Patent number: 9082063Abstract: A system and method are provided for implementing selectable roll positioning for web printing in devices, including post processing devices, for advanced image forming systems. A selectable drive system for continuous feed or web material image receiving medium substrate can “with the flip of a switch” transition the drive system from a tensioned web (transport) pulling system in a downstream device to a slack web nip-drive system as may be dictated by other system and/or operating characteristics. The selection of a particular drive method is based on a constitution of the continuous feed or web material image receiving media; a composition of a marking material deposited on the continuous feed or web material image receiving media; or a post-processing technique that the continuous feed or image receiving media, as marked, may undergo in the production of an output document.Type: GrantFiled: July 17, 2013Date of Patent: July 14, 2015Assignee: Xerox CorporationInventors: Joseph M.

Patent number: 6227539Abstract: In a mailboxing system in which the different numbers and types of printed sheets being printed by the different users of a shared users printer are separately stored in different assigned mailbox bins in an array of mailbox bins, there is provided a system for automatically changing the spacing between selected adjacent bins to provide selectably different sheet stacking capacities for different bins for the different numbers of printed sheets being stored in the respective bins of different users. With this system the bin capacity can also be automatically reduced when the sheets are removed from that bin. Greatly increased overall and individual bin sheet stacking capacity is thus provided for the same overall system size as compared to conventional fixed spacing bins. Also, many more print jobs can be stored in the same user-assigned bin instead of having to split up large print jobs into other, overflow, bins.Type: GrantFiled: October 21, 1998Date of Patent: May 8, 2001Assignee: Xerox CorporationInventor: Joseph J.

Patent number: 6024682Abstract: An improved sheet folder for flimsy printed sheets with an automatic fold position correction system. The folder may have an input sheet feeder, a fold chute with a chute entrance, reversible sheet feeding rollers in the fold chute adjacent to the chute entrance, fold rollers, a folded sheets output path, and a sensor system for sensing the length of folded sheets in the folded sheets output path. A sheet to be folded is may be partially fed into the fold chute, engaged by the reversible rollers, and fed thereby further into the chute by a selected distance corresponding to a desired folding position along the sheet. Then, the reversible rollers are stopped at a selected sheet stopping position and reversed to feed the sheet into the fold rollers, cooperatively with the input sheet feeder. The fold rollers feed the folded sheet into the folded sheets output path.Type: GrantFiled: November 23, 1998Date of Patent: February 15, 2000Assignee: Xerox CorporationInventors: Barry P.
