摘要: A fluid ejection device includes a substrate, drop generators formed on the substrate at a high density, primitive select lines, and a ground line. The drop generators are arranged in primitives of drop generators. Each drop generator includes a heater resistor having a high resistance. Each primitive select line is separately electrically coupled to a corresponding one of the primitives and is configured to connect to a power source. The ground line is electrically coupled to all of the primitives.

摘要: For an inkjet printing apparatus having a large number of ink ejectors, it is desirable to have as few as possible interconnections to the ink ejectors. Sharing electrical ground returns between related ink ejector primitive groups with spaced apart terminals provides a reduction in interconnections while offering redundancy in the interconnection.

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.
