Abstract
A recovery device for an ink jet recording apparatus having a cup for an ink discharge port of a recording head and a suction device communicating with the cap for sucking ink from the ink discharge port includes a communicating tube, a communicating valve, and a ventilating valve. The communication tube communicates with the cap and a subtank which supplies ink to the recording head. A communicating valve connects and disconnects communication of the cap with the subtank and is provided in an intermediate portion of the tube. A ventilating valve communicates the interior of the tube with the atmosphere and is provided separately from the communicating valve.
