Abstract:
An image forming system includes an image forming apparatus and a host apparatus. The image forming apparatus counts an idle state time during which the image forming apparatus is not in use, and, when the idle state time reaches a predetermined threshold time, transmits a notice screen display command to the host apparatus. The host apparatus displays a notice screen, and, when a turn on time extension menu is selected on the notice screen, transmits a turn on time extension command to the image forming apparatus. When the turn on time extension command is received, the image forming apparatus resets a timer unit and recounts the idle state time, and, when the turn on time extension command is not received for a predetermined time, is automatically turned off.
