Abstract: A printing system includes a discharging unit, a mounting unit, a post-process unit, a relay unit, and a control unit. The discharging unit discharges sheets. The mounting unit is provided to an apparatus body, and sheets are mounted on the mounting unit. The post-process unit performs a post-process on sheets. The relay unit is provided to the apparatus body, is configured to transport sheets to the post-process unit, and includes a lower path member. The lower path member is configured to be switched between a first state in which the lower path member serves as part of a relay path from the discharging unit to the post-process unit and a second state in which the lower path member opens the relay path. The control unit, when the lower path member is in the second state, makes sheets be discharged from the discharging unit to the mounting unit.

Abstract: A recording system includes a transportation unit that transports a paper sheet, an ejection unit that ejects an ink, a heating unit that heats the paper sheet, a discharge unit to which the paper sheet is discharged, and a control unit. The control unit specifies an amount of ejection of the ink from the ejection unit. The control unit also controls an operation of the heating unit such that an undried region where the ink on the paper sheet is not dried and a dried region where the ink on the paper sheet is dried are formed on the paper sheet. Then, the control unit controls a transporting operation by the transportation unit such that the paper sheet on which the dried region and the undried region are formed is discharged to the discharge unit.

Abstract: A medium transport device includes a first roller that transports a medium in a transport direction, and a control unit that controls the first roller. The control unit rotates the first roller at a first speed when the first roller transports a first medium. When a rear end of the first medium is located downstream of the first roller in the transport direction and a leading end of a second medium transported subsequently to the first medium is located upstream of the first roller in the transport direction, the control unit can perform a deceleration control of decelerating the first roller to a second speed slower than the first speed.
