Abstract: A recording device includes a recording unit configured to perform recording on a medium, a transporting belt configured to transport the medium, the transporting belt including a surface on which the medium is able to be supported, a washing unit configured to wash the surface using a liquid, an ultrasonic sensor configured to transmit an ultrasonic wave onto the surface and receive the ultrasonic wave reflected from the surface, and a control unit configured to determine a remaining state of the liquid on the surface based on a result of detection by the ultrasonic sensor, in which the ultrasonic sensor transmits the ultrasonic wave onto at least part of the transporting belt, from downstream of the washing unit to upstream of the recording unit, in a rotation direction of the transporting belt.
