摘要： When paper dirt that could not be removed completely by the wiping gets trapped in the recessed portions formed in the ejection port face, the paper dirt may interfere with ejection ports, giving rise to a possibility of image impairments. To deal with this problem, the ejection ports and the recessed portions in the print head are shifted from each other so that their positions are not aligned in the wiping direction.
