    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 closed-loop toner concentration adjustment system extends xerographic process control performance with a system and method including a first controller to adjust toner concentration (TC) in a developer of the imaging device to alter a DMA level of the imaging device, the TC being adjusted based on a TC target value; a second controller to adjust an electrostatic development field to alter the DMA level; and an adjustment logic device to adjust the TC target value based on adjustments made to the electrostatic development field. The first controller outputs a dispense amount to the developer based on a difference between a measurement of the actual TC and the TC target value, thereby adjusting the TC based on the dispense amount to the developer. The second controller adjusts the electrostatic development field based on a difference between a measurement of the actual DMA level and a DMA target value. The adjustment logic monitors the adjustments made to the electrostatic development field to determine a trend, and adjusts the TC target value based on the trend.

    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 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.

    摘要: A printing system includes a plurality of printers, at least a first and a second of the plurality of printers printing in a first print modality. A scheduling system schedules printing of a set of pages by the plurality of printers. The set of pages, when assembled, may include pages where a high level of consistency is desired, such as facing pages or pages which are otherwise to be placed in close relationship. The scheduling system includes at least two scheduling modes, a first mode in which a consistency constraint is applied to the set of pages, and a second mode, different from the first mode, in which the consistency constraint is not applied. The printing system is configured for printing the set of pages in accordance with the first mode and in accordance with the second mode.
