Printing apparatus and medium conveyance method

A medium conveyance method in a printing apparatus including

• a printing unit configured to print an image on a medium conveyed in a conveyance direction,
• a first roller arranged upstream of the printing unit in the conveyance direction,
• a second roller arranged downstream of the printing unit in the conveyance direction, and
• a conveyance belt that is stretched over the first roller and the second roller such that a tension is applied to the conveyance belt between the first roller and the second roller and that is configured to support the medium at least in a facing region facing the printing unit, the printing apparatus being configured to perform on the conveyance belt a forward rotation operation configured to convey the medium supported by the conveyance belt in the conveyance direction by causing the conveyance belt to be rotated in a first rotation direction, and a reverse rotation operation configured to convey the medium supported by the conveyance belt in a reverse conveyance direction, which is an opposite direction to the conveyance direction, by causing the conveyance belt to be rotated in a second rotation direction, which is an opposite direction to the first rotation direction, the medium conveyance method comprising:
• correcting a rotation amount of the conveyance belt in the first rotation direction during printing of a second image, when the reverse rotation operation has been performed during a print pause period, which is a period after printing of a first image and prior to printing of the second image, and the tension of the conveyance belt has changed as a result of the reverse rotation operation, wherein the corrected rotation amount corresponds to a change in tension of the conveyance belt.
