ABSTRACT:
An ink jet assembly comprises a magnetic driver and a liquid droplet instrument. The driver includes a plurality of magnets, which may be selectively energized. The instrument includes a diaphragm means, which forms an outer wall of each of a plurality of chambers and when exposed to a magnetic field, deforms to decrease the volume of a chamber to increase the pressure therein to express a liquid droplet therefrom. The driver and instrument are releasably secured to each other to permit replacement of the instrument without disposing the driver.
