摘要： A system suited to scheduling print jobs for a printing system includes a first processing component which identifies preliminary attributes of print jobs to be printed on sheets. A job scheduler receives the preliminary attributes and assigns each of the print jobs to one of a plurality of job queues in time order for printing. Print jobs spanning the same time are scheduled for printing contemporaneously. In one mode of operation, the assignment of the print jobs to the job queues is based on their preliminary attributes and on the application of at least one constraint which affects contemporaneous printing of at least two of the plurality of print jobs. A second processing component identifies detailed attributes of the print jobs. A sheet scheduler receives information on the assignments of the print jobs and their detailed attributes and forms an itinerary for each sheet to be printed.

摘要： The exemplary embodiments are directed to a control system and method of predicting how a machine will respond to occasional or periodic maintenance or service, and adjusting the machine accordingly to account for the change in machine behavior due to the maintenance or service action. More specifically, in a machine under closed-loop control subject to occasional maintenance or service, the maintenance or service results in transient in machine performance. To mitigate transients in machine performance due to maintenance or service, a prediction of the maintenance or service effect is fed forward the existing control system just prior to the occurrence of maintenance or service in order to compensate for the maintenance or service effect. This prediction is continually updated and refined using subsequent measurements of the effect of maintenance or service on machine performance.

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： A system and method for adjusting the registration of an image applied to recording media in a printer. The timing of the ejection of ink from an inkjet printhead of the printer is adjusted to maintain proper registration of a first side image to a second side image for duplex printing and y registration within a second side image printing from a first color print unit, such as magenta, to a last print unit, such as black. The location of a leading edge of the first side image deposited on a continuous web of recording media is identified and the timing of ink ejection from printhead nozzles is adjusted to align the second side image to the first side image. Adjustment of the timing of ink ejection reduces or eliminates observable registration errors.

摘要： A method for adjusting the tension of a continuous web of recording media in a printing system. The method includes identifying a tension in the continuous web and adjusting the tension in response to the amount of ink being deposited on the recording media. An offset tension value is determined, stored in memory, and used by a controller to adjust the velocity or tension of the continuous web moving through the printing system to improve the printing of images.

摘要： A method enables linear web velocities generated with reference to angular velocity signals generated by encoders at different rollers in a double reflex printing registration system to be equalized. The method includes identifying a low frequency component of a first linear velocity of a moving web, identifying a high frequency component of a second linear velocity of the moving web, and computing a linear velocity for the moving web at a roller in a print zone with reference to the identified high frequency component of the second linear velocity and the identified low frequency component of the first linear velocity.
