Zusammenfassung:PROBLEM TO BE SOLVED: To improve accuracy of a dot recording position at low cost.SOLUTION: A conveyance control unit 45 for performing conveyance control of a Y bar 34 on which an inkjet head 32 is mounted in a sub-scanning direction F obtains a control conveyance amount in the sub-scanning direction F of the Y bar 34 specified based on the conveyance schedule of the Y bar 34 and the resolution of an encoder 39 and a theoretical conveyance amount in the sub-scanning direction F of the Y bar 34 specified based on recording resolution and a nozzle pitch, to obtain an accumulated error obtained by accumulating and adding the error of the control conveyance amount with respect to the theoretical conveyance amount by 16 passes. When the accumulated error is larger than a minimum conveyance amount specified based on the resolution of the encoder 39, the accumulated error is corrected by the control conveyance amount of one or a plurality of passes in each minimum conveyance amount, to convey the Y bar 34 in the sub-scanning direction F.
