    摘要: Provided is a transport device including a feeding unit on which a roll-type medium is set and which feeds the medium by rotating the medium, and an endless transport belt that transports the medium in a transport direction by supporting the medium fed out from the feeding unit and rotating. When seen from a support direction in which the transport belt supports the medium, the feeding unit is configured to change the posture thereof so as to incline a rotating shaft of the medium with respect to a width direction that is a direction intersecting the transport direction.

    摘要: 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.

    摘要: A printing apparatus includes a recording section including a plurality of ink heads configured to discharge, ink, a first reaction solution head, and a second reaction solution head configured to discharge the reaction solution, a driving section configured to drive the recording section, and a controller configured to execute causing the driving section to move the recording section in a first direction, causing the plurality of ink heads to discharge the ink, and causing the first reaction solution head and the second reaction solution head to discharge the reaction solution. The plurality of ink heads are arranged in the first direction. The first reaction solution head is located downstream in the first direction of an ink head located most downstream in the first direction. The second reaction solution head is located between two ink heads located adjacent to each other in the first direction.

    摘要: 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.
