Abstract:
The present invention relates to a printhead for an inkjet printer. The printhead includes a plurality of nozzle arrangements. Each nozzle arrangement includes a nozzle defining a nozzle chamber in fluid communication with an ink ejection port. A static coil is fixed within the chamber. A movable coil is movably attached within the chamber. An actuator is configured to provide current to the coils so that the movable coil reciprocates relative to the static coil and ink in the chamber is ejected from the ink ejection port.
