A recording device comprising: a support unit that includes a support surface that supports a medium (P); and a recording unit , which is capable of moving relatively in a direction (X) that runs along the support surface with respect to the medium that is supported on the support unit, and which performs a recording operation on the medium from a recording head , characterised in that the support unit includes a first power source , and a support control unit that controls operation of the support unit on the basis of power that is supplied from the first power source, the recording unit includes a second power source , and a recording control unit that controls operation of the recording unit on the basis of power that is supplied from the second power source, wherein the support control unit and the recording control unit are capable of executing a reset operation that returns respective operational states to an initial state, in a case in which one control unit of the support control unit and the recording control unit has initiated the reset operation, the corresponding control unit transmits a reset initiation signal, which initiates the reset operation after causing an operational state save operation to be performed, to the other control unit, wherein the support control unit and the recording control unit are capable of mutually transmitting a reset completion signal in a case in which the respective reset operations have been completed, and each control unit determines whether or not the reset operation of both control units has been completed on the basis of whether or not the reset completion signal has been transmitted from a partner control unit in a state in which a self-reset operation has been completed. a support unit that includes a support surface that supports a medium (P); and a recording unit , which is capable of moving relatively in a direction (X) that runs along the support surface with respect to the medium that is supported on the support unit, and which performs a recording operation on the medium from a recording head , characterised in that the support unit includes a first power source , and a support control unit that controls operation of the support unit on the basis of power that is supplied from the first power source, the recording unit includes a second power source , and a recording control unit that controls operation of the recording unit on the basis of power that is supplied from the second power source, wherein the support control unit and the recording control unit are capable of executing a reset operation that returns respective operational states to an initial state, in a case in which one control unit of the support control unit and the recording control unit has initiated the reset operation, the corresponding control unit transmits a reset initiation signal, which initiates the reset operation after causing an operational state save operation to be performed, to the other control unit, wherein the support control unit and the recording control unit are capable of mutually transmitting a reset completion signal in a case in which the respective reset operations have been completed, and each control unit determines whether or not the reset operation of both control units has been completed on the basis of whether or not the reset completion signal has been transmitted from a partner control unit in a state in which a self-reset operation has been completed. <EOS>
