ABSTRACT:
An ink ejection arrangement for an inkjet printhead is provided. The arrangement comprises an ink chamber, a nozzle and an ink ejector. The ink chamber is arranged in fluid communication with an ink supply channel via an aperture so as to supply ink to the nozzle, with the ink ejector arranged within the aperture. The ink ejector is operable to cause ejection of ink from the nozzle and resupply of ink to the ink chamber from the ink supply channel, and incorporates a movable paddle having a non-planar profile configured to control the flow of ink between the ink chamber and the ink supply channel during ejection and resupply.
