Claims17
An ink jet recording apparatus which discharges ink from a discharge port provided in the discharge port surface of recording means comprising:
- a cap closely contacting said discharge port and covering said discharge port;
- sucking means for sucking ink from said discharge port through said cap closely contacted said discharge port;
- gap forming means for partially generating a gap between said cap and said discharge port surface;
- a communication valve for communicating the inside of said cap with atmosphere.
A recovery method of the ink jet recording apparatus which discharges ink from a discharge port provided on the discharge port surface of recording means comprising:
- a sucking step of sucking ink from said discharge port by sucking means in a state of the cap closely contacting said discharge port surface;
- a first expelling step of generating a gap between said cap and said discharge port surface and expelling ink inside said cap by said sucking means;
- and
- a second expelling step of closely contacting said cap on said discharge port surface with a communication valve for communicating the inside of said cap with an atmosphere put into a communication state and expelling ink inside said cap by said sucking means.
