An inkjet printer has a plurality of ink ejection nozzles. Each nozzle includes a paddle ( 5 ) located in a chamber ( 2 ) which is moveable in a forward direction between a rest state and an ejection state, for ejecting fluid from the chamber through an outlet port ( 11 ) as it moves from the rest state to the ejection state. The paddle ( 5 ) is positioned to substantially close an inlet port ( 3 ) when in the rest state and the paddle ( 5 ) and the inlet port ( 3 ) define an aperture ( 16 ) between themselves. The paddle ( 5 ) includes means ( 12 ) to reduce fluid flow through the aperture ( 16 ) toward the inlet port ( 3 ) as the paddle ( 5 ) moves from the rest state to the ejection state.
