  • Patent number: 11850842
    Abstract: A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead arranged to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system comprises an air supply unit comprising air flow guide structure extending into the opening of the carrier plate between the carrier plate and the printhead to flow air through the opening. The air flow control system controls the air supply unit to selectively flow the air based on a location of a print medium relative to the printhead.

  • Patent number: 11853629
    Abstract: A method of operating an inkjet printer identifies a thermal load that will be imposed on the printheads in the inkjet printer during execution of a print job and identifies a remedial action to reduce the thermal load if the thermal load increases the temperature of the printheads above an upper threshold of a predetermined temperature range. The thermal load is identified from the ink image content data for the print job, the print job parameters for the print job, and environmental condition measurements received from sensors in the printer. The remedial actions include manipulation of the print job queue, alteration of print job parameters, and active cooling to remove heat from the printheads or media within the printer.

  • Publication number: 20230398778
    Abstract: A method of operating a printer identifies image areas and image features in ink image content data that are likely to produce ink blur within an ink image. The ink image content data for these areas and features is modified to attenuate the appearance of ink blur. The image areas identified as being likely to produce ink blur are the trailing edge and the side edges of the ink image content data. The modification of the ink image content data for the features and predetermined areas improves the quality of the printed ink image.

  • Publication number: 20230395429
    Abstract: Depositing a seed layer after formation of the MD in order to reduce or prevent epitaxial growth of the seed layer toward the MD. For example, the seed layer may be deposited using CVD and conformal dry etching. In some implementations, the seed layer may be formed of ruthenium (Ru), molybdenum (Mo), or tungsten (W). Accordingly, the seed layer helps reduce or prevent seam formation in the VG, which reduces resistance of the VG by allowing for bottom-up metal growth. Additionally, current leakage from the VG to the MD is reduced or even prevented. As a result, device performance and efficiency are increased and breakdown voltage of the gate structure is also increased. Additionally, because electrical shorts are less likely, yield is increased, which conserves power, raw materials, and processing resources that otherwise would have been consumed during manufacture.

  • Publication number: 20230302833
    Abstract: A method of operating a printer evaluates the effect of printing a print job with two different orientations of the image content data for the print job. The orientation that produces the least increase in the cross-process direction displacement error for the inkjets in the printer is selected for printing the print job. By attenuating the increase in cross-process direction displacement error, the interval between printhead maintenance operations is increased.
