Network-related Problems

Internet/Intranet Connection Problems

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.
