ABSTRACT:
A cleaning station for a vertical nozzle plate of an ink jet printer includes a cylindrical cleaning roller that has an outer surface, and has a substantially vertical central axis and a substantially vertical rotational axis. The roller is spaced from the nozzle plate to form a cleaning cavity between the roller and the nozzle plate. The roller has a top end above the nozzle plate and a bottom end below the nozzle plate. A drive element is connected to the roller to rotate the roller about its rotation axis. A fluid outlet near the top of the roller directs cleaning fluid onto the outer surface of the roller, and into the cleaning cavity between the roller and the nozzle plate. A fluid reservoir stores cleaning fluid, and a fluid conduit conducts cleaning fluid from the fluid reservoir to the fluid outlet.
