Image information transmitting system, scanner apparatus and user terminal apparatus, and method for registering user terminal information to scanner apparatus

摘要

PC broadcasts a search packet on a network (ST505), and waits for the response (ST506). A network scanner receives the search packet and determines whether or not the received search packet is a group name to be responded (ST507). When determining it as the group name to be responded, the network scanner sends back a search response packet to PC (ST509). When receiving the search response packet, PC transmits a registration packet to the network scanner. When receiving the registration packet, the network scanner extracts user terminal information from the registration packet (ST511) and registers it to address notebook data (ST512). After that, the network scanner transmits a registration response packet to PC (ST513).
