Ink jet printhead for dropsize modulation

摘要

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 actuator (52) having a first active section (54) and a second active section (56). The first and second active sections are positioned at a substantially equal distance from the nozzle. <IMAGE>
