    摘要： An ink jet print head with a substrate defining an ink aperture. A number of ink energizing elements are located on the major surface of the substrate. A barrier layer is connected to the upper surface, and peripherally encloses an ink manifold. The barrier encompasses the ink aperture. An orifice plate is connected to the barrier layer, spaced apart from the substrate's major surface, enclosing the ink manifold. The plate defines a number of orifices, each associated with a respective ink energizing element. The ink manifold is an elongated chamber having opposed ends defined by end wall portions of the barrier layer. The barrier end wall portions each have an intermediate end wall portion protruding into the manifold. Columnar structures placed at predetermined locations, including locations at the end of the ink aperture, and extending from the major surface to the orifice plate control the migration of coalescing bubbles.

    摘要： An ink jet printhead includes a printhead substrate having a plurality of thin film layers and four side by side columnar arrays of drop generators formed in the printhead substrate and extending along a longitudinal extent. Each columnar array has drop generators that are separated by a drop generator pitch P. The drop generators produce ink drops having a drop volume that enables single pass printing of a resolution that is 1/(4P) dpi along a print axis parallel to the longitudinal extent. Four columnar arrays of FET drive circuits formed in the printhead substrate are employed to energize corresponding columnar arrays of drop generators.

    摘要： An ink jet printhead includes a printhead substrate having a plurality of thin film layers and three side by side columnar arrays of drop generators formed in the printhead substrate and extending along a longitudinal extent. Each columnar array has ink drop generators that are separated by an ink drop generator pitch P. The ink drop generators produce ink drops having an ink drop volume that enables multi-pass printing of a resolution that is not less than 1/(2P) dpi along a print axis parallel to the longitudinal extent. Three columnar arrays of FET drive circuits formed in the printhead substrate are employed to energize corresponding columnar arrays of ink drop generators.

    摘要： A narrow ink jet printhead having four columnar arrays of ink drop generators configured for monochrome single-pass printing at a print resolution having a media axis dot spacing that is less than the columnar nozzle spacing of the ink drop generators. The ink jet printhead more particularly includes high resistance heater resistors and efficient FET drive circuits that are configured to compensate for variation in parasitic resistance presented by power traces.
