System and image forming device

A system comprising an image forming device, a first information processing device, and a second information processing device,

• wherein the first information processing device, the second information processing device, and the image forming device is connected to the Internet,
• the image forming device is configured to execute an image upload process of uploading, to the cloud storage, first image data indicating a first remote operation screen,
• the first information processing device is configured to execute a screen display process of downloading the first image data from the cloud storage to cause the user interface of the first information processing device to display the first remote operation screen indicated in the first image data,
• in a case where an operation on the first remote operation screen is received via the user interface of the first information processing device, the first information processing device is configured to execute an operation upload process of uploading, to the cloud storage, first operation data indicating an operation content,
• the image forming device is configured to download the first operation data from the cloud storage and execute a process corresponding to an operation indicated by the first operation data,
• the image forming device is configured to execute an image transmission process of transmitting second image data indicating a second remote operation screen to the second information processing device, not via the cloud storage,
• in a case where the second information processing device receives the second image data, the second information processing device is configured to execute a local screen display process of causing the user interface of the second information processing device to display the second remote operation screen indicated by the received second image data,
• in a case where an operation on the second remote operation screen is received via the user interface of the second information processing device, the second information processing device is configured to execute an operation transmission process of transmitting second operation data indicating an operation content to the image forming device, not via the cloud storage,
• in a case where the image forming device receives the second operation data from the second information processing device, the image forming device is configured to execute a process corresponding to an operation indicated by the received second operation data,
• in a case where the image forming device starts providing the first remote operation by executing process including the image upload process, the image forming device enters a first remote operation providing state until an ending condition of the first remote operation is satisfied,
• in a case where the image forming device starts providing the second remote operation by executing process including the image upload process, the image forming device enters a second remote operation providing state until an ending condition of the second remote operation is satisfied,
• the image forming device is configured to start providing the second remote operation, in a case where the start instruction of the second remote operation is received from the second information processing device in a state where the image forming device is not in the first remote operation providing state, and
• the image forming device is configured to start providing the first remote operation, in the case where the start instruction of the second remote operation is received from the second information processing device in a state where the image forming device is not in the first remote operation providing state.
