Ink jet printing apparatus, and print head recovery device and print head recovery method

A print head recovery processing device for performing a recovery process for a print head capable of ejecting ink from ejection ports, comprising:

• a cap configured to cover the ejection ports;
• a suction unit configured to draw ink from the ejection ports into an interior of the cap by applying a suction force to the interior of the cap that is covering the ejection ports;
• an atmosphere communication unit configured to expose to the atmosphere the interior of the cap that is covering the ejection ports;
• a pressure increase unit configured to increase a pressure in an internal of the print head;
• and
• a control unit configured to permit the suction unit to apply the suction force to the interior of the cap, and to permit the pressure increase unit to increase the pressure in the internal of the print head before the atmosphere communication unit exposes the interior of the cap to the atmosphere in a state where the ejection ports is covered with the cap.

A print head recovery processing method for performing a recovery process for a print head capable of ejecting ink from ejection ports, comprising:

• a covering step of covering the ejection ports with a cap;
• a drawing step of drawing ink from the ejection ports into an interior of the cap by applying a suction force to the interior of the cap that is covering the ejection ports;
• an exposing step of exposing to the atmosphere the interior of the cap that is covering the ejection ports;
• and
• an increasing step of increasing a pressure in an internal of the print head,
• wherein, in a state where the ejection ports are covered with the cap, applying the suction force to the interior of the cap at the drawing step and increasing the pressure in the internal of the print head at the increasing step are performed before exposing the interior of the cap to the atmosphere at the exposing step is performed.
