摘要:
An inkjet recording apparatus suppresses defective ejection while reducing a consumed ink amount. In the apparatus, a cap-open period, during which a cap member does not cap ejection ports of a recording head of the apparatus, is measured, and a recovery operation executed by a recovery unit is controlled based on a cumulated cap-open period. With the above arrangement, there can be solved a problem that the ink ejecting state of the recording head is deteriorated depending on a recording operation because a cap-open state, in which the cap member does not cap the ejection ports of the recording head, continues while the inkjet recording apparatus executes the recording operation, thereby the reliability of the inkjet recording apparatus can be improved.
