Abstract: An inkjet printer includes an electrode in either a printhead or an image receiving member that is operatively connected to a waveform generator. During operation, a controller operates the waveform generator to generate an electrostatic field between the printhead and the image receiving member during operation of inkjets in the printhead to eject ink drops. The controller operates the waveform generator to reduce an amplitude of the electrostatic field while the ink drops travel toward the image receiving member during a time when satellite ink drops can be formed from the ejected ink drops. The controller subsequently operates the waveform generator to generate the electrostatic field while the ink drops are in flight after formation of the satellite to accelerate the ink drops and satellites towards the image receiving member.

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.
