The continuous ink jet is broken into drops inside the chamber using a pulse from a piezoelectric crystal. Up to 120,000 of these tiny droplets are expelled every second, each just half the diameter of a human hair.
Droplets that are required for printing are charged by an electrode as they break off from the ink jet, and to avoid waste, the printer re-circulates the unused ink droplets.
