(57) In an MFP, a system controller (105) is connected to an engine (200) via a universal transmission line (301) and a dedicated transmission line (302). When MFP is powered, the system controller sends a mode signal to the engine via the dedicated transmission line (302). If the mode signal indicates that the power mode is to be set to a normal mode, the engine activates predetermined components. The system controller and the engine then establish communication via the universal transmission line (301). After establishing the communication, if the mode signal indicates that the power mode is to be set to a mode other than the normal mode, the system controller sends a setting command to the engine via the universal transmission line (301) to set the power mode to any of a plurality of power-saving modes.
