  • Publication number: 20210197589
    Abstract: A printing apparatus includes a printing unit that performs printing on a printing medium, a transporting belt that transports the printing medium and has an endless shape, and a belt-driving roller that causes the transporting belt to circulate and has a cylindrical shape. In the transporting belt, a magnetic scale having a magnetic pole changing at a predetermined pitch is arranged along a transport direction of the printing medium. The belt-driving roller includes an outer circumferential surface constituted of a magnet body, and is in contact with the transporting belt at the outer circumferential surface. The circumferential length of the outer circumferential surface of the belt-driving roller is an integer multiple of the pitch of the magnetic scale.

  • Patent number: 11027563
    Abstract: Provided is a printing apparatus that includes a printing unit, a conveyance belt that is stretched over a first roller and a second roller such that a tension is applied to the conveyance belt, and a control unit configured to perform on the conveyance belt a forward rotation operation configured to convey a medium in a conveyance direction and a reverse rotation operation configured to convey the medium in a reverse conveyance direction. When the reverse rotation operation has been performed during a print pause period and the tension at the end of the print pause period has changed from the tension when printing of a first image is complete due to the reverse rotation operation performed during the print pause period, the control unit corrects a rotation amount of the conveyance belt in a first rotation direction during printing of a second image.
