    摘要: A control system for use with a development process including at least one magnetic roll with a settable speed is provided. The controller is directly or indirectly responsive to a reload feedback signal, which signal is generated in response to changes in output reload performance of the development process. In the case of direct responsiveness, the controller uses one or more reload feedback signals to facilitate magnetic roll speed setting. In the case of indirect responsiveness, the controller uses a reload sensitivity signal, which reload sensitivity signal varies as a function of input digital image content and output reload performance feedback, to facilitate magnetic roll speed setting.

    摘要: An improved development system for an electrophotographic system includes a reload defect detector for generating a signal corresponding to a potential for reload defect detected in an image to be developed by an electrophotographic system; and a magnetic roll speed selector for selecting a rotational speed for a magnetic roll in a development system of the electrophotographic system, the selected rotational speed corresponding to the generated reload defect potential signal. The speed of the magnetic roll is selected to be a lower speed in response to the potential for reload defect being relatively low. The slower rotation of the magnetic roll prolongs the life of the developer and extends the operational life of the development system before corrective action is needed.

    摘要: A method and apparatus transfer a material from first roller within a container to at least one second roller, and transfer the material from the second roller to at least one third roller. The second roller and the third roller form a loading nip at a location where the second roller is closest to the third roller. The method and apparatus transfer the material from the third roller to at least one recipient device, and measure current flow between the second roller and the third roller using a measurement device. Then, the method alters the relative rotation rate difference between the first roller and the second roller based on the current flow to maintain a predetermined density of the material at the loading nip using a controller.

    摘要: A printing system is provided for color job matching of the output from a plurality of image marking engines. The system includes a first test image printed by a first image marking engine on a media document. The first test image having a data glyph and a plurality of reference patches. The system further includes a second test image printed by a second image marking engine on the media document. The second test image having a data glyph and a plurality of reference patches. The first and second test images are printed on the same side of the media document. A scanner is provided for scanning the media document. The scanned first and second test images provide calibration data for matching color correction tables of the first image marking engine and the second image marking engine, wherein the data glyph and the reference patches of the scanned image data are compared with retrieved color correction tables for generating compensation values based on a difference between the scanned image set-up data and the color correction tables for at least a first subsequent image document on the first image marking engine or the second image marking engine.
