Patent abstract
An inkjet nozzle with a chamber defined by a plunger spaced from an ejection nozzle. An actuator moves the plunger towards the nozzle to eject drops of ink. Ejecting ink from the nozzle with a reciprocating plunger and simple actuating mechanism is energy efficient and offers high speed operation. With relatively low power consumption, the printhead can be easily extended to pagewidth.
