20080239341 | SYSTEM AND METHOD FOR CONTROLLING CONSISTENT COLOR QUALITY - A system and method control a consistent color quality of overlay colors and single separations of color. The method determines a first error for a first separation of a first color, wherein the first error has a first sign. The method identifies a second error for a second separation of a second color, wherein the second color is a different color than the first color, wherein the second error is based on an actual density value for toner particles printed transferred from the second separation, wherein the second error has a second sign. The method compares the first sign of the first error and the second sign of the second error. The method converges the actual density value of the second separation to a target position when the first sign is a different sign than the second sign. | 10-02-2008 |
20090148183 | METHOD AND APPARATUS FOR SHIFTING IMAGE FORMING APPARATUS PHOTORECEPTOR TO REDUCE GHOST FORMATION - A method and apparatus for shifting a photoreceptor in a cross-process direction to reduce the formation of a paper edge ghost on the photoreceptor. The shifting can occur continuously or in steps. | 06-11-2009 |
20090162083 | DYNAMIC ESV (SENSOR) POSITIONER FOR MULTI-COLOR CONFIGURATION - A method and system for providing dynamic sensor positioning in a color image forming device. Movably mounted sensors are provided in color printers and color reproduction to a plurality of color control patches, resulting in reduced production and mounted ESV that can be positioned substantially adjacent to a plurality of color control patches, thereby, allowing for a single ESV in a multi-color image forming device. | 06-25-2009 |
20090279115 | OBTAINING PRINT SYSTEM SETTINGS FOR SELECTED PRINT MEDIA ATTRIBUTES IN A NETWORKED PRINT JOB ENVIRONMENT - What is disclosed is a novel system and method for automatically retrieving and configuring the print device to a set of device specific system settings tailored for user selected media attributes. In one embodiment, an operator selects media attributes desired for a particular print job on a print device which then automatically queries a database over a network for a set of device specific system settings tailored to the selected media attributes. The database system determines the existence of at least one record stored in the database and provides that matching record data back to the print device. The matching record data is received and displayed on a user interface for review by an operator. The operator accepts/modifies the displayed system settings. The print device then automatically configures the device to the accepted device specific system settings. | 11-12-2009 |
20090304408 | MULTI-COLOR PRINTING SYSTEM AND METHOD FOR HIGH TONER PILE HEIGHT PRINTING - Document processing systems and methods are presented in which one or more pages of a print job are segmented into two or more parts, with the first part being transferred and affixed to the printed medium prior to transferring and affixing the second part, in order to facilitate high TMA (pile height) printing while mitigating adverse retransfer, blur, fusing, and hollow character effects. | 12-10-2009 |
20090322849 | USE OF REGISTRATION MARKS AND A LINEAR ARRAY SENSOR FOR IN-SITU RASTER OUTPUT SCANNER SCAN LINE NONLINEARITY DETECTION - A method for detecting, in-situ, a cross-process linearity error in an image printing system that prints on an image bearing surface movable in the process direction is provided. The method includes placing marking material to form of a row of registration marks on the image bearing surface, detecting a position in a cross-process direction of each registration mark in the row using a linear array sensor that extends in the cross-process direction, and determining a correction function with a processor using the positions of the registration marks as detected by the linear array sensor to compensate for an error in the positions in the cross-process direction of the registration marks. The row of registration marks extends in a cross-process direction transverse to the process direction. | 12-31-2009 |
20100196069 | MULTI-COLOR PRINTING SYSTEM AND METHOD FOR HIGH TONER PILE HEIGHT PRINTING - Methods are presented in which one or more pages of a print job are segmented into two or more parts, with the first part being transferred and affixed to the printed medium prior to transferring and affixing the second part, in order to facilitate high TMA (pile height) printing while mitigating adverse retransfer, blur, fusing, and hollow character effects. | 08-05-2010 |
20100310272 | TWO-COLOR IOI DRUM MODULE ENABLING N-COLOR MONOCHROME, HIGHLIGHT, FULL COLOR, PHOTOTONE COLOR AND EXTENDED COLOR ARCHITECTURES - A xerographic marking device includes an intermediate transfer unit, a media transport path and at least one two-color image-on-image (IOI) drum module. Each two-color IOI drum module includes in a process order around a photoreceptor; a) a first charging unit; b) a first exposure unit; c) a first development unit; d) a second charging unit; e) a second exposure unit; and f) a second development unit, wherein the intermediate transfer unit receives a first toned image and a second toned image from the photoreceptor in a single transfer and transfers those toner images to print media to produce a toned image on print media. In various embodiments, specific color pairings are provided. | 12-09-2010 |
20110194131 | AUTOMATED POSITIONING OF PRINTED IMAGES - A method of calibrating a printing system for positioning at least one printed image, the printing system includes a first image bearing surface, the method includes: a) forming a background pattern and at least three fiducials on the first image bearing surface, wherein the background pattern is larger than a first printed image and the at least three fiducials are within an area formed by the first printed image; b) transferring a portion of the first printed image to a second image bearing surface; c) measuring a first residual image on the first image bearing surface, wherein the first residual image is a portion of the background pattern and the at least three fiducials remaining on the first image bearing surface after the step of transferring; and, d) calculating at least one calibration parameter for the printing system based on the measuring of the first residual image. | 08-11-2011 |
