Latest Patents

One of Sousa's latest patents is titled "Head tending method and apparatus for an ink jet printer." This invention describes a head tending apparatus designed for an inkjet printing system. The apparatus includes a solvent supply system that sprays solvent on the faces of the ink jets and in the jet openings. Additionally, it features a brush that scrubs the ink jet faces during and immediately after the spraying process. The solvent vapors enter the jets and help to deprime them, allowing any remaining ink to drain back to the ink reservoir. This process ensures that when the jets are next primed with ink, they are substantially free of air bubbles. Head tending is typically performed when the printer is shut down or prior to the priming of the ink jets.

Another patent by Sousa is also titled "Head tending apparatus for an ink jet printer." This invention similarly focuses on improving the maintenance of ink jets in a printing system. The apparatus includes a solvent supply system and a brush for cleaning the ink jet faces. The solvent loosens and dissolves any solid matter that may have formed on the jet faces or in the jet openings. The brush then cleans the loosened matter off the jet faces, ensuring optimal performance of the printer.
