Abstract
An apparatus for removing foam from an ink container of a printer including a nozzle disposed within the ink container such that the nozzle floats upon a surface of the ink located within the container. The nozzle contains a plurality of inlet channels located therein and an outlet communicating with the inlet channels. A vacuum source is coupled with the outlet of the nozzle to create a suction force within the inlet channels of the nozzle to remove foam located on the surface of the ink. As the level of the ink is depleted or added to the container, the nozzle remains on the surface of the ink and the foam is actively removed from the surface through the inlet channels.
