Fluid ejecting actuator for multiple nozzles of a printhead

摘要

A nozzle arrangement for an inkjet printhead, the nozzle arrangement comprising: a chamber with a plurality of ink ejection ports; and, a thermal bend actuator for selectively ejecting ink from any one of the ejection ports. Constructing the nozzle arrangement such that a single actuator can eject drops from multiple nozzles requires less drive circuitry than a printhead that has a single actuator for each nozzle. This allows a high nozzle packing density and consumes less power.
