Abstract:
1. An image forming system comprising an image forming apparatus having a light emitter and an information terminal, the image forming apparatus including: a visible light output unit outputting information stored in the image forming apparatus by emitting visible light from the light emitter, and an output control unit controlling operation of the visible light output unit, the information terminal including: a light receiver receiving the visible light emitted from the light emitter of the image forming apparatus, and an information acquisition unit acquiring information stored in the image forming apparatus based on information obtained by receiving visible light with the light receiver, wherein when the information acquisition unit is operative in the information terminal, the information acquisition unit of the information terminal gives a light emission start request to the output control unit of the image forming apparatus, and when the light emission start request is received from the information acquisition unit, and the image forming apparatus is in a power saving mode wherein the visible light output unit is not outputting information using the light emitter, the output control unit of the image forming apparatus controls operation of the visible light output unit to output the information stored in the image forming apparatus by emitting visible light from the light emitter.
