Patent number: 10802422Abstract: 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: March 1, 2017Date of Patent: October 13, 2020Assignee: HP Indigo B.V.Inventors: Peter Nedelin, Mark Sandler, Shai Lior

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
