Patent number: 7791777Abstract: A method and apparatus is disclosed for color balancing page data, from a variety of input sources having non-consistent device color profiles, among a plurality of individually accessible print engines arranged in a system for color printing multiple copies of multiple page documents. Input page data is converted to a common color space, rasterized and routed to a selected print engine. Page data routed to each marking engine is color balanced to the selected marking engine where at least a portion of the color balancing occurs following the rasterizing of the page data.Type: GrantFiled: March 8, 2008Date of Patent: September 7, 2010Assignee: Electronics For Imaging, Inc.Inventors: Michael W. Barry, Jack N. Bartholmae, Francis A. Rowe, Neal E. Tompkins, Peter A. Zuber

Patent number: 7554687Abstract: The toner in the toner cartridge is determined by taking each of the rasterized images output by the RIP and evaluating the pixel levels over the surface thereof. The average value is determined as a percentage of the maximum toner that can be applied to the page. This is then subtracted from a toner value and a remaining toner level determined. Further, all pages of the rasterized document can be evaluated to predetermine the toner level after printing. If this falls below a predetermined minimum, printing is inhibited for that document.Type: GrantFiled: November 23, 2007Date of Patent: June 30, 2009Assignee: Electronics For Imaging, Inc.Inventors: Michael W.

Patent number: 7532347Abstract: Methods and apparatus are described for routing page data of a print job to printers in a multi-engine printing system based on print job parameters associated with the page data. One or more virtual printers are configured, each with a plurality of individual print engines, each having associated printing characteristics. Page data of the print job are rasterized and stored as bit-mapped images in print buffers associated with the multi-engine printing system. The bit-mapped images are distributed to select ones of the print engines based on matching the print job parameters of each bit-mapped image with the printing characteristics of the print engines to be selected.Type: GrantFiled: April 16, 2007Date of Patent: May 12, 2009Assignee: Electronics for Imaging, Inc.Inventors: Michael W.

Patent number: 6707563Abstract: A multiple print engine configuration allows a plurality of workstations (10) to create individual print jobs and then transfer them to a distributing processor (14). The distributing processor (14) is operable to spool the jobs in a print spooler (20) and then perform a software RIP on the print jobs. The RIP process divides the jobs into multiple individual jobs which are stored in the page buffer (24). An image task manager (26) in conjunction with an engine manager (28) are then operable to selectively distribute the pages to multiple print engines (16). They are distributed in such a manner that they are placed in the output bins (40) in the order that the pages were received in the print jobs.Type: GrantFiled: January 18, 2000Date of Patent: March 16, 2004Assignee: T/R SystemsInventors: Michael W.

Patent number: 5745657Abstract: A mapping system is provided for mapping a first contone image and a second bi-level higher resolution image to an output image space for an electrophotographic marking engine, utilized as a printer. A bi-modal hardware device (22) is provided for receiving the information for the two images and then mapping it to the output image space in the marking engine (10). The pixel data associated with the high resolution image is stored in a FIFO (164) and then count values stored in a FIFO (158) associated with the portion of the line in the output image space that is associated with the high resolution image. The pixel data for the portion of the line associated with the low resolution image is stored in a FIFO (182) with a corresponding count value stored in a FIFO (178). A counter is then operable to determine how many pixels of the high resolution image are to be mapped in the output image space.Type: GrantFiled: June 22, 1994Date of Patent: April 28, 1998Assignee: T/R SystemsInventors: Michael W.

Patent number: 5583623Abstract: A buried electrode drum (48) includes a rigid core (10) over which a controlled durometer layer (12) is disposed. On the surface of the controlled durometer layer (12) is disposed a buried electrode layer (14), having electrodes (16) disposed therein along the longitudinal axis of the drum (48). The electrode layer (14) is covered by a controlled resistivity layer (18). The controlled resistivity layer (18) is operable to be contacted on the surface thereof by an electrode (24) to allow a voltage to be transferred to the underlying electrodes (16) and therefrom along the longitudinal axis of the drum (48). Various electrodes can be disposed about the peripheral edge of the drum (48) to allow any pattern to be formed on the surface of the drum (48).Type: GrantFiled: June 6, 1995Date of Patent: December 10, 1996Assignee: T/R SystemsInventors: Jack N.
