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 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： A printing system includes first and second marking devices for applying images to print media. A first primary fusing device is associated with the first marking device for applying a primary fusing treatment to the images applied to print media by the first marking device. A second primary fusing device is associated with the second marking device for applying a primary fusing treatment to the images applied to print media by the second marking device. At least one secondary fusing device receives printed media from the first and second marking devices.

摘要： The presently described embodiments relate to improving system productivity where maintenance purge routines are required through use of a digital front end (DFE) job scheduler. This approach utilizes knowledge of future jobs to maximize productivity. So, even if a low coverage area job is being processed, and a purge routine is scheduled, the purge routine may be avoided. This is achieved by projecting the system evolution over a future time horizon and determining the schedule of toner purge events (a non productive dead cycle) to minimize a cost function that penalizes the purge event (dead cycling and material loss should be minimized) and the deviation of average toner resident time in the sump from some desired set point of range. In this regard, knowledge that a high coverage area job is downstream and average toner residient time may be advantageously used to effectively perform the purge itself while in productive mode. The system gains knowledge of whether low coverage area jobs or high coverage area jobs are pending by using information stored within the print job file (e.g., a page description language job file). For example, a page description language (PDL) file typically includes information on the area coverage trajectory over time. This will allow a system to generate a predictive model which can constantly recalculate statistics based on knowledge of currently running jobs, new jobs or a change in customer criteria.

摘要： A printing system includes first and second marking engines in series which each include an image applying component for applying an image to print media and a fixing device for at least partially fixing the applied image. One or both marking engines are operable in first and second modes of operation. In the first mode, the fixing device at least partially fixes the image applied by the respective image applying component. In the second mode, the fixing device is used to further fix an image on the print media which has been applied by the image applying component of the other marking engine without an intermediate application of an image to the print media by the second image applying component. A processing component controls the marking engine to operate in a selected one of the first and second modes of operation.
