ABSTRACT:
An inkjet printhead comprising a plurality of micro-electromechanical ink ejection nozzles is provided. Each nozzle comprises a nozzle chamber positioned on a substrate, and actuators and associated coupling structures for ejecting ink from the chamber. The nozzle chamber has a static nozzle section and an active nozzle section. The static section has static walls extending from the substrate and the active section has a roof wall defining an ink ejection port and an active wall depending from the roof wall about the static walls. The roof and active walls are displaceable relative to the static walls so as to change a volume of the chamber. This causes ink in the chamber to be ejected from the port. The actuators are arranged to displace the roof and active walls with substantially rectilinear movement, via the coupling structures, on receipt of an actuating signal from drive circuitry on the substrate.
