Abstract: This invention provides supplying a model that will together with software and a controller, separately selectively cycle up (activate) or cycle down (inactivate) color stations in accordance with their need for a particular imaging run. The cycled down stations are not activated for the imaging run thereby preserving the quality of the developer and toner in that inactivated color station or housing. The model will vary, depending on the machine or desired images. Each model can later be used for machines of the same family.

Abstract: A method for repositioning a mark on a belt after an image on paper registration process, which includes printing a test pattern, measuring at least one test pattern parameter, detecting a mark on a belt and detecting at least one imaging error associated therewith, using the at least one test pattern parameter and the at least one imaging error to determine the lateral distance required to shift a particular image to a desired location on the belt and shifting the image to the desired location.

Abstract: A method for preserving image squareness and image on image registration in a system having a plurality of imaging stations, each imaging station having an ROS. The method includes adjusting the target skew of a reference ROS within one of the plurality of imaging stations by the angular difference between the actual reference ROS position and the target position for the reference ROS and adjusting the target skew of the reference ROS by the skew of the reference ROS relative to the desired skew for image squareness.

Abstract: An image processing control system which employs a patch schedule processor that schedules the writing of patches to the photoreceptor belt on demand in response to adjustments generated by prior cycles of image process control.

Abstract: A printing system for producing prints, with each print including an image represented by image data, is provided. The printing system includes a memory for storing and buffering the image data of a selected print and an image output terminal, communicating with the memory, for printing the image of the selected print on a substrate. The printing system further includes marking software, operatively associated with the image output terminal, for determining a value for the maximum amount of memory to be used in printing selected ones of the prints, and a resource manager, communicating with the marking software and the memory, for managing the memory. In practice, the resource manager receives the value from the marking software and the substrate is fed to the image output terminal when the resource manager determines that the value corresponds with a selected amount of available memory space and that an additional predetermined condition is satisfied.

Abstract: In accordance with the present invention there is provided a method for scheduling transfers in a printing machine of the type having a scheduler communicating with both a first disk and a second disk, the first and second disks having a combined bandwidth. The method for scheduling comprises the following steps: First, a first transfer to be performed on a first location of the first disk during a first time interval and a second transfer to be performed on a second location of the first disk during a second time interval are both scheduled, with the scheduler, so that a first time gap interval exists between the first time interval and the second time interval.

Abstract: An electronic printing system prevents printing failures and interruptions associated with the inability of an image generation subsystem to generate a page image in digital form in real-time by reviewing the page contents prior to submission to the image generation subsystem. The quantity, size, geometry and location of objects on a page are analyzed to generate an internal intermediate description of the page. A determination is made if sufficient resources exist to perform real-time imaging. If real-time imaging cannot be performed, the page will be automatically simplified before the job containing the page is submitted for printing.

Abstract: In plant for the production of alkylated resins from an alcohol of boiling point greater than 100.degree. C. at atmospheric pressure, comprising an alkylation reactor, a distillation column, a condenser, and a separator, structure is provided to ensure that contact between descending alcohol-rich liquid phase and the vapor stream of alcohol and water ascending from the reactor is confined essentially to the walls of the column.
