1. An image forming apparatus comprising:
a central processing unit (CPU), and
a storage medium having program instructions stored thereon, execution of which by the CPU causes the image forming apparatus to provide functions of:
an operation unit that receives an input signal based on a user input, and
a management unit that manages a plurality of modes of the image forming apparatus, the plurality of modes including a first mode and a second mode, wherein the second mode is for remote maintenance; and
a transceiver configured to transmit connection request data to a maintenance apparatus and receive connection reply data from the maintenance apparatus in response to the connection request data,
wherein the execution of the program instructions by the CPU causes the image forming apparatus to further provide functions of:
a restricting unit that restricts communication with an external apparatus; and
a control unit that
controls the management unit to shift a current mode of the image forming apparatus from the first mode to the second mode in response to receiving the input signal,
controls the transceiver to transmit the connection request data to the maintenance apparatus in response to receiving the input signal, and
controls the restricting unit to restrict the communication with the external apparatus in response to the transceiver receiving the connection reply data.
