ABSTRACT:
An inkjet printhead is provided comprising ink ejection nozzles arranged to eject ink from respective ink chambers onto media through respective apertures of the ink chambers and respective passages spaced from the apertures, and a fluid director arranged to direct a fluid into the space between the apertures and passages so as to pass through the passages. The fluid director is configured to direct the fluid into the space so that a fluid pressure within the space is less than a fluid pressure within the space without the fluid.
