TCP/IP Error

Cause 1

Because the IP address cannot be obtained automatically via DHCP, RARP, or BOOTP, [IP Address] in <IP Address Settings> (in the IPv4 Settings) is set to '0.0.0.0'.

Remedy

See "TCP/IPv4 Settings" to specify the correct IPv4 address.

Cause 2

'0.0.0.0' is set as a static IPv4 address in [IP Address] of <IP Address Settings> (in the IPv4 Settings).

Remedy

See "TCP/IPv4 Settings" to specify the correct IPv4 address.

Cause 3

The IPv6 addresses are not properly set up.

Remedy

Check the following:

Confirm that the settings for the addresses (<Use Stateless Address>, <Use Manual Address>, or <Use DHCPv6>) are set to 'On'.

If you are using a stateless address or DHCPv6, confirm that addresses can be obtained.

If addresses cannot be obtained, check the settings of the router or DHCPv6 server.

NOTE
It may take several minutes for a stateless address to be determined.

Cause 4

The IP address of the DNS server is not correct.

Remedy

See "TCP/IPv4 Settings" or "TCP/IPv6 Settings" to check the IP address of the DNS server.

Cause 5

Sending could not be performed due to a lack of resources in the TCP/IP protocol stack.

Remedy

See "TCP/IPv4 Settings" or "TCP/IPv6 Settings" to specify the correct IPv4/IPv6 address.
