摘要： A scanner of the present invention includes a transport section configured to transport a transport medium and a control section configured to carry out feedback control on the transport section according to a transport state of the transport medium. The control section is further configured to reduce a gain in the feedback control in a case where the transport medium is transported in a first region where a load on the transport medium varies compared to a case where the transport medium is transported in a second region which is on an upstream side of the first region or in a third region which is on a downstream side of the first region.

摘要： A recording apparatus includes a cassette or a feeding tray that is configured to mount a medium thereon, a transport unit that transports the medium mounted on the cassette or the feeding tray, and a recording head that performs recording on the medium. Furthermore, the recording apparatus includes a medium detection device and a deviation amount acquisition section. The medium detection device detects at least one of both side edges in a width direction intersecting a transport direction of the medium that is transported from the cassette or the feeding tray (step S12). The deviation amount acquisition section acquires a deviation amount of the recording head in the width direction of the medium based on at least one side edge detection position detected by the medium detection device (step S13).

摘要： A control unit causes a carriage to move in a width direction under a first movement control of changing a location of the carriage with a first resolution so that a sensor located forward in movement detects an edge of a medium. Thereafter, the first movement control is switched to a second movement control of changing the location of the carriage with a second resolution higher than the first resolution and the carriage is caused to move in the width direction so that a sensor located rearward in movement detects the edge.
