Abstract

See full text

Printheads and methods of operation. In one embodiment, a printhead includes a plurality of jetting channels comprising first jetting channels configured to jet a first print fluid and second jetting channels configured to jet a second print fluid, and a driver circuit communicatively coupled to actuators of the jetting channels. The driver circuit receives a drive waveform comprising non-jetting pulses and jetting pulses, and gating signals comprising a first active gating signal designated for jetting the first print fluid, and a second active gating signal designated for jetting the second print fluid. The driver circuit selectively applies the non-jetting pulses and the jetting pulses to actuators of the first jetting channels based on the first active gating signal to jet the first print fluid, and selectively applies the jetting pulses to actuators of the second jetting channels based on the second active gating signal to jet the second print fluid.
