International Classification:

G03G 1500

US Classification:

399 82, 399 23

Abstract:

A method of controlling paper stock fault recovery in an image reproduction system for producing a print job from electronic data in accordance with job requirements calling for a desired stock having one or more selected stock attributes, the system including an interactive user interface enabling a system user to input operating instructions to the system. A dialog is thereby provided in which the operator may query any stock tray and get a listing of those stock tray attributes which are mismatched with the print job desired stock attributes.

International Classification:

G06K015/00

US Classification:

358504, 358 321, 358 324

Abstract:

A system for compensating for a calibration drift in an image output device includes a user input means for specifying an output medium. An image output device controller converts original image data to final image data used by the image output device. The image output device produces a calibration image, as a function of an output medium, for a plurality of halftone screens capable of being produced by the image output device. A processor communicates with the controller. The processor calculates a plurality of candidate tone reproduction curve sets for the specified output medium. Each of the sets corresponds to one of the plurality of halftone screens. The candidate tone reproduction curve sets are accepted for compensating for a calibration drift in the image output device.

US Classification:

399 82, 399 16, 399 81, 399407

Abstract:

An improvement in a finishing system that eliminates ‘cut and try’ by a user in trying to place staples in copy sheet sets in a desired position includes using input media orientation and the user's Finishing Selection to determine stapling position on output copy sheets.

Appl. No.:

11/676788

Inventors:

Michael A. WIEGAND - Webster NY, US
Richard J. EDDY - Webster NY, US

Assignee:

XEROX CORPORATION - Stamford CT

International Classification:

H04N 1/00

US Classification:

358 118

Abstract:

A method of operating a printing system is described, wherein the system includes a marking device, a controller, and a digital front end. The digital front end manages paper jam recovery of a paint job containing ordered stock, including programming the system to produce a pretermined number of prints of ordered stock, selecting an ordered stock comprising successive sets of sheets with each sheet in each of the sets being unique and the unique sheets in each of the sets arranged in a predetermined order, determining the number of different sheets of stock per group from the number of pages in the job and the predetermined number of prints to be made, and utilizing the digital front end upon occurrence of a paper jam to purge the predetermined number of prints of ordered stock.

Appl. No.:

13/410334

Assignee:

Xerox Corporation - Norwalk CT

International Classification:

B42C 11/02
B42C 11/00

US Classification:

412 4, 412 19

Abstract:

The disclosed book production system and method allow a book block and flexible book cover for that book block to be printed in the same print job immediately prior to binding. Specifically, a user-selection indicates that a book print job contains both the book block and the cover. Raster image processing is performed to produce raster images based on all page descriptions in the print job. The raster images are sorted by size to identify first raster images for the book block pages and to identify at least one second raster image, which is more than twice as large as any of the first raster images, for the cover. The pages for the book block and the cover can be printed on first print media sheets and on a second larger print media sheet, respectively. Then, the cover can be bound to the book block by an in-line bookbinder.

Appl. No.:

8/550320

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G06K 1500

US Classification:

395112

Abstract:

A digital printing system includes a plurality of decomposers which operate simultaneously and independently. Each decomposer outputs page images of decomposed data at essentially random times. The page images from the decomposers are retained in a buffer until requested by a marker which controls the printer hardware. A buffer manager records where in the buffer each page image is stored, and a stream handle is assigned to every set of page images intended to form a multi-page document. When the marker requests a particular set of page images for printing, the marker invokes a stream handle. The buffer manager, receiving the stream handle, retrieves the necessary page images from recorded locations in the buffer.

International Classification:

G06F 1210

US Classification:

711206

Abstract:

In a real-time printing system, in which large blocks of digital data corresponding to page images must be located in a memory via a translation table and accessed from the memory within a very narrow time frame, the memory-management internal program of an operating system is overridden by external instructions which lock the translation table in memory.

Appl. No.:

8/550312

Inventors:

David Plakosh - Rochester NY

Norman E. Wright - Rochester NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G06T 1100

US Classification:

395115

Abstract:

A high-volume digital print service has a plurality of independent and simultaneously-operable decomposers which each output decomposed image data to a common buffer. The decomposed data can be compressed for relatively long-term retention in the buffer, by means of a compression element. All of the decomposers and the compression element are operated by a central CPU facility. A control system, sensitive to the amount of data in the buffer at a given time, apportions CPU cycles among the decomposers and compression element for optimization of the entire print service. The control system can also command printing hardware to skip pitches on an imaging surface therein, in order to reduce demand for decomposed data.
