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： The present disclosure relates to an inkjet printhead having a plurality of drop generators responsive to drive current and address signals for dispensing ink. The inkjet printhead includes first and second drop generators disposed on the printhead with each of the first and second drop generators configured to receive drive current from a drive current source. Each of the first and second drop generators is configured to receive address signals from a common address source. The inkjet printhead further includes a switching device connected between the common address source and each of the first and second drop generators. The switching device is responsive to enable signals for selectively providing the address signal to only one of the first and second drop generators.
