    摘要: Exemplary embodiments provide a roll member that includes one or more controllable cells and methods for making and using the roll member to control an image (or toner) state thereon. The controllable cells can be disposed on a roll substrate and configured in a manner that each controllable cell can be addressed individually and/or as groups. Each controllable cell can be addressable to provide a surface vibration to release toner particles adhered/attracted thereto and can also be capable of sensing the toner state of the roll member and thus to control the image or toner state. In an exemplary embodiment, the disclosed roll member can be used as a donor roll for a development system of an electrophotographic printing machine to create controlled and desired toner powder cloud for high quality image development.

    摘要: Exemplary embodiments provide a roll member that includes one or more linear arrays of actuator cells and methods for making and using the roll member. In one embodiment, each linear array of the roll member can be controllably actuated as a group by, e.g., an oscillating voltage, to release toner particles adhered thereto and to form a uniform toner cloud in the development area between the roll member and an image receiving member. The controllable actuation can also aid in the unloading process of the residual toner particles from the roll member. In various embodiments, the uniform toner cloud and/or the controllable unloading process can enable a non-interactive development system for image-on-image full-color printing.

    摘要: For an automatic image diagnosis, toned images or residual toner existing on the photoconductive surface of a photoreceptor may be scanned with light energy provided by the raster scanning system. The light energy, which may be reflected from the photoreceptor surface, may be disturbed due to scattering/absorption in toned or damaged surface regions. The light energy may be directed to image sensors to obtain a spatial image map of the photoreceptor surface in conjunction with pixel clock information present for the raster scanning system. The evaluation may be made based on the spatial image map. Diagnostic and maintenance may then be applied to correct the defect and/or adjust a tone level for a latent image formed on the photoreceptor surface.

    摘要: Aspects of the disclosure provide a printing method that can utilize a lightly pigmented toner along with a darkly pigmented toner to improve the image quality. The method can include receiving a dataset corresponding to a printing of a printing system using a darkly pigmented toner. The printing system may have an undesirable optical density printing range for the darkly pigmented toner. Further, the method can include converting the dataset to a first dataset corresponding to a first printing of the printing system using the darkly pigmented toner, and a second dataset corresponding to a second printing of the printing system using a lightly pigmented toner. The first dataset can avoid the undesirable optical density printing range for the darkly pigmented toner, and a combination of the first printing and the second printing providing a substantially same printed optical density corresponding to the received dataset.

    摘要: A xerographic system and method use a tri-level development process in which at least one xerographic imaging unit includes a photoreceptor and a pair of developer units. A first developer unit includes a full strength toner of a given color and a second developer unit includes a reduced strength toner of the same or substantially the same color. By use of the tri-level process, excellent color-to-color registration can be achieved for each processed color separation. Moreover, by use of two strengths of the same colorant, a tighter control of the tone reproduction curve can be achieved. Additional xerographic imaging units can include a developer unit that provides spot color, custom color or specialty color capabilities. Additional benefits and gamut expansion can be achieved through use of a tandem architecture. A preferred implementation uses a four drum, eight color tandem architecture with full strength and reduced strength toners formulations of Cyan, Magenta, Yellow, and Black (CYMK) colorant.

    摘要: Ferroelectric polymer films are applied in a charge transfer imaging process to generate latent electrostatic images on a dielectric receiver media. The dielectric receiver media may be the final imaging substrate which is then xerographically toned and fixed, e.g., Versatec dielectric paper, or an intermediate surface from which a toned image is transferred to plain paper. Charges may be generated applying either the piezoelectric or the pyroelectric effect exhibited by ferroelectric films.
