Patent ID: 7762648

Claim:
A liquid ejection apparatus comprising: a liquid ejection head which comprises nozzles including at least one suctioned nozzle and at least one non-suctioned nozzle and ejecting liquid, pressure chambers supplying the nozzles with the liquid, and a common liquid chamber supplying the pressure chambers with the liquid; and an individual suctioning unit which suctions the liquid in the at least one suctioned nozzle, wherein when the individual suctioning unit suctions the liquid in the at least one suctioned nozzle, a following inequality is satisfied: P 0 −ΔP in< Pn, where Pn is an internal pressure of the at least one non-suctioned nozzle of which the liquid is not suctioned by the individual suctioning unit, and P 0 −ΔPin is a first limit value of the internal pressure of the at least one non-suctioned nozzle above which air does not flow into the at least one non-suctioned nozzle.
