摘要： A defect analysis system for a xerographic print engine includes a residual mass sensor that senses the two-dimensional signature structure of residual mass remaining on a photoconductive or other substrate surface after image transfer. Preferably, the sensor is a full width array that spans substantially an entire width of the photoconductive surface. This information is then processed and analyzed to determine a specific type of transfer defect present. This may include the quantified level of defect for each detected type. The defect analysis system may also include a closed-loop control system that can adjust various xerographic process parameters using feedback based on the identification and optionally magnitude of each specific defect type. The identified print quality defect, such as mottle, streaks, point deletions, graininess, etc. can then be used to determine a customized corrective control action to be taken by the feedback control of the xerographic print engine to remedy or compensate for the defect(s).

摘要： Disclosed is a method and apparatus for sensing residual toner mass after transfer of a xerographic image, to facilitate the identification and characterization of different types of transfer defects. The technique employed utilizes a nominal residual mass signature, measured at the start of a job, in conjunction with subsequent residual mass signature, where the calculated difference between the nominal and subsequent signatures is used to indicate transfer defects and changes in transfer efficiency.

摘要： A xerographic marking engine adjusts a charging actuator, such as an AC peak-to-peak voltage or an AC peak-to-peak AC current, based upon toner patch density measurements made using, e.g., a toner patch density sensor. The sensor is used to detect a knee in a toner mass density curve obtained by sweeping an AC peak-to-peak voltage or an AC peak-to-peak current. Once the knee is located, an AC charging actuator peak-to-peak voltage or AC peak-to-peak current is determined that reduces the amount of positive charge that is deposited onto the surface of the photoconductor, thereby extending its life while maintaining acceptable print quality. The described approach may improve photoconductor life without significantly increasing production costs or complexity.

摘要： The life of the photoconductor in an image forming apparatus is typically limited by the eventual occurrence of some form of print quality defect related to the photoconductor. One of the typical failure mechanisms is the slow wearing away of the surface layer of the photoconductor. Photoconductor run life is improved by operating a charging station in a low wear mode during certain circumstances, including: during printing of a low stress page as detected based on the image data; during at least one of cycle up and cycle down operations to control charging of the at least one photoconductor over at least one print zone for at least one cycle of rotation of the at least one photoconductor; during printing of at least one test patch in a process control cycle; and upon determination from the image data that at least one photoconductor will not contribute to the printing during a next print cycle.

摘要： A method creates a printing image charge on a photoreceptor printing region of a photoreceptor within a printing apparatus and, simultaneously with the creating of the printing image charge, charges source patches on the photoreceptor outside the photoreceptor printing region. The method then transfers developer material from a donor roll to the photoreceptor. The source patches cause developer material to be removed from areas of the donor roll outside a donor roll printing region to create developer material-depleted regions. The method then reloads the donor roll with developer material using a magnetic brush and evaluates a reload function of the donor roll by characteristics of developer material on target patches with developer material in areas of the non-printing region of the photoreceptor adjacent the target patches. The method then alters the printing image charge to maintain the reload function within a predetermined range.

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： Methods and systems print a multi-color test pattern using a printing device to create a printed test pattern when the printing device is producing a printing defect. The methods and systems scan the printed test pattern to produce a scanned image and decompose the scanned image into color blocks using the computerized device. The methods and systems create intensity profiles of the color blocks using the computerized device and compare at least two of the intensity profiles of different colors to determine whether the intensity profiles indicate correlated printing defects using the computerized device. The methods and systems indicate, through the computerized device, whether a potential defect within a common printing element of the printing device or is located within one or more of the color printing elements of the printing device, depending upon whether the intensity profiles have correlated printing defects.

摘要： A method and device detect printing defects on prints produced by an electrostatic printing device and, in response, place the electrostatic printing device into a diagnostic mode. While in the diagnostic mode, the method and device charges an image bearing surface of the electrostatic printing device to a uniform potential charge and disables all light emitting devices of the electrostatic printing device that could alter the uniform potential charge. Next, this method and device transfer marking material to the image bearing surface to create a test image and print at least one test patch by transferring the test image from the image bearing surface to a sheet of media. This method and device evaluate whether the test patch includes the printing defects and identify whether said light emitting devices of the electrostatic printing device is defective, based on whether said test patch includes printing defects.
