Publication number: 20250073996Abstract: A 3D printer configured to print a 3D part includes an ejector having a nozzle that is configured to eject drops of a build material. The 3D printer also includes a build plate positioned below the nozzle. The drops land and solidify on the build plate to form at least a portion of the 3D part. The 3D printer also includes a first heater positioned under or within the build plate. The first heater is configured to heat the build plate and the 3D part thereon. The 3D printer also includes a second heater positioned laterally-offset from the build plate. The second heater is configured to heat a volume of air between the nozzle and an upper surface of the 3D part. The 3D printer also includes an enclosure. The nozzle, the build plate, the first heater, and the second heater are positioned at least partially within the enclosure.Type: ApplicationFiled: August 29, 2023Publication date: March 6, 2025Applicant: XEROX CORPORATIONInventors: Erwin Ruiz, Timothy G. Shelhart, Nadish Anand, James Root, Derek A. Bryl, Brian Gillis, Matthew R. McLaughlin, Peter Knausdorf, Wade F. Thomas, Kareem Tawil, Prince Joseph, Fredrik Perman

Patent number: 9606484Abstract: An improved fuser includes a heater which provides uniformity at the surface of a fuser roll that contacts an imaged sheet. The heater is configured to include a common tap at the center of a single heating trace. This allows for the benefits of a single trace configuration well while simultaneously providing a dedicated common line that does not have to be switched around.Type: GrantFiled: March 8, 2016Date of Patent: March 28, 2017Assignee: Xerox CorporationInventors: Christopher A Jensen, Tab Alan Tress, Brian Gillis

Publication number: 20120051807Abstract: An improved fuser includes a heater which provides uniformity at the surface of a fuser roll that contacts an imaged sheet. The heater is configured to include a single resistive element shaped to heat multiple sheet sizes with independently controllable conductive traces connected to outer segments of the resistive element and adapted to supply electricity to separate sections of the resistive element in accordance with the size of sheet being fed through the fuser center registered and without the need for cold spot compensation.Type: ApplicationFiled: August 27, 2010Publication date: March 1, 2012Applicant: XEROX CORPORATIONInventors: Tab A. Tress, Robert S. Pawlik, Brian Gillis, Nathan E. Smith

Patent number: 8121528Abstract: Apparatuses useful for printing and methods of treating marking material on media are provided. An exemplary embodiment of the apparatuses useful for printing includes a roll including a first outer surface; a continuous belt including an inner surface and a second outer surface forming a nip by contact with the first outer surface, the belt being driven to rotate by rotation of the roll; a heater disposed inside of the belt and comprising a first heating surface contacting the inner surface of the belt at the nip; and a heating fin in thermal contact with the heater, the heating fin including a second heating surface extending circumferentially in contact with a pre-nip portion of the inner surface of the belt. Thermal energy is conducted from the heater to the heating fin. The second heating surface pre-heats the pre-nip portion of the belt before the pre-nip portion is rotated to the nip, and the first heating surface of the heater heats the pre-heated, pre-nip portion at the nip.Type: GrantFiled: June 24, 2009Date of Patent: February 21, 2012Assignee: Xerox CorporationInventors: Robert S. Pawlik, Nathan Smith, Brian Gillis, Thomas C. Fowler
