Abstract
An ink jet recording apparatus for projecting ink onto a recording medium. The apparatus includes an ink jet head adapted to receive ink having an ejection nozzle for ejecting ink towards said recording medium. An ink tank means stores ink and supplies the stored ink to the ink jet head. A switching mechanism selectively switches between a first condition where the ink tank is in fluid communication with the ink jet head and a second condition where the ink jet head is vented to atmosphere. A nozzle cap selectively covers the ejection nozzle. A suction mechanism creates a suction in the cap. The cap draws ink and air out of the ink jet head through the ejection nozzle to prevent clogging and remove air bubbles from the ink.
