摘要： Fusers for fusing toner on media, printing apparatuses, and methods of fusing toner on media in printing apparatuses are disclosed. An exemplary embodiment of the fusers comprises a fuser roll comprising a fusing imaging surface; at least one heating element for heating the fuser roll; a pressure roll including an outer surface, the outer surface and the fusing imaging surface defining a nip; a temperature sensor for sensing a temperature on the fusing imaging surface; a time delay calculator connected to the temperature sensor; a feedback controller connected to the temperature sensor and the heating element, the feedback controller receives a signal from the temperature sensor indicating the temperature on the fusing imaging surface and controls the heating element based on the temperature; and an open-loop controller connected to the heating element and the time delay calculator. The open-loop controller receives a time delay signal from the time delay calculator and bypasses the feedback controller to control the heating element to increase the temperature of the fusing imaging surface starting at about a time, t−Δt (where Δt is a time delay), which is before a medium arrives at the nip, and continuing until about a time, t, at which the medium arrives at the nip and is contacted by the fusing imaging surface. The feedback controller resumes control of the heating element at about the time t.

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.

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 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).
