Abstract
An embodiment relates generally to a method of ejecting ink. The method includes providing a continuous stream of ink from a pressurized fluid chamber and activating a drive signal to activate a micro-electrostatic mechanical system (MEMS) membrane. The method also includes stably breaking up the jet stream into uniform droplets in response to deflecting the MEMS membrane to perturb the continuous stream of ink.
