Checking Your Network Environment

The diagram below shows an example network. Confirm the details of the network environment connected to the machine, and then perform the necessary operations.
Use TCP/IP to set up the network connected to the machine.
In addition to IPv4 (Internet Protocol Version 4), the machine also supports IPv6 (Internet Protocol Version 6), and has a dual stack configuration that enables it to communicate with both IPv4 and IPv6 networks. The functions of IPv4 are always enabled, and you can select whether to use the functions of IPv6.
For details, see Connecting the Machine to a TCP/IP Network.
IMPORTANT
If you want to use the machine as a network scanner, it must be connected to a computer over an IPv4 network.
NOTE
The sample network connection diagram above shows a Windows-based network environment. The machine works best in a Windows-only environment, but can be used in a network of different operating systems as well, including Windows, UNIX, Linux, and Mac OS X. (System Requirements)
