Protocol Settings
This section describes how to specify the protocol settings for the machine using the control panel. If
you are configuring the settings for the first time, use the control panel of the machine.
After configuring the settings, you can change the content by using software other than the control
panel of the machine. For details, see e-Manual > Network.
When using functions to access external servers on the internet, you may not be able to access them due to the
settings of firewalls, etc. In this case, consult your network administrator.
TCP/IPv4 Settings
This section describes the procedure for setting TCP/IPv4 using the control panel. After specifying the
settings for TCP/IPv4, follow the procedure in “Settings Common to TCP/IPv4 and TCP/IPv6,” on p. 5-
17 to specify the required settings, and the procedure in "Confirming TCP/IPv4 Settings," on p. 5-24 to
check whether the network settings are correct. If the settings for TCP/IPv6 are already specified and
you have finished specifying the settings common to TCP/IPv4 and TCP/IPv6, only check the network
settings after completing this procedure.
If you want to use IPv6 communications at the same time, follow the procedure in "TCP/IPv6
Settings," to specify the required settings, and the procedure in "Confirming TCP/IPv6 Settings," on p.
5-25 to confirm the settings.
1 On the TCP/IP Settings screen, press [IPv4 Settings] → [Use IPv4].
