Publication number: 20240152685Abstract: An input/output of a system receives an electronic file comprising text. A processor of the system identifies keywords in the text. The processor correlates the keywords to music attributes and matches the music attributes to musical works. The processor determines computer network locations of the musical works. The processor also adds links to the network locations of the musical works to the electronic file to create a music-enhanced electronic file. The input/output outputs the music-enhanced electronic file that now contains the links to the musical works.Type: ApplicationFiled: November 3, 2022Publication date: May 9, 2024Applicant: Xerox CorporationInventors: Dara N.

Patent number: 11890873Abstract: An inkjet printer detects vibrations within the printer and compensates for the detected vibrations by adjusting a gap between the printheads and the media transport. Additionally, the inkjet printer detects media sheet heights that may cause damage as they pass through the print zone of the printer and adjusts the gap to enable the media sheets to pass through the print zone without contacting the printheads. A method of operating an inkjet printer so configured is also disclosed.Type: GrantFiled: January 31, 2022Date of Patent: February 6, 2024Assignee: Xerox CorporationInventors: Ron E. Dufort, Elizabeth L Barrese, Dara N. Lubin, Matthew J. Ochs

Patent number: 11801680Abstract: A method of operating a printer iteratively performs printhead purges and test pattern analysis until either every printhead has a number of inoperative inkjets that is less than a predetermined threshold or a maximum number of iterations is reached. An error message is generated for each printhead having a number of inoperative inkjets that is greater than the predetermined threshold. The iterative performance of the printhead purges and test pattern analysis is performed automatically prior to the commencement of printing operations with the printer to remove subjective and time-consuming analysis by a printer operator.Type: GrantFiled: January 20, 2022Date of Patent: October 31, 2023Assignee: Xerox CorporationInventors: Elizabeth L.

Publication number: 20230068167Abstract: A processor identifies print defect locations where printing defects occur and a assigns different sensitivity values to different zones of a job image being prepared for printing by a printing engine. The processor changes the orientation of the job image to a revised orientation, relative to print media, to avoid locating one or more high-sensitivity zones of the job image in the print defect locations. The high-sensitivity zones are ones of the zones having a sensitivity value above a threshold sensitivity value. The printing engine prints the job image on the print media at the revised orientation.Type: ApplicationFiled: August 26, 2021Publication date: March 2, 2023Applicant: Xerox CorporationInventors: Dara N.

Patent number: 11453162Abstract: A system treats uneven surfaces of additive manufactured objects to improve the transparency and glossiness of the surfaces. The system operates an actuator to dip the additive manufactured object into a bath of fluid material that is the same as the material used to form the uneven surface to smooth the surface of the object and operates a sprayer to apply another fluid material to a surface of the object that is identified as being rougher based on the object's geometric data. A heater is provided to dry non-UV curable material applied to the object and a source of UV radiation is provided to cure UV curable material applied to the object.Type: GrantFiled: March 3, 2020Date of Patent: September 27, 2022Assignee: Xerox CorporationInventors: Ron E.

Patent number: 11327700Abstract: Various systems and methods maintain a print job of a user in a print queue and identify the user approaching a printing device using a user identification device operatively connected to the printing device. Such systems/methods alter the position of the print job within the print queue (e.g., to a higher priority position) or even begin printing the print job when the user identification device identifies the user approaching the printing device (i.e., before the user reaches the printing device). Systems and methods can also identify the urgency of the user using the user identification device. The amount that the print queue is altered can be based on the amount that the urgency of the user is elevated.Type: GrantFiled: January 6, 2021Date of Patent: May 10, 2022Assignee: Xerox CorporationInventors: Elizabeth M. Crossen, Ron E. Dufort, Dara N. Lubin

Patent number: 10589950Abstract: A gravity-assisted registration system suited to use in a printing device includes a transport member with a surface on which an associated sheet is translated in a process direction. The surface defines an angle with respect to horizontal in a cross-process direction. A registration wall, adjacent a lower end of the surface, defines a registration edge for registering the sheet. A drive mechanism drives at least one rotation mechanism, for translating sheet in the process direction, each rotation mechanism including at least one drive member with an axis of rotation parallel to the surface in the cross-process direction, Each drive member includes a sliding mechanism, at a periphery of the drive member, enabling the sheet to slide, under gravity, on the surface, toward the registration wall into an alignment position, in contact with the registration wall.Type: GrantFiled: March 29, 2018Date of Patent: March 17, 2020Assignee: XEROX CORPORATIONInventors: Roberto A.

Patent number: 10562211Abstract: A system for manufacturing a three-dimensional object facilitates the removal of support material from the object. The system includes a controller configured to move a platen to position the object at a position opposite a microwave radiator and then operate the microwave radiator to change the phase of the support material from solid to liquid. The controller either monitors the expiration of a predetermined time period or a temperature of the object to determine when the microwave radiator operation is terminated. The microwave radiation does not damage the object because the support material has a dielectric loss factor that is greater than the dielectric loss factor of the object.Type: GrantFiled: April 17, 2018Date of Patent: February 18, 2020Assignee: Xerox CorporationInventors: Ron E. Dufort, Erwin Ruiz, Linn C. Hoover, David K. Ahl, Patrick J. Howe, Andrew W. Hays

Patent number: 10391712Abstract: A method of operating a cleaning system removes support material from parts made by a three-dimensional printer. The method operates the cleaning system to correlate data for features on a part located within a receptacle with structural data in a file used by the three-dimensional printer to fabricate the part. The method then operates one or more actuators to locate a fluid directing nozzle pneumatically connected to a pressurized fluid source opposite areas containing support material and operates the pressurized fluid source to enable pressurized fluid to be directed by the fluid directing nozzle at the support material. The method includes generating image data of the cleaned areas with an image sensor so the removal of the support material can be confirmed, and if an area is not sufficiently cleaned, the cleaning operation can be repeated.Type: GrantFiled: February 18, 2016Date of Patent: August 27, 2019Assignee: Xerox CorporationInventors: Linn C.

Patent number: 10350873Abstract: A method of manufacturing a three-dimensional object facilitates the removal of support material from the object. The method includes forming at least a portion of a support for the object with support material containing nanoparticles of a material that readily converts microwave energy into heat. The object and support are moved to a position opposite a microwave radiator and the microwave radiator is operated to begin a change of the phase of the portion of the support material containing the nanoparticles before beginning a change of the phase of a portion of the support made from the support material alone. A controller either monitors the expiration of a predetermined time period or a temperature of the object to determine when the microwave radiator operation is terminated.Type: GrantFiled: November 11, 2015Date of Patent: July 16, 2019Assignee: Xerox CorporationInventors: Ron E.
