An inkjet head adjustment method whereby inkjet heads can be automatically adjusted after replacement of a head module. During adjustment after replacement of a head module in an inkjet head (56) having a plurality of head modules (200) arranged in the X direction: the relative displacement in the Y direction of each head module after replacement is measured; a readjustment value for droplet ejection timing for the replaced head module is calculated on the basis of the measured displacements in the Y direction; a correction value for droplet ejection timing is calculated for head modules that have not been replaced, excluding a head module serving as a reference for &Dgr;Y&thetas;z adjustment; the adjustment value for droplet ejection timing for the replaced head module and the correction value for head modules not replaced or an adjustment value for droplet ejection timing after correction are stored; and adjustment after head module replacement is automatically executed. |
