Patent number: 11334004Abstract: In an example, a method includes forming a print agent pattern on an image forming surface and transferring the print agent pattern from the image forming surface to an intermediate transfer member. In a first mode of operation in which a printable substrate is not between the intermediate transfer member and a cleanable medium, the print agent pattern may be transferred from the intermediate transfer member to the cleanable medium and then cleaned from the cleanable medium. In a second mode of operation, the printable substrate may be provided between the intermediate transfer member and the cleanable medium, and the same print agent pattern or a different print agent pattern may be transferred from the intermediate transfer member to the printable substrate.Type: GrantFiled: October 28, 2020Date of Patent: May 17, 2022Assignee: HP Indigo B.V.Inventors: Eyal Bachar, Ido Gorgani, Kostin Cusiner, Reut Avigdor
