Abstract:
1. An image forming apparatus comprising: a power supply unit configured to supply power from an AC power source to function units in the image forming apparatus; a power detection unit a detect a value of the power supplied by said power supply unit from the AC power source to the function units in the image forming apparatus; and a first control unit configured to acquire the value detected by said power detection unit to control the power supply by said power supply unit based on the acquired value, wherein said first control unit is configured to execute: a specification task for specifying a state of the image forming apparatus; a failure determination task for determining, based on the state of the image forming apparatus specified in said specification task and the value detected by said power detection unit, whether or not there is an electrical failure; a self-diagnostic task for separately supplying, by said power supply unit, the power from the AC power source to the function units in the image forming apparatus and specifying an electrically failed part based on a state of the image forming apparatus estimated at the separate supply and the value detected by said power detection unit, if it is determined in said failure determination task that there is an electrical failure; and a first notification task for notifying a user or an administrator of the failed part specified in said self-diagnostic task.
