Inkjet printer with electro-magnetically actuated ink plunger

摘要

An inkjet printing nozzle arrangement comprising: (a) a nozzle chamber having an ink ejection port at one end; (b) a plunger constructed from soft magnetic material and positioned between said nozzle chamber and an ink chamber, said ink chamber allowing for the supply of ink to said nozzle chamber; (c) an electric coil located adjacent to the plunger and electrically connected to a nozzle activation signal wherein upon activation of the activation signal, said plunger is caused by said coil to move from an ink loaded position to an ink ejection position thereby causing the ejection of ink from said ink ejection port. <IMAGE>
