Publication number: 20120189364Abstract: A method of reducing drag on a rotatable web drive member for driving a web in an electrophotographic printer includes spacing a plurality of rotatable, driven tensioning members, divided into two groups, along the web. Each tensioning member exerts a respective drag force on the web drive member through the web while maintaining tension on the web between adjacent members, and has a surface speed at a point of contact with the web. Each tensioning member in the first group is rotated with a greater surface speed than each member in the second group. Members of the first group thus exert a negative drag (overdrive) and members of the second group exert a positive drag (underdrive), and the total drag on the web drive member is less than the sum of the magnitudes of the respective drags exerted by the tensioning members.Type: ApplicationFiled: January 21, 2011Publication date: July 26, 2012Inventors: Andrew Peter Kittleson, Timothy John Young

Patent number: 8228525Abstract: A method of digital printing in which each of the page images of a print job with a large number of sequential pages to be printed is classified as to the job or document type. Upon occurrence of a fault in printing, upon fault clearance and resumption of printing, only those pages having the same classification as the pages involved in the fault are reprinted in sequence from the fault.Type: GrantFiled: July 16, 2007Date of Patent: July 24, 2012Assignee: Xerox CorporationInventors: Amy Moormann Zaremski, Dragana Pavlovic, Bradford Freeman

Publication number: 20120183338Abstract: A deburring device includes a first contact member that rotates in contact with a first end of a transported recording medium in a width direction, a second contact member that rotates in contact with a second end of the transported recording medium in the width direction, a press member that presses the transported recording medium toward the first and second contact members, and a pushing member that produces a pressing force such that the recording medium is pressed between the first and second contact members and the press member. The first contact member and the second contact member are arranged to pull the recording medium outward in the width direction of the recording medium during rotation.Type: ApplicationFiled: August 22, 2011Publication date: July 19, 2012Applicant: FUJI XEROX CO., LTD.Inventor: Yusuke KANAI
