Patent ID: 7841703

Claim:
A printhead comprising a plurality of rows of print nozzles, each print nozzle being defined as a unit cell having first and second drive circuitry for that print nozzle respectively positioned at separate regions of that print nozzle with an ejection nozzle therebetween, wherein the unit cells in each row are rotated 180 degrees relative to the respective positions of the unit cells in each adjacent row such that for a first row and a second row which are adjacent one another the respective first circuitry are adjacent each other and for the second row and a third row which are adjacent one another the respective second circuitry are adjacent each other, and wherein the first drive circuitry of a cell unit is a control logic for controlling whether and when the cell unit ejects ink, and the second drive circuitry of the cell unit is a drive transistor circuit for providing electric current to an actuator of the cell unit that ejects ink when enabled by the control logic.
