  • Patent number: 12053982
    Abstract: A method of operating a printer identifies image areas in ink image content data that are likely to affected by airflow disturbances to produce ink blur within an ink image. Inkjets farthest from these areas are selected to eject ink drops into these areas to form portions of an ink image. The image areas identified as being likely to produce ink blur are the leading edge, trailing edge, and side edge of the ink image content data. The ink drops ejected by these selected inkjets and their satellites are less likely to be affected adversely by the airflow disturbances.

  • Patent number: 12051610
    Abstract: First and second chiplets are positioned along a surface to respectively cover first and second electrodes. The first electrode is activated to cause an attraction force between the first electrode and the first chiplet. The second electrode is deactivated allowing the second chiplet to rotate on the surface. While the first electrode is activated and the second electrode is deactivated, a rotation field is applied to cause the second chiplet to be oriented at a desired orientation angle, the first chiplet being prevented from rotating by the attraction force.
