Patent number: 7922288Abstract: A printing system includes a first image applying component configured for applying one or more primary colorants to print media for rendering an image. A second image applying component is configured for applying a second colorant, such as black colorant, to print media for rendering an image. A first pathway conveys print media between the first image applying component and the second image applying component. A second pathway bypasses the first image applying component for conveying print media which is printed by the second image applying component. Where an image is to be rendered with the primary colorants and optionally also black, the print media is directed on the first pathway to both the first and second image applying components. Where an image is to be rendered only with black colorant, the print media may be directed to the second image applying component via the bypass pathway. In this way, during black printing, the first image applying component can be placed in a standby mode.Type: GrantFiled: November 30, 2005Date of Patent: April 12, 2011Assignee: Xerox CorporationInventor: David A. Mueller
