First Claim
Patent Images
1. An eject recovery method comprising steps of:
- a first step for performing suction from a first eject port for ejecting first ink and a second eject port for ejecting second ink different from the first ink through a cap for capping said first eject port and said second eject port while said cap is capping said first eject port and said second eject port collectively; and
a second step for communicating an inside of said cap to atmosphere while said cap is capping said first eject port and said second eject port, and then performing suction from said cap while the inside of said cap communicates to atmosphere and while said cap is capping said first eject port and said second eject port, and concurrently ejecting ink into said cap from said first eject port and said second eject port.

6. An ink-jet recording apparatus comprising:
-
a cap for capping a first eject port for ejecting first ink and a second eject port for ejecting second ink different from said first ink collectively, and equipped with a communicating valve to atmosphere;
a sucking means for performing suction while said cap is capping said ink eject ports; and
a control means for causing said sucking means to perform suction from said first eject port and said second eject port through said cap while said cap is capping said first eject port and said second eject port collectively, then causing said valve to communicate an inside of said cap to atmosphere while said cap is capping said first eject port and said second eject port, and thereafter causing said sucking means to perform suction from said cap while the inside of said cap communicates to atmosphere and while said cap is capping said first eject port and said second eject port and concurrently ejecting ink into said cap from said first eject port and said second eject port. - View Dependent Claims (7, 8, 9, 10)
