A network peripheral device connected to a network via a router obtains remote servicing instructions over the network. Initially, a first packet sent from a remote service organization is received by a network peripheral device via the network, the first packet including a request for servicing information from the network peripheral device. Next a second packet is sent automatically upon receipt of the first packet from the network peripheral device to the remote service organization via the network, the second packet including the requested peripheral servicing information. Thereafter, a third packet sent from the remote service organization to the network peripheral device via the network is received by the network peripheral device, the third packet including an instruction to execute a peripheral servicing function. Finally, the peripheral servicing function is executed by the network peripheral device automatically in response to the third packet.

An HTTP server for an image input device is provided in which when an image is input and a file for the image is created for access by the server, an HTML link to the file is automatically generated by which a web browser can retrieve the file over a TCP/IP network. An HTTP server for an image input device is provided, in which an identification code is obtained for an image file created for an image input by the image input device. An HTML page which includes an HTML link to the image file created for the input image is automatically generated upon receipt by the server of a TCP/IP packet which includes a request to retrieve an identified web page, the identified web page having a predetermined relationship to the identification code for the image file. A TCP/IP packet which includes the generated HTML page is caused to be sent over a TCP/IP network.

A method controls a network device on a local area network (LAN) to operate as a list manager which maintains a list of device addresses for the LAN, and to operate as a slave which provides a device address of the network device to a list manager. The method comprises the steps of determining whether a list manager is operating on the LAN, controlling the network device to operate as a slave on the LAN when the determining step determines that a list manager is operating on the LAN, and controlling the network device to operate as the list manager for the LAN when the determining step determines that no list manager is operating on the LAN.

Status information concerning a condition of a network peripheral device connected to a network is automatically communicated to a remote service organization. First, a condition of the network peripheral device is detected. Then, in response to the detected condition, status information is automatically obtained, the status information corresponding to the detected condition. Finally, upon obtaining the status information, a packet is automatically transmitted to the remote service organization via the network, the packet containing the status information.

Automatic service requests over the world wide web

Process steps to provide communication between a web browser capable of initiating execution of a platform-independent segment of executable code and a peripheral having an HTTP server and an SNMP agent. A first packet is transferred to the HTTP server, and, in response, a file is transmitted to the web browser. The file contains a reference to a platform-independent segment of executable code. Upon processing the file, this code segment is requested from the HTTP server. After the web browser receives the executable code from the HTTP server, execution of the code segment is initiated in order to create an SNMP client. Execution of the code segment also causes a packet to be sent from the SNMP client to the SNMP agent in the peripheral. In response to this packet, information concerning the peripheral is transferred from the SNMP agent to the SNMP client.
