Solenoid actuated magnetic plate ink jet printing mechanism

Abstract

An ink jet printhead for the ejection of ink from an ink ejection nozzle includes: a substrate; a conductive coil formed on the substrate and operable in a controlled manner, a moveable magnetic actuator surrounding the conductive coil and forming an ink nozzle chamber between the substrate an, the actuator, the moveable magnetic actuator further including an ink ejection nozzle defined therein; wherein variations in the energization level of the conductive coil cause the magnetic actuator to move from a first position to a second position, thereby causing a consequential ejection of ink from the nozzle chamber as a result of fluctuations in the ink pressure within the nozzle chamber. The arrangement can further include an ink supply channel interconnecting the nozzle chamber supplying ink to the nozzle chamber. The interconnection can include a series of elongated slots etched in the substrate. The substrate can include a silicon wafer and the ink supply channel can be etched through the wafer.
