating a second printhead to eject ink drops with a small size to form low density segments of the image. The large ink drops provide high coverage in the high density segments, and the small ink drops provide improved image quality in the low density segments of the image.

摘要： A printing device can be configured with different numbers of ink colors and ink types to print with a different cross-process direction print resolution for each ink color and ink type. The printing device includes a plurality of printhead arrays with each printhead array being configured to eject ink onto an image receiving surface at a first print resolution in a cross-process direction. Each ink supply in a plurality of ink supplies is configured to provide ink to one printhead array in the plurality of printhead arrays, and a controller is configured to operate the printhead arrays at one of at least two combinations of ink colors and ink types. The controller operates the printhead arrays ejecting a same ink color or a same ink type at a second print resolution in the cross-process direction that is different than the first print resolution.
