Patent number: 7505722Abstract: This is a pre-heater system especially useful in an electrostatic marking apparatus. It is used to heat the toner and paper (media) prior to the paper entering the conventional fuser station. Using this pre-heater increases fusing productivity (ppm), widens media latitude and/or extends fuser member life for a given fuser system. It also dramatically improves uniform heat transfer and paper handling problems encountered in prior art preheat fusing assemblies. The preheater is used together with the conventional fuser stations used today in electrostatic marking systems.Type: GrantFiled: February 8, 2007Date of Patent: March 17, 2009Assignee: Xerox CorporationInventors: Anthony S. Condello, Elias Panides, Augusto E. Barton

Publication number: 20090003896Abstract: An enhanced sheet stripping method and apparatus for stripping toner image carrying copy sheets from a surface of a moving heated fusing member forming a fusing nip. The apparatus includes (a) a moving assembly for moving a cut sheet towards the fusing nip; (b) a sheet curling device positioned upstream of the fusing nip relative to movement of the cut sheet for inducing a desired pre-curl in the cut sheet before the cut sheet enters the fusing nip; and (c) a sheet stripping device positioned downstream of the fusing nip for stripping the cut sheet from contact with the surface of the moving heated fusing member as the cut sheet exits the fusing nip. The method includes inducing a desired curl in the cut sheet before the cut sheet enters the fusing nip and enhanced stripping the cut sheet from contact with the surface of the fuser roll as the cut sheet exits the fusing nip.Type: ApplicationFiled: June 27, 2007Publication date: January 1, 2009Applicant: XEROX CORPORATIONInventors: Gerald A.

Patent number: 6456309Abstract: Color electrophotographic printers having latent image positions synchronized with start-of-scan signals. A laser source projects a laser beam onto a multifaceted rotating polygon that sweeps that beam in a scan line across a moving photoreceptor. A start-of-scan detector produces start-of-scan signals when the laser beam is in position to write a scan line. A belt sensor produces belt signals when indicia on the photoreceptor passes a reference position. A controller receives the belt signals and the start-of-scan and then adjusts the photoreceptors rotational velocity such that the belt signals are an integral multiple of the start-of-scan signals. To reduce the impact of drive roller eccentricities on belt signal to start-of-scan signal timing, the perimeters of photoreceptor roller elements are sub-multiples of the photoreceptor length.Type: GrantFiled: July 26, 2000Date of Patent: September 24, 2002Assignee: Xerox CorporationInventors: Elias Panides, Joannes N. M. deJong, Lloyd A. Williams, Vittorio Castelli, Barry M. Wolf

Patent number: 5689767Abstract: An apparatus for maintaining a uniform temperature along its axis by increasing the heat transfer efficiency. The apparatus uses a sealed chamber containing a substantially pure working fluid in a two phase (liquid and vapor) condition. The vaporization and condensation of the fluid increases the heat transfer efficiency and tends to equalize temperature gradients in a body in contact with the apparatus. The apparatus is utilized in various locations in an electrophotographic printing machine and can be used as a pressure roll for a heat and pressure fuser, a support or drive roll for a photoreceptive member, a support member for a photoreceptor and a heat sink for a developer housing.Type: GrantFiled: October 31, 1995Date of Patent: November 18, 1997Assignee: Xerox CorporationInventors: Gerald A.

Patent number: 5212526Abstract: In an imaging process, a toned image layer on an image receptor is simultaneously transferred and fused to a recording medium. A radiation curable material is incorporated in the toned image layer such that when the toned image layer is irradiated, the radiation curable material is cured. The resulting cured material has greater adhesion to the toner material and the recording medium than to the surface of the image receptor. The apparatus for performing the above process is also disclosed.Type: GrantFiled: November 27, 1991Date of Patent: May 18, 1993Assignee: Xerox CorporationInventors: Gerald A. Domoto, Elias Panides
