Abstract

A droplet generator assembly is used for an ink jet printhead of a continuous ink jet printer. A nozzle plate (2) has associated nozzles to stimulate jets. The droplet generator assembly has a fluid ingress location (8) and a fluid egress location (9), on a side of the resonator body opposite the nozzle plate (2). A fluid trench (5) redirects flow in-line with the nozzles. A fluid passage (4) extends from the fluid ingress location (8) to the fluid trench (5).
