    摘要： A sheet suction device includes a drum including multiple suction holes in a circumferential surface of the drum, the drum configured to bear a sheet on the circumferential surface and rotate, a suction device configured to suck the sheet through the multiple suction holes, a rotary valve between the multiple suction holes of the drum and the suction device, the rotary valve configured to rotate relative to the drum to change a number of the multiple suction holes communicating with the suction device, and a driver configured to relatively rotate the drum and the rotary valve.

    摘要： A sheet suction device includes a bearing member configured to bear a sheet on a circumferential surface of the bearing member and rotate in a first direction, a plurality of suction holes in a bearing region in the circumferential surface of the bearing member, a suction device connected to the plurality of suction holes, the suction device configured to suck the sheet through the plurality of suction holes, and a first member between the plurality of suction holes and the suction device, the first member rotatable in a second direction different from the first direction to change a suction region of the suction device connected to the plurality of suction holes. A rotation of the first member in the second direction expands the suction region of the suction device in the bearing region of the bearing member.

    摘要： An image forming system includes a transport section that includes a support surface supporting a sheet-like medium and transports the medium while supporting the medium on the support surface, a first pressure generating section that generates pressure used to suck the medium supported on the support surface, and an image forming section that forms an image on the medium transported by the transport section. First suction holes that communicate with the first pressure generating section, first protrusions, and sealed portions that are disposed at positions where end portions of the medium in the medium width direction are supported and restrict inflow of air to regions, in which the first suction holes are arranged, from the outside of the end portions of the medium in the medium width direction are arranged on the support surface in a medium support region where the medium can be supported.

    摘要： A printing apparatus and a printing method that allow transport performance, and reading and correction performance to be compatible with each other are provided. The above problem is solved by a printing apparatus including a suction unit that suctions a recording medium with a first suction force on a supporting surface; a correction unit that corrects at least one of a printing unit or a reading unit on the basis of a reading result of the reading unit; and a controller that controls a suction force of the suction unit at a reading position of the reading unit and that suctions the recording medium on the suction unit with a second suction force smaller than the first suction force or stops suction of the suction unit, at least in a case where the reading unit reads an image using a reading result in the correction unit.
