To improve the conveying accuracy of a Y-bar, thus improving printed image quality. A drive mechanism 40 (a drive motor 44a and a drive motor 44b) for conveying a Y-bar 30 in an X axis direction and linear scales 50a and 50b are provided on a flatbed 10 on which a medium is mounted and fixed, and a head unit drive mechanism 33 (a drive motor 37) that conveys a head unit 20 in a Y axis direction and optical linear encoders 51a and 51b that detect the linear scales 50a and 50b are provided on the Y-bar 30, on which the head unit 20 is mounted. Then, a controller 60 carries out a print control by controlling the head unit 20, the drive motor 37, the drive motor 44a, and the drive motor 44b, and furthermore, corrects controlled variables of the drive motor 44a and drive motor 44b based on results of measurements by the optical linear encoder 51a and optical linear encoder 51b. |
