Abstract: A printer includes a glue belt on which a plurality of different types of media are arranged, an ejection head that ejects ink to the plurality of media while reciprocating along an X-axis direction, a first detection unit that detects an end portion of the medium, a second detection unit that detects a thickness of the medium, and a control unit, and the control unit causes the first detection unit to detect an end portion of each of the plurality of media, sets an ejection range in which the ink is ejected for each medium based on a detection result of the first detection unit, causes the second detection unit to detect a thickness of each of the plurality of media, and determines an adjustment amount for adjusting the landing position of the ink for each medium based on a detection result of the second detection unit, and adjusts the landing position based on the adjustment amount and causes the ink to be ejected in the ejection ranges of the plurality of media from the ejection head.

Abstract: A recording device includes a recorder, a placement portion, an adjustment mechanism, a movement mechanism, a medium detector, an input portion, a notification portion, and storage. The recorder performs a positional information notification operation of causing the notification portion to notify positional information of the placement portion in a first direction based on identification information of a medium input by the input portion and correspondence information stored in the storage, and a detection result notification operation including moving the placement portion so that an entire region in the second direction of the placement portion passes through a detection position, causing the medium detector to detect whether the medium is located at a reference position during when the medium is passing through the detection position, and causing the notification portion to notify information based on a result of the detection by the medium detector.

Abstract: A printing apparatus includes an image formation unit, a tray on which a medium is placed, a movement unit, and a control unit. The image formation unit includes a first head forming a first image and a second head forming a second image. The movement unit is provided so as to be capable of moving the tray to a first position at which the medium is placed and a second position serving as a reference position. The control unit switches between a first mode and a second mode. In the first mode, a starting position is moved to an image forming region, and the tray is not moved to the second position, and a movement direction is changed to form the first image and the second image. In the second mode, after the first image is formed, the tray is moved to the second position, and then the movement direction is changed to form the second image.
