Abstract (en)

An ink jet nozzle arrangement having an ink ejection port for the ejection of ink said nozzle comprising: a nozzle chamber interconnected to said ink ejection port and having one moveable wall including an electromagnetic coil, said nozzle chamber being in a magnetic field such that, upon activation of said electromagnetic coil, said moveable wall experiences a lorenz force and is caused to move so as to result in the ejection of ink from said nozzle chamber via said ink ejection port. <IMAGE>
