Filed:

Dec 7, 2006
Appl. No.:

11/635741
Inventors:

Rajinderjeet S. Minhas - Churchville NY, US
Assignee:

Xerox Corporation - Norwalk CT
International Classification:

G06K 15/00
G06K 1/00
G06F 15/00
H04N 1/407
H04N 1/40
US Classification:

358 118, 358 19, 358 326, 358 329, 703 7, 399 81, 399138
Abstract:

A system for visualizing a print job includes a print job simulator which applies a print job model to print job image data to generate an image which simulates a rendered image of the print job if the print job were to be printed on a specific marking device. The system also includes a display in communication with the print job simulator for displaying the simulation image. The modified image data displayed on the display enables a customer to see a defect in the print job which would appear if the print job were to be rendered on the specific marking device. The print job model may be derived, at least in part, from information derived from the marking device, such as information derived from image data acquired by scanning a test image which has been rendered by the marking device.

Filed:

Jun 19, 2009
Appl. No.:

12/487803
Inventors:

Rajinderjeet Singh Minhas - Churchville NY, US
Vishal Monga - Torrance CA, US
Wencheng Wu - Webster NY, US
Divyanshu Vats - Minneapolis MN, US
Assignee:

Xerox Corporation - Norwalk CT
International Classification:

G21C 17/00
G06F 11/30
US Classification:

702185, 702181, 702183, 702 81, 702179, 702184, 700174, 324500, 355 18, 355 78, 358 326
Abstract:

A method and system for automatically determining an optimal re-training interval for a fault diagnoser based on online monitoring of the performance of a classifier are disclosed. The classifier generates a soft measure of membership in association with a class based on a training data. The output of the classifier can be utilized to assign a label to new data and then the members associated with each class can be clustered into one or more core members and potential outliers. A statistical measure can be utilized to determine if the distribution of the outliers is sufficiently different than the core members after enough outliers have been accumulated. If the outliers are different with respect to the core members, then the diagnoser can be re-trained; otherwise, the output of the classifier can be fed to the fault diagnoser.

Assignee:

Palo Alto Research Center Incorporated - Palo Alto CA
International Classification:

G06F 11/00
US Classification:

714 46
Abstract:

A printing system includes a plurality of print media processing modules which transfer print media therebetween during printing and a fault management agent associated with each of the modules for acquiring fault-related data from the respective processing module. A fault management system is in communication with the fault management agents and receives fault-related data from the fault management agents. The fault management system processes the fault related data to identify faults in the system, such as when a first of the processing modules is a cause of fault-related data acquired in a second of the processing modules. When a fault is identified, a reconfiguration agent may reconfigure the printing system to mitigate an impact of at least one of the identified faults.

Abstract:

Systems and methods for implementing use of customer documents in maintaining image quality or image quality consistency of printing devices are provided. The system may include a marking engine constructed to print images on an image bearing surface of the print device; one or more color measuring devices for measured toner images formed on the image bearing surface corresponding to the one or more relevant pages, and an image analyzer configured to generate reference images and to compare measured image data with the reference images. The image analyzer may also be configured to analyze input image data for a document and to identify one or more relevant pages of the document that may provide information regarding the state of the printing system to generated reference image data. Comparisons between the color separations of the reference image data and measured image data images may be realized for determining defects.
