Abstract:
1. A method of manufacturing a liquid ejection apparatus, the liquid ejection apparatus comprising: at least one liquid ejection head comprising: a plurality of ejection-opening groups each constituted by a plurality of ejection openings for ejecting liquid; and a plurality of ejection-passage groups respectively corresponding to the plurality of ejection-opening groups and each constituted by a plurality of ejection passages respectively extending to the plurality of ejection openings of a corresponding one of the plurality of ejection-opening groups; a plurality of caps provided respectively for the plurality of ejection-opening groups and formed respectively with a plurality of recesses each for covering the plurality of ejection openings of a corresponding one of the plurality of ejection-opening groups; a moving device configured to move the plurality of caps relative to the at least one liquid ejection head to a capping position at which each of the plurality of recesses covers a corresponding one of the plurality of ejection-opening groups and an uncapping position at which each of the plurality of caps is spaced apart from a corresponding one of the plurality of ejection opening groups; a plurality of suction passages respectively communicating with the plurality of recesses respectively formed in the plurality of caps; at least one sucking device configured to suck fluid through the plurality of suction passages from the plurality of recesses respectively formed in the plurality of caps; a controller configured to control the moving device to move each of the plurality of caps selectively to one of the capping position and the uncapping position and control the at least one sucking device such that when each of at least one of the plurality of caps is located at the capping position, a corresponding at least one of the at least one sucking device sucks the fluid from at least one of the plurality of recesses which corresponds to the at least one of the plurality of caps, the method comprising:
