The table below lists possible causes and solutions for problems that may occur when
connecting to the Internet or an intranet.
Unable to Connect to the Internet or an Intranet
Possible Cause
Remedy
The IP address has not been
set correctly.
Check the IP address setting. If the IP address has not been set
correctly, specify a fixed IP address or use DHCP or Autonet to
resolve the IP address.
The IP gateway address has
not been set correctly.
Enter the IP gateway address correctly when connecting to a
proxy server or web server via an IP gateway.
The subnet mask has not been
set correctly.
Set the subnet mask correctly, to match the environment in use.
The DNS server address has not
been set correctly.
Check the DNS server address.
The DNS server selected
cannot resolve the address.
Select a DNS server that can resolve the address.
z
When connecting via the proxy server
Set the IP address of a DNS server that can resolve the
address of the proxy server.
z
When not connecting via the proxy server
Set the IP address of a DNS server that can resolve the
destination address.
The setting of the address that
does not use a proxy server is
incorrect.
Confirm whether only addresses that do not use a proxy server
are set. Even if addresses not through a proxy server are
specified using the FQDN, if a server is directly accessed using its
IP address, the registered server is not excluded. Set the address
not to use a proxy server.
Likewise, even if you directly specify an address that does not
use a proxy server, if a server is accessed with the FQDN, the
registered server is not excluded. Set an IP address with the
FQDN not to use a proxy server.
The connected server or proxy
server is down.
Check whether the server or proxy server to connect to is
working normally.
A network cable is
disconnected or broken.
Check the network cable connections. The use of a spanning
tree environment is recommended to create a network
environment resistant to disconnections.
Unable to communicate due to
the load on the server
application.
Wait a while, and then access the server again.
An error has occurred but is not
displayed on the control panel.
Errors that occur while executing background processes are not
displayed on the control panel. Print the Job History Report to
check the execution results.
