Abstract
An ink jet recording apparatus includes a die reservoir and at least one ink channel in communication with the die reservoir. The method and apparatus contemplate heating ink in the die reservoir to increase vapor pressure of the ink to cause mass transfer of water vapor molecules across an interface between the air bubble and the ink and removing air bubbles entrapped within the die reservoir and the ink channel. An ink jet recording apparatus may also include a heat sink provided to the die reservoir to cool the die reservoir below predetermined threshold temperatures. The heat sink may be fixably attached to either a carriage or maintenance station of the ink jet recording apparatus, or the heat sink may be integrally formed with the die reservoir and the ink channel as part of the replacement cartridge.
