ABSTRACT:
Provided is a nozzle arrangement for an ink jet printer. The arrangement includes a wafer substrate with a layer of drive circuitry, said substrate defining an ink supply channel through the substrate leading to an ink chamber with a roof defining an ink ejection port. The arrangement also includes an ink ejection arrangement for ejecting ink from the ink chamber via the port, said ink ejection arrangement having four symmetrically arranged thermal bend actuators each connected to a respective side to ensure that the roof is operatively displaced in a rectilinear manner during ink ejection.
