ABSTRACT:
A nozzle arrangement is provided for an inkjet printer. The nozzle arrangement includes a substrate assembly defining an outlet port through which ink can be ejected. A retainer is mounted to the substrate assembly and defines an internal coil chamber in which a coil is retained. A plunger assembly is engaged with the retainer to form an ink chamber in fluid communication with the outlet port. The plunger assembly includes a plunger that is able to move toward the outlet port and reduce the volume of the ink chamber. Drive and control circuitry is electrically coupled to the coil, and is configured to energize the coil and cause the plunger to move toward the outlet port so that ink is ejected from the outlet port.
