Patent number: 6819890Abstract: A fuser system of a xerographic device includes at least one set of a fuser member and a pressure member having a nip width therebetween, the nip width being set to within a specification nip width range, at least one sensor for monitoring the velocity of at lease one of the fuser member, the pressure member and a media passing through the nip, a processor that receives the velocity data from the at least one sensor and that determines a current nip width from the velocity data and compares the current nip width to the specification nip width range, and a nip width adjustment device in communication with the processor, which adjusts the current nip width to be within the specification nip width range. To offset changes in nip width due to hardening/softening of a fuser member material, or to provide a means to measure nip width in order to enable fusing setpoints using multiple nip width specifications, a method for closed loop control of nip width is enabled by the fuser system.Type: GrantFiled: December 19, 2003Date of Patent: November 16, 2004Assignee: Xerox CorporationInventors: Donald M.

Patent number: 6169874Abstract: A fuser baffle which helps to minimize or eliminate sheet wrinkle by a fuser. A small “saddle” is added to the center section of the inlet to the fuser on the baffle surface which last contacts and controls the sheet before entry into the fuser nip. The saddle removes most of the corrugation along approximately 90 to 95% of the centermost portion of the sheet. Any remaining corrugation at the inboard and outboard ends is removed by the fuser flare. The baffle is applicable to any fusing device which uses localized pressure to fix an image to a sheet.Type: GrantFiled: January 8, 1998Date of Patent: January 2, 2001Assignee: Xerox CorporationInventors: Lisbeth S. Quesnel, David P. Van Bortel

Patent number: 5195689Abstract: A binding tape cartridge in which a reel of binding tape is packaged in a moisture impervious bag. The bag has an exit port through which the tape is advanced. A seal, mounted in the exit port, permits the passage of tape therethrough while maintaining the interior substantially dry. This projects the binding tape from moisture, reducing the possibility of tape delamination.Type: GrantFiled: June 15, 1990Date of Patent: March 23, 1993Assignee: Xerox CorporationInventors: Ted A. Beer, Paul N. Richards, David P. Van Bortel
