Patent number: 11086253Abstract: During a print cycle of a print apparatus, a liquid print agent including a carrier fluid is applied to a photoconductive surface. A proportion of the carrier fluid in the liquid print agent on the photoconductive surface is reduced at a first location by removably collecting a portion of the carrier fluid from the liquid print agent applied to the photoconductive surface. During a non-print cycle of the print apparatus, the removably collected portion of the carrier fluid is added to the photoconductive surface at the first location.Type: GrantFiled: July 2, 2020Date of Patent: August 10, 2021Assignee: HP Indigo B.V.Inventors: Asaf Anufa, Ronen Bitan, Doron Schlumm, Shmuel Borenstain

Patent number: 10877403Abstract: An example method of performing a null cycle in a liquid electrographic printer is described. The method involves collecting, at a photo imaging plate cleaning station, imaging oil deposited on a photo imaging plate during a print cycle. During a null cycle, the photo imaging plate cleaning station is controlled to apply the collected imaging oil to the photo imaging plate.Type: GrantFiled: November 15, 2019Date of Patent: December 29, 2020Assignee: HP Indigo B.V.Inventors: Shmuel Borenstain, Shahar Stein, Asaf Anufa

Patent number: 10437177Abstract: In certain examples, a liquid electrophotographic printer has a compressive element. The compressive element removes a portion of carrier liquid from an inked image on an imaging element. The compressive element is selectively engageable and a controller disengages the compressive element for a first layer of liquid toner so as to retain carrier liquid in the first layer, and engages the compressive element for a subsequent layer of liquid toner so as to remove a portion of carrier liquid from the subsequent layer.Type: GrantFiled: January 22, 2019Date of Patent: October 8, 2019Assignee: HP Indigo B.V.Inventors: Shmuel Borenstain, Asaf Anufa
