The possible causes and remedies for problems when connecting to the Internet or intranet
are as follows:
When connection to the Internet/Intranet fails
Cause
Remedy
The Authentication feature
used on the remote server is
not supported by the machine.
Only Basic Authentication is supported by the machine. The
machine does not support NTLM/digest.
For security purposes, change to the Authentication feature
using SSL.
The remote linkage services
used does not support the
model or accessories of the
machine.
Purchase products/models/accessories supported by the remote
linkage services.
The IP address is incorrect.
Confirm the IP address. If the IP address is incorrect, either set a
static IP address or resolve the IP address using DHCP or
Autonet.
The IP gateway address is
incorrect.
Set the correct IP gateway address when connecting to the proxy
server, or to a Web server via the IP gateway.
The subnet mask is incorrect.
Set the correct subnet mask corresponding to your environment.
The DNS server address is
incorrect.
Confirm the DNS server address.
The DNS server selected
cannot resolve the address.
Select a DNS server that can resolve the address.
• When connecting via the proxy server
Set the IP address of a DNS server that can resolve the address
of the proxy server.
• When not connecting via the proxy server
Set the IP address of a DNS server that can resolve the
destination address.
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 desired server, or the proxy
server is down.
Confirm whether the desired server or the proxy server is
operating correctly.
The network cable is not
connected, or broken.
Confirm whether the network cable is correctly connected. We
recommend using a spanning-tree configuration, with which
network disconnection rarely occurs.
Cannot communicate because
of overloading of the server
application.
Wait for a while and try accessing again.
An error that is not displayed
on the control panel occurs.
Even though an error occurs during background processing, no
massage appears on the control panel. Display the [Job Status]
screen or print the Job History Report to confirm the result.
