Patent number: 11433684Abstract: A print apparatus is disclosed. The print apparatus comprises a container-receiving unit for receiving a reusable print agent container; a print agent reservoir for storing print agent to be consumed by the print apparatus during a printing operation; a pump for transferring print agent between a reusable print agent container positioned in the container-receiving unit and the print agent reservoir; and processing circuitry. The processing circuitry is to operate the pump to transfer print agent of a first concentration from the reusable print agent container to the print agent reservoir; and, responsive to determining that a volume of print agent of the first concentration in the reusable print agent container has fallen below a threshold volume, operate the pump to transfer a volume of print agent of a second, lower concentration from the print agent reservoir to the reusable print agent container. A method and a machine-readable medium are also disclosed.Type: GrantFiled: August 22, 2018Date of Patent: September 6, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Peter Nedelin, Mark Sandler, Assaf Pines, Shai Lior

Patent number: 11409211Abstract: In one example of the disclosure, a first transfer of ink is made from a photoconductor to a blanket in contact with the photoconductor. The blanket is to cycle along a path. The first transfer occurs at a first arc of the blanket path. A second transfer of the ink is made from the blanket to a media in contact with the blanket. The second transfer occurs at a second arc of the blanket path. A heat source located adjacent to a third arc of the blanket path is utilized to heat an external surface of the blanket. The heating is to occur following the second transfer of the ink.Type: GrantFiled: October 8, 2020Date of Patent: August 9, 2022Assignee: HP Indigo B.V.Inventors: Peter Nedelin, Mark Sandler, Shai Lior

Patent number: 10864718Abstract: An embossing apparatus includes an embossing die that includes a printed relief pattern made up of multiple layers of a deposited material. A resilient surface presses media against the embossing die such that embossed features corresponding to the embossing die are formed in the media. A method for embossing media includes forming an embossing die by depositing multiple layers of ink on a impression layer to form a relief pattern and pressing media against the embossing die to transfer the relief image to the media.Type: GrantFiled: March 21, 2016Date of Patent: December 15, 2020Assignee: HP Indigo B.V.Inventors: Mark Sandler, Shai Lior, Eyal Peleg, Nati Sinuany, Dror Kella, Shahar Stein, George Trendafilov, Tsahi Rosenbaom

Patent number: 10859949Abstract: In an example, an apparatus is described that includes a photosensitive imaging plate, an intermediate transfer member, and a heating unit. The photosensitive imaging plate attracts a layer of printing fluid. The intermediate transfer member contacts the photosensitive imaging plate and receives the layer of printing fluid from the photosensitive imaging plate. The heating unit includes an array of individually addressable heating elements and heats the intermediate transfer member in a manner that is spatially selective along two axes: a first axis in a direction of a width of the intermediate transfer member and a second axis in a direction of a rotation of the intermediate transfer member.Type: GrantFiled: August 28, 2019Date of Patent: December 8, 2020Assignee: HP Indigo B.V.Inventors: Shai Lior, Mark Sandler, Peter Nedelin, Guy Hamou

Patent number: 10809650Abstract: An example method includes concentrating first printing liquid on a conveyor. Concentrating the first printing liquid produces liquid carrier having a low non-volatile solid concentration. The method also includes concentrating the liquid carrier having the low non-volatile solid concentration on a developer roller. Concentrating the liquid carrier having the low non-volatile solid concentration produces liquid carrier substantially free of non-volatile solids. The method also includes delivering the liquid carrier substantially free of non-volatile solids to a storage vessel.Type: GrantFiled: February 8, 2016Date of Patent: October 20, 2020Assignee: HP Indigo B.V.Inventors: Peter Nedelin, Shai Lior, Mark Sandler

Patent number: 10739704Abstract: In one example, a system for transferring an image from a photoconductor to a print substrate includes a transfer member having a removable blanket wrapped around a rotatable drum and a laser. The blanket has a light absorbing exterior surface to receive a liquid LEP ink image from the photoconductor and to release a layer of molten toner to a print substrate. As the drum rotates, the laser exposes a width of the exterior surface of the blanket carrying a liquid LEP ink image to a beam of coherent light that delivers enough power to transform the liquid LEP ink image into molten toner.Type: GrantFiled: August 7, 2019Date of Patent: August 11, 2020Assignee: HP Indigo B.V.Inventors: Mark Sandler, Peter Nedelin, Shai Lior
