摘要:
An apparatus for developing a latent image recorded on an imaging surface with a custom color toner, including a developer housing for developing a portion of the latent image with the toner of custom color. The developer housing includes a donor member for transporting toner of the custom color to a development zone to develop the latent image. A replaceable reservoir unit is provided for mixing and supplying the custom color toner to the donor member. An array of toner dispensers is provided for supplying various primary color toners, as required, to achieve the custom color, and additional reservoirs having various colored toners therein to allow for faster convergence to a given point in the color space.
摘要:
A method for producing a toner of a custom color in a developer unit including a housing defining a reservoir for storing a supply of toner, a donor member for transporting toner to an imaging surface; including: identifying custom color requested; determining color of toner in the reservoir; detoning toner on the donor member if the color of toner in the reservoir is beyond a predefined value in color space from the custom color requested; calculating and dispensing primaries toner colors to be added to the reservoir to obtained the custom color requested; mixing the primary toner colors dispensed in the reservoir; and evaluating and comparing the color components of the toner being mixed to the custom color requested.
摘要:
An electrostatic printer having a cleaning blade for removing residual particles from the surface of a photoconductive substrate. A mechanism automatically retracts the cleaning blade away from the substrate to avoid scrapping the cleaning blade against a seam on the substrate.
摘要:
An apparatus and method for stopping rotation and retracting a cleaning brush away from contact regions to avoid the occurrence of flat spots or voids in the cleaning brush and prevent toner emissions from the cleaning brush as it is retracted. The cleaning brush is rotated about a pivot point to move the cleaning brush away from contact with the photoreceptor and the detoning roll. The pivot point is positioned so that the variation in interference to the detoning roll is minimized for variations in the interference and location of the brush against the photoreceptor. Each cleaning brush has a housing that moves in conjunction with the movement of the cleaning brush in order to avoid contact between the housing and the cleaning brush. This cleaning apparatus also enables development of multi-layer color images.
摘要:
A cleaner brush in which air flow passes through the first node of the standing wave of brush fibers to facilitate removal of particles therefrom. A flexible seal maximizes the air flow through the brush fibers.
摘要:
A method and apparatus for adjusting the bias of a cleaner used in a printer or digital copier such that the cleaner bias is optimized for the dominant color entering the cleaner.
摘要:
A cleaning method and apparatus that provides lubrication to a secondary detoning roll in a cleaner brush system, thus reducing cleaning failures. The toner particles removed from the first detoning roll are transported to the second detoning roll. This allows lubrication of the second detoning roll and reduces the wear problem of the second detoning roll due to lack of lubrication.
摘要:
A cleaning brush electrically biased with an alternating current removes discharged particles from an imaging surface. The particles on the imaging surface are discharged by a corona generating device. A second cleaning device including an insulative brush, a conductive brush or a blade, located upstream of the first mentioned brush, in the direction of movement of the imaging surface, further removes redeposited particles therefrom.
摘要:
A multi-mode, long life monochrome printing system that includes (a) a media supply assembly having a media path (b) a moveable intermediate transfer member for receiving images from image output terminal assemblies and for transferring the images to media on the media path; and (c) a plural number of monochrome image output terminal (IOT) assemblies adjacent the moveable intermediate transfer member, each monochrome image output terminal (IOT) assembly being selectably moveable into and out of image transfer relationship with the moveable intermediate transfer member, and each monochrome image output terminal (IOT) assembly having a development unit including developer material having essentially a same color.
摘要:
An apparatus and method is disclosed for increasing brush life and reducing emissions by removing accumulated toner using detoning cycles. A further embodiment of the disclosure is a method for periodic brush-reversing detoning cycle occurring during a standby condition.
