Patent number: 11640271Abstract: A system and method are provided which enable overriding a custom color callout in a print job. Provision is made for a user to associate a unique ID with a custom color callout in a print job, e.g., during generation of the print job or at the printer. The custom color callout provides for a part of the print job to be rendered with a specific custom colorant, e.g., by identifying the name of the custom colorant. The unique ID is associated, in memory, with a custom colorant station of a print engine, independent of any custom colorant that may be housed in the custom colorant station. The method further includes identifying the custom colorant station of the print engine associated with the unique ID and sending the print job in a format for printing to the print engine for printing the part of the print job with a first custom colorant housed in the identified custom colorant station.Type: GrantFiled: June 25, 2021Date of Patent: May 2, 2023Assignee: XEROX CORPORATIONInventors: Barry K. Ayash, Mark Rule, David B. Montfort

Patent number: 9604478Abstract: Beam strength and curl characteristics of sheets of print media change based not only on paper weight, but also on environmental conditions, such as humidity. Printers herein include a printing engine positioned to receive sheets of print media from a storage container. Sheet transport elements are positioned to transport the sheets from the storage through the printing engine. A sensor contacts one of the sheets, and the sensor detects a beam strength and curl characteristics signature profile of the sheet tested. Then, a processor (that is electrically connected to the sensor and the sheet transport elements) adjusts how the sheet transport elements contact the sheets (adjusts the angle, speed of, and force applied by, the sheet transport elements) based on the beam strength and curl characteristics signature profile.Type: GrantFiled: June 16, 2016Date of Patent: March 28, 2017Assignee: Xerox CorporationInventors: David B.

Patent number: 9597839Abstract: A printer compensates for printing errors occurring during production of the layers for the formation of an object in a three-dimensional printer. The printer includes an optical sensor that generates data corresponding to edges of each layer of the object after each layer is printed. Differences between the raster data used to eject the material to form a layer and the data received from the optical sensor are used to modify the raster data that operates a printhead to form a next layer in the object.Type: GrantFiled: June 16, 2015Date of Patent: March 21, 2017Assignee: Xerox CorporationInventors: Dara N. Lubin, John T. Buzzelli, Ron E. Dufort, Kevin St. Martin, David B. Montfort

Patent number: 8908198Abstract: A system and method for automatically rendering labeling service prints with print engine parameters. An auto-labeling application can be configured in association with a print engine controller for labeling the service prints with the print engine parameters via a built-in marker integrated with a fault multi-function device. A portable inline marker can also be separately attached to a baffle assembly of the fault device and connected to the print engine controller via a connector in order to receive the print engine parameters from the print engine controller. A setup routine configured with the auto-labeling application can be employed to customize the service print labels in a modular format and the parameters can be appended to each other based on the information required to troubleshoot the fault multi-function device.Type: GrantFiled: November 16, 2010Date of Patent: December 9, 2014Assignee: Xerox CorporationInventors: Eliud Robles Flores, David B.

Patent number: 8781351Abstract: Systems and methods are described that facilitate automatically and uniformly depositing a marking material on transfer assist blade (TAB) petals to improve TAB pressure profile accuracy. A TAB liftoff timing value is adjusted in non-volatile memory (NVM) to delay TAB liftoff beyond a trailing edge of a page on which an oversized (in the process direction) image being printed. Toner deposited on a photoreceptor belt beyond the trailing edge of the page is picked up by the TAB petals once the trailing edge of the page has passed the TAB. The TAB is then disengaged and re-engaged against a backside of a next page, where the TAB petals deposit the uniformly acquired toner to generate the TAB pressure profile.Type: GrantFiled: March 14, 2011Date of Patent: July 15, 2014Assignee: Xerox CorporationInventors: John R.

Patent number: 8447210Abstract: As set forth herein, a reusable transfer assist blade (TAB) assembly includes a replaceable blade assembly that is locked into position between a clamp assembly and an extruded portion of the TAB assembly. When the blade assembly requires replacement, spring tables on the clam assembly are biased upward to release the clamp assembly from the extruded portion, and the clamp assembly is rotated about a clamp tab-clamp pocket interface at the top of the TAB assembly. The blade assembly is removed and replaced, the clamp assembly is rotated back into position against the extruded portion, and the spring tabs re-engage interlocking features on the extruded portion to lock the replacement blade in position. The expensive extruded portion and clamp assembly are thus reused and the inexpensive blade assembly is discarded or recycled.Type: GrantFiled: September 20, 2010Date of Patent: May 21, 2013Assignee: Xerox CorporationInventors: David B. Montfort, Donald C. Koch, Eliud Robles Flores, John R. Falvo

Patent number: 8403458Abstract: A latching assembly for mounting a printhead to a plate assembly of a printing machine includes a first elongated actuator and a second elongated actuator defining a bore to slidably receive the first actuator. A first spring is disposed between the heads of the first and second actuators, while a second spring is disposed between the second actuator and the printhead to exert a clamping force. A cam mechanism is defined between the plate assembly and the ends of the actuators that is configured to draw the head of the first actuator toward the plate assembly upon rotation of the first actuator and to independently draw the head of the second actuator toward the plate assembly upon rotation of said second actuator. Movement of said first actuator exerts an initial clamping force while movement of the second actuator produces a final clamping force on the printhead.Type: GrantFiled: May 6, 2011Date of Patent: March 26, 2013Assignee: Xerox CorporationInventors: David B. Montfort, Matthew D. Savoy

Patent number: 8340541Abstract: An electrophotographic marking apparatus and an automatic method for automatically scanning and correcting TAB pressure non-uniformity using a cross-process uniformity controller and a closed loop system. The TAB is contacted with an image on a photoreceptor surface to leave its imprint or footprint on the image, which are analyzed for TAB performance and pressure. This method uses a CPUC full width array in conjunction with a software version for assessing TAB performance. This method continuously monitors the TAB performance during the running of a marking apparatus.Type: GrantFiled: December 23, 2009Date of Patent: December 25, 2012Assignee: Xerox CorporationInventors: John R. Falvo, Eliud Robles-Flores, David B Montfort

Patent number: 8276468Abstract: According to aspects of the embodiments, an apparatus and method is proposed to detect nip width by use of at least one piezoelectric (PZT) crystal embedded into a roll at both the inboard and outboard ends. A piezoelectric (PZT) crystal generates a charge when subjected to a load and when the load is released. The PZT generate signal is channeled to the ends of the roller such as with a brush contact to be processed and used within machine control. The duration measure from application and released of the load is indicative of the dwell time and the amplitude PZT generate signal is a function of the pressure. The time and amplitude of the PZT signal can be calibrated to correlate directly to nip width or pressure and tracked in machine control.Type: GrantFiled: January 18, 2011Date of Patent: October 2, 2012Assignee: Xerox CorporationInventors: Brian John McNamee, David B.
