Abstract

A nozzle arrangement for an inkjet printhead includes a substrate that incorporates drive circuitry and defines an ink inlet channel. At least one wall extends from the substrate. A roof is fast with the at least one wall and defines an ink ejection port which is in fluid communication with an ink chamber defined by the roof, the at least one wall and the substrate, the ink chamber being in fluid communication with the ink inlet channel. An ink ejection member is interposed between the ink inlet channel and the ink ejection port such that reciprocal movement of the ink ejection member causes ejection of ink from the ink ejection port. An actuator is connected to the drive circuitry at a fixed end and is configured so that a free end is displaced reciprocally with respect to the substrate on receipt of an electrical signal by the actuator from the drive circuitry. A movement transfer mechanism is interposed between the free end of the actuator and the ink ejection member such that reciprocal movement of the free end is transferred to the ink ejection member.
