Patent number: 8049935Abstract: An optical scanning device is provided which comprises a laser array which emits laser beams including a number of beams (1, 2, . . . , n) writing a swath of rasters having a laser scanning section which, when an interlaced scanning period i, is set to a natural number between beams which are adjacent in a sub-scanning direction, scans the laser beams emitted from the laser array with the interlaced scanning period i. The laser scanning section can scan the laser beams such that the beam number n and the interlaced scanning period i are relatively prime natural numbers, and n>i. In a first scan, data for raster lines (1, 2, . . . , n) can be selectively associated with a respective first exposure. At a second scan, data for raster lines (i+1, i+2, . . . , n) can be selectively associated with a respective second exposure and data for raster lines (n+1, n+2, . . . , n+i) can be selectively associated with a respective first exposure. The first respective exposure for raster lines (i+1, i+2, . . .Type: GrantFiled: January 17, 2011Date of Patent: November 1, 2011Assignee: Xerox Corp.Inventors: Anthony Ang, Robert Paul Loce, Beilei Xu, Robert Kleckner

Patent number: 6418289Abstract: An apparatus is provided for drying a liquid image carried on a surface of a medium moving along a predetermined path from an upstream location towards a downstream location. The apparatus includes an air moving device, such as a blower, that moves air. A plenum has an intake that receives air and an outlet permitting the air to exit the plenum. A channel structure communicates with the outlet of the plenum and is disposed generally adjacent to a surface of the medium carrying the image. The channel structure includes an upstream channel portion and a downstream channel portion such that air exiting the outlet of the plenum is diverted to flow towards the upstream location in the upstream channel portion and towards the downstream location in the downstream channel portion. A heater is associated with the medium to heat at least a portion of the medium and thus the image. A method of drying a liquid image on a surface of a medium is also provided.Type: GrantFiled: November 29, 2000Date of Patent: July 9, 2002Assignee: Xerox CorporationInventors: Robert Kleckner, Gerald A. Domoto, F. James Wang

Patent number: 5173797Abstract: An optical scanner has grease bearings between the rotor and the housing. The grease bearings are grooved which tends to pump the grease back into the bearing cups when the optical scanner is operating. The thixotropic property of the grease prevents its escape from the bearing cups when the optical scanner is not operating. The grease bearings can be frusto-conical or spherical in shape with complementary shaped bearing cups. The bearing cups, rather than the bearings, may be grooved. The bearing cups may also be stepped to provide a pumping region and a reservoir region for the grease. Pressure means within the scanner housing may force the bearing cups onto the grease bearing.Type: GrantFiled: May 8, 1990Date of Patent: December 22, 1992Assignee: Xerox CorporationInventors: Stanley Zedekar, Kevin E. Jones, Vinod Mirchandani, Vittorio Castelli, Robert Kleckner
