ABSTRACT:
Apparatus and method for periodically applying liquid solvent to the outer surface of a nozzle plate of an ink jet nozzle to clean ink jet nozzle openings at the nozzle plate outer surface. Flow of the liquid solvent along the nozzle plate outer surface is under the influence of gravity. Energization of piezoelectric crystals to vibrate the ink jet nozzle promotes liquid solvent flow.
