Abstract: An ink jet print head has at least one nozzle for ejecting ink droplets and includes an adjacent chamber containing liquid ink solvent therein. An absorbent material member is positioned to have one end thereof in the chamber-containing solvent and is directed or trained to an area which is in front of or around the nozzle to carry fluid or vapor therearound for the purpose of providing a moist or humid atmosphere at the nozzle and thereby prevent drying of the ink.

Abstract: An actuator, which in a preferred embodiment, is shown in a wire matrix printer, and includes a magnetic structure having a support member associated therewith. When used in a wire matrix printer, the actuator includes a plurality of output members (in disc form) mounted on said support member for movement between operative and inoperative positions. Each output member has a coil structure thereon, and when the coil structure is energized, the associated output member is moved to the operative position where a printing element on the output member is brought into printing relationship with a platen of the printer.
