摘要： PROBLEM TO BE SOLVED: To provide a recording device that can reduce fluctuation in a conveyance amount in a sub-scanning direction by a conveying roller without moving a recording head and a detection means.
SOLUTION: Under a condition that the movement of a carriage (5) having mounted thereon the recording head (6) and the rotation of a conveyance roller (15) are stopped, a plurality of marks (101) are printed on a recording medium (16) in the sub-scanning direction by means of a nozzle row of the recording head (6). Next, a correction amount for correcting a conveyance amount of the conveyance roller (15) is calculated out on the basis of a relationship between an actual conveyance amount of the recording medium (16) at a predetermined rotational position of the conveyance roller obtained in such a manner that the marks (101) are detected by the detection means (a reading sensor 30) under a condition that the conveyance roller (15) is rotated and a theoretical conveyance amount of the recording medium (16) at a predetermined rotational position. The conveyance amount of the conveyance roller (15) is controlled by using the correction amount.
