Abstract
A facsimile apparatus includes a recording unit including an ink-jet recording apparatus for recording image data, a main power supply unit for supplying electric power, a central control unit, to which electric power is supplied from the main power supply unit, for controlling the operation of the entire apparatus, a main-power-supply control unit for controlling on/off operations of the main power supply unit, and a secondary battery unit, charged by the main power supply unit, for supplying the main-power-supply control unit with electric power. The apparatus is operable in an operational mode in which the main power supply unit is turned on by a starting signal output from the main-power-supply control unit, and the main power supply unit supplies a main body of the apparatus with electric power and charges the secondary battery unit, and a standby mode in which the main power supply unit is turned off and the secondary battery unit supplies the main-power-supply control unit with electric power. The main-power-supply control unit starts the main power supply unit in order to charge the secondary battery unit in the standby mode. When starting the main power supply unit in order to charge the secondary battery unit, a recovery operation of a head of the ink-jet recording apparatus is performed by suctioning or discharging ink within the head.
