ABSTRACT:
An image processing apparatus executes the processing of updating control information kept in the controlling units included in it without suspending an on-going processing and delaying the execution of a new processing request with less power consumption. When the controlling units are in a sleep mode or in non-energized state, NIC determines whether or not updating of firmware kept in each controlling unit is necessary by communicating with the information delivery server. The NIC controls an energization switching circuit to start up exclusively the controlling unit keeping the firmware determined necessary to be updated and replaces the firmware kept in the started controlling unit with the latest version of firmware obtained from the information delivery server.
