ABSTRACT:
Disclosed is an ink jet printhead apparatus for modulating drop size. Drop size modulation is achieved by providing an ink jet printhead chip for use in an ink jet printhead having a cavity in communication with a supply of ink and a nozzle. The chip includes an unitary actuator having a first active section and a second active section. The first and second active sections are defined at a substantially equal distance from the nozzle by a location of attachment of at least three conductors.
