Abstract: An ink jet printing system includes: a print head including multiple fluid ejectors, each fluid ejector including a corresponding nozzle defined in a bottom surface of the print head, each nozzle configured to eject a liquid onto a substrate. The nozzles can be arranged in an array including four or more parallel rows, the rows extending along a direction that is perpendicular to a process direction of the ink jet printing system. The process direction is the direction of relative motion between the print head and the substrate during operation of the print head. A spacing between adjacent nozzles in each row can be such that a nozzle density in each row is less than 75 nozzles per inch. A spacing between adjacent rows in the process direction can be less than the spacing between adjacent nozzles in each row.

Abstract: An inkjet printer printhead, member thereof, or other component has an internal cavity that has a protective coating. Further surfaces of the component may have the protective coating. To make the protective coating, a target thickness for a film of HfO2 (hafnia) is selected, that will avoid formation of pinholes, thin spots and nodule growth. Using atomic layer deposition (ALD), with the processing adjusted for the target thickness, the film of HfO2 is deposited as a conformal layer on the component, including on a surface of the internal cavity, to form a coated component. A non-wetting coating can be included over the film of HfO2.
