Internet/Intranet Connection Problems

When connection to the Internet/Intranet fails
Cause
The Authentication feature used
on the remote server is not
supported by the machine.
The remote linkage services used
does not support the model or
accessories of the machine.
The IP address is incorrect.
The IP gateway address is
incorrect.
The subnet mask is incorrect.
The DNS server address is
incorrect.
The DNS server selected cannot
resolve the address.
The address that does not use a
proxy server is incorrect.
The desired server, or the proxy
server is down.
The network cable is not
connected, or broken.
Cannot communicate because of
overloading of the server
application.
An error that is not displayed on
the control panel occurs.
Remedy
Unable to transmit because of an error.
Check the Transmission Results in the Confirmation Report - Job
Undelivered. If the status code is displayed, refer to "Status Codes".
Remedy
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.
Purchase products/models/accessories supported by the remote
linkage services.
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.
Set the correct IP gateway address when connecting to the proxy
server, or to a Web server via the IP gateway.
Set the correct subnet mask corresponding to your environment.
Confirm the DNS server 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.
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.
Confirm whether the desired server or the proxy server is operating
correctly.
Confirm whether the network cable is correctly connected. We
recommend using a spanning-tree configuration, with which network
disconnection rarely occurs.
Wait for a while and try accessing again.
Even though an error occurs during background processing, no
message appears on the control panel. Tap Jobs on the Home screen,
or print the Job History Report to confirm the result.
