Abstract:
Provided that at least one of a plurality of recording media which are successively conveyed by a conveyance mechanism is a reference recording medium, a liquid ejection apparatus determines, for an ejection surface, an ejection region which opposes a recording region on the reference recording medium when the medium is being conveyed and a non-ejection region which does not oppose the recording region. Both of the ejection openings in the ejection region and the ejection openings in the non-ejection region carry out at least one of preliminary ejection and preliminary vibration in a recovery period. An amount of ejection of liquid in the preliminary ejection and the frequency of vibration of meniscus in the preliminary vibration are larger in the ejection openings in the ejection region than in the ejection openings in the non-ejection region.
