Patent number: 7894111Abstract: The presently described embodiments generate a single job that tests multiple image path parameter combinations. The user first selects the part of the document that will be used for the test run. The system then determines all the available image path control parameters and settings that are compatible with the selected document parts. The system builds a menu, and the user chooses the image path control parameters and settings combinations that are to be tested. The user then sends the job to the printer which prints the selected parts of the documents using each of the selected image path parameter combinations. Appropriate labels are included in the printed output so the user can easily identify the combination that delivers the most satisfactory results.Type: GrantFiled: December 18, 2006Date of Patent: February 22, 2011Assignee: Xerox CorporationInventors: Geoffrey J.
