摘要： An apparatus which develops a latent image, corresponding to an original document, recorded on a moving member. The apparatus includes a first developer unit and a second developer having their characteristics regulated so that the density of the developer material deposited on the latent image by the second developer unit approximates that of the original document over a first density region of the original document. The density of the developer material deposited on the latent image by the second developer unit or both the first developer unit and the second developer unit approximates that of the original document over a second density region.

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 for calibrating in situ a plurality of printheads in an imaging device has been developed. Firing signals operate a plurality of printheads to form ink test patterns on an image receiving member. Reflectance measurements of light reflected from the test patterns and optical density measurements for a portion of the patterns formed by only one printhead in the plurality of printheads are used to adjust the firing signals and enable the printheads to print within a predetermined range about an average reflectance value and a predetermined optical density.

摘要： A method generates a test pattern on an image receiving member that is less perceptible to human observation, but still detectable by an imaging device within a printer. A method implemented in the printer analyzes image data of the dashes in the test pattern that were randomly distributed in the process direction within an area of the image receiving member to identify positions for printheads in the printer and detect missing inkjets in the printheads.

摘要： A system and method is provided for compensating for a faulty ink jet in a target printhead in an ink jet imaging system having a plurality of printheads arranged to span a maximum printing width that includes defining a typical printing width less than the maximum printing width and swapping the target printhead with a printhead situated in the margin outside the typical printing width. The system and method permits swapping the target printhead with a margin printhead that has a faulty ink jet provided that the location of the faulty ink jet in the margin printhead does not coincide or align with a faulty ink jet in printheads adjacent the target printhead.
