Patent number: 7677717Abstract: A maintenance system and method for maintaining an imaging member of an imaging device includes a pre-cleaning device to clean the imaging member; an applicator to apply release agent to the imaging member; a metering device to meter release agent on the imaging member; a reservoir to remotely store release agent; and a pump to supply the applicator with release agent from the reservoir. The saturation level of the applicator is monitored and maintained within a predetermined range. The applicator, pre-cleaning device and metering device may be independently actuated to engage the imaging member. Release agent collected by the pre-cleaning device and/or metering device may be recycled. Debris collected by the pre-cleaning device and/or metering device may be stored and/or removed.Type: GrantFiled: December 23, 2005Date of Patent: March 16, 2010Assignee: Xerox CorporationInventors: Abu S. Islam, Michael C. Gordon, Joseph B. Gault, Alexander J. Fioravanti, Kelly Anne Kessler, Larry Eugene Hindman, Bruce Karl Baur, Ernest I. Esplin, Scott J. Phillips, Roger G. Leighton

Patent number: 7677716Abstract: Ejected liquid forms a latent image on a charged transfer surface. In some invention aspects electrostatic charge is first applied to the surface; inkjet devices eject the image-forming liquid; voltage is established between the devices and surface; another, separate substance associated with the latent image actuates it. In other aspects hydrophobic or hydrophilic material in the surface stabilizes the image on it; electrostatic apparatus, associated with the surface, cooperates with the stabilizing material, further controlling image-droplet position and size. In other aspects a desired image forms on a final printing medium, based on an input electronic image-data array; the liquid ejection is onto an intermediate transfer surface, based on detailed incremental control by the data, forming a latent image representing the desired image.Type: GrantFiled: January 26, 2005Date of Patent: March 16, 2010Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ramon Vega, Jordi Ferran, Eduardo Martin, Emilio Angulo, Jorge Castano, Pedro Luis Las Heras

Patent number: 7673981Abstract: An image formation apparatus with a plurality of laser diodes that form color-component images, which correspond to a plurality of color components, onto a plurality of corresponding photosensitive drums respectively, and a transfer belt onto which the color-component images that are formed on the respective photosensitive drums are transferred. The image formation apparatus adjusts the image formation timing based on the positions of the color-component images that are transferred to the transfer belt; and when adjusting the image formation timing, the respective laser diodes form color-component images at formation intervals that correspond to an integral multiple of the period of a periodic noise.Type: GrantFiled: March 8, 2006Date of Patent: March 9, 2010Assignee: Sharp Kabushiki KaishaInventor: Kengo Matsuyama

Publication number: 20100053292Abstract: A application apparatus for metering release agent onto an image forming device moving surface, such as a Solid Ink Jet drum. The application apparatus includes a blade positioning mechanism with first and second links each having three pivot connections for pivotally connecting first and second blades together in mutually exclusive cooperative movement alternating between a common working position at a first location and respective suspended positions. The application apparatus can include a doctor blade arrangement in which the blades are disposed in a doctor blade orientation in the working position. The application apparatus can include a wiper blade arrangement in which the blades are disposed in a wiper blade orientation in the working position. The first and second blades form similar blade holder angles, blade deflection angles and Working Angles when occupying the working position.Type: ApplicationFiled: August 29, 2008Publication date: March 4, 2010Applicant: XEROX CORPORATIONInventors: Bruce E.

SYSTEM AND METHOD OF ADJUSTING BLADE LOADS FOR BLADES ENGAGING IMAGE FORMING MACHINE MOVING SURFACES
Publication number: 20100053293Abstract: Systems and methods of providing controlled blade engagement with an image forming machine moving surface are provided for metering a release agent onto the surface, cleaning the surface, or both. A blade engagement apparatus is provided having a controller controlling an actuator connected to a blade positioning mechanism for providing controlled engagement of the blade with the moving surface. The minimum blade load applied by the blade to the moving surface needed to prevent defects is determined and maintained for increasing the useful life of the blade. Control systems and methods utilizing single and separately operable dual blade positioning mechanisms are provided.Type: ApplicationFiled: August 29, 2008Publication date: March 4, 2010Applicant: Xerox CorporationInventors: Bruce E.

Patent number: 7661809Abstract: A method and apparatus for forming an image which can form a high-quality image on a great variety of print media regardless of the surface roughness or ink absorptivity of the print medium, without sacrificing the high degree of freedom of the ink jet printing system are provided. An ink jet printing section ejects ink to an intermediate transfer body to form an ink image on the intermediate transfer body. Before the ink image thus obtained is transferred to a print medium, an ink transfer adjuvant is applied to the print medium. Then, the ink image formed on the intermediate transfer body is transferred to the print medium to which the ink transfer adjuvant has been applied.Type: GrantFiled: November 15, 2004Date of Patent: February 16, 2010Assignee: Canon Kabushiki KaishaInventors: Hiroshi Taniuchi, Akihiro Mouri
