Abstract

See full text

The liquid ejection apparatus includes a circulation unit configured to circulate a liquid along a circulation passage extending from a liquid supply source to the liquid supply source through a liquid ejection head. Further, the liquid ejection apparatus includes a deaeration unit configured to perform a deaeration operation of decreasing a dissolved gas amount of the liquid, a recovery unit configured to recover ejection performance of an ejection opening, and a control unit configured to control an operation of driving the circulation unit and the deaeration unit. The control unit starts the deaeration operation and circulates the liquid having been deaerated by the deaeration operation inside a circulation path after the recovery operation and before an initial printing operation after the recovery operation.
