Abstract:
An image forming system comprising:a plurality of image forming apparatuses each of which includes:an image scanner scanning an original document so as to generate image data;an image processing unit processing the image data generated by said image scanner;an encoding unit encoding the image data processed by said image processing unit;an interface unit transmitting the image data encoded by said encoding unit, said interface unit also receiving image data from one of said image forming apparatuses;a memory unit storing the image data encoded by said encoding unit and the image data received by said interface unit;a decoding unit decoding the image data stored in said memory unit; anda printing unit printing an image by the image data decoded by said decoding unit;a transmission path connecting said interface unit of each of said image forming apparatuses so that the encoded image data is transmitted between the image forming apparatuses; andmeans for diagnosing any one of the interface units of any one of said plurality of image forming apparatuses and for diagnosing the transmission path when a power of each of said plurality of image forming apparatuses is turned on.
