ABSTRACT:
A printhead for an inkjet printer includes a wafer assembly defining spaced apart groups of ink supply channels; and groups of ink ejection nozzle arrangements extending from the wafer assembly and in fluid communication with respective ink supply channel groups, each group of ink ejection nozzle arrangements including a pair of rows of ink ejection nozzle arrangements. Each nozzle arrangement includes an ink ejection head from which an actuator tail extends. Each pair of rows of ink ejection nozzle arrangements are arranged such that the ink ejection heads of the ink ejection nozzle arrangements in a first row of the pair face toward and are adjacent to the ink ejection heads of the ink ejection nozzle arrangements in a second row.
