Printhead with multiple actuators in each chamber
Abstract:
An inkjet printhead with multiple actuators and respective nozzles in each chamber, so that each actuator activates simultaneously from the same drive signal. By puffing multiple actuators in a single chamber, and providing each actuator with a corresponding nozzle (or nozzles), each nozzle ejects drops of smaller volume, and having different misdirections. Smaller drops with differing misdirections are less likely to create any visible artifacts.
