Abstract
Systems and methods of ejecting ink drops from an inkjet printer are disclosed. The systems and methods can include a printhead with one or more actuators with associated nozzles and membranes. A voltage waveform can be applied to the actuators to fill the actuators with a volume of ink and eject the ink through the nozzles as ink drops. The voltage waveform can have associated pre-fill voltage to fill the actuator with ink and a firing voltage to eject the ink. The actuator membranes can have multi-height dimples to protect the membranes from contacting electrodes and reduce the electric field.
