Abstract: In a facsimile system adapted to receive data via a LAN (Internet facsimile system), when the facsimile machine is unable to print or otherwise process the received data, and has no mass storage device, the received data is rerouted to the other terminal connected to the LAN so that the received data may be readily retrieved at all times. Such a situation can occur as a result of a failure of the printer unit, running out of printing paper, experiencing an unchanged state of the image memory for more than a prescribed time period, experiencing a memory-full state of the image memory for more than a prescribed time period, and detecting the received data to be based on a format which the facsimile system is unable to handle. Therefore, the received data can be made readily available for the interested party, and the safety of the received data can be improved.

Abstract: A RARP processing section of a network scanner obtains a MAC address corresponding to a user name from a MAC address table, and broadcasts a RARP request by use of this MAC address. While, a PC sends a pair of a self-IP address and a mail address to a RARP processing section in response to the RARP request. After obtaining an IP address of this PC, a scanner scans an original, and generates e-mail to which the image is appended. Next, an SMTP transmitting section directly transmits the generated e-mail to the PC. At this time, the SMTP transmitting section uses the IP address of PC obtained by the RARP processing section. In the network to which HDCP is introduced, the network scanner automatically obtains the IP address of PC, and directly transmits image data to the PC.
