Patent number: 6792220Abstract: A method and apparatus are provided to calibrate a xerographic print engine toner concentration sensor to accurately control the toner concentration to a specified operating target. At least two control patches are imaged onto a photoreceptor. Each patch has a different voltage level where the voltage levels are the difference between the exposure discharge voltage and the developmental roll voltage. The relative reflectivity of each patches is obtained. The latent patches are repeatedly developed at different toner concentrations. The reflectivities of the patches formed at the same toner concentration are combined to obtain a combined reflectivity for that toner concentration. As a result, a toner concentration curve is obtained that has an improved response relative to the toner concentration curves that correspond to each of the individual voltage levels.Type: GrantFiled: January 15, 2003Date of Patent: September 14, 2004Assignee: Xerox CorporationInventors: Stephen F. Randall, Song-feng Mo, Wendy K. Apton, David C. Craig, Patricio G. Medina, Patrick J. Walker, Ralph A. Shoemaker

Patent number: 6788086Abstract: Scanning probe systems, which include scanning probe microscopes (SPMs), atomic force microscope (AFMs), or profilometers, are disclosed that use cantilevered spring (e.g., stressy metal) probes formed on transparent substrates. When released, a free end bends away from the substrate to form the cantilevered spring probe, which has an in-plane or out-of-plane tip at its free end. The spring probe is mounted in a scanning probe system and is used to scan or otherwise probe a substrate surface. The probes are used for topography, electrical, optical and thermal measurements.Type: GrantFiled: November 19, 2003Date of Patent: September 7, 2004Assignee: Xerox CorporationInventors: Thomas Hantschel, Eugene M.

Patent number: 6788906Abstract: Two temperature areas are set at a higher temperature side and at a lower temperature side of target temperature respectively. The power stage of the temperature areas at the higher temperature side is set to −1 and the power stage of the temperature areas at the lower temperature side is set to +1. Thus, a current value is varied little and generation of flicker can be reduced. Further, A temperature can be always converged into the target temperature. When a temperature is in a temperature area near to the target temperature, the power stage is maintained except for a case in which a temperature has passed through a temperature area other than this near temperature area and the target temperature area and enters this near temperature area for the first time. Thus, an amplitude of power can be suppressed.Type: GrantFiled: March 17, 2003Date of Patent: September 7, 2004Assignee: Fuji Xerox Co., Ltd.Inventors: Yukio Suzuki, Teruo Kaneko, Naoki Honma, Kunihiro Maie, Kouji Tsutsumi

Publication number: 20040172602Abstract: The present invention provides increased processing efficiency for service of performing predetermined processes on document data through cooperation among the processes over a network. If an error exists during document input in an input plug-in element before a start of rule-based processing, when documents are captured from the input plug-in element, contents of the error are stored in an error history memory, and documents normally inputted are subjected to processing of processing plug-in and output plug-in elements according to the rule. Also when an error occurs during the rule-based processing, the contents of the error are stored in the error history memory, and the rule-based processing is continued for normal documents. Error histories are referred to, and if an error exists, the error contents are reported on the basis of the error histories.Type: ApplicationFiled: September 15, 2003Publication date: September 2, 2004Applicant: FUJI XEROX CO., LTD.Inventors: Hiroshi Iida, Tohru Mori, Kenji Kawase, Hiroomi Ichiba, Satoshi Kaito, Reiko Aoyama, Noriyuki Abe, Nobuyuki Takao, Yumiko Koga, Mitsushige Oguri, Takanobu Suzuki
