  • Publication number: 20140240761
    Abstract: A communicator is configured to perform communication with a server. An image processor is configured to perform image processing. When executed by a processor, the instructions stored in a memory cause the processor to perform: a login process of establishing a login state that allows execution of a specific job that causes the image processor to perform image processing and that causes the communicator to perform communication with the server; a sign-in process of establishing a sign-in state that allows use of the server; a job execution process of executing the specific job on condition that a current state is the login state and the sign-in state; and a cancel process of cancelling the login state and of cancelling the sign-in state when a logout condition for cancelling the login state is satisfied in a state where the sign-in state is not cancelled.
