Action
If the same IP address has already been used by another host or communication device, then
even if the other device has been given a different IP address, the server may not recognize the
scanner's "duplicate" IP address until it is rebooted. Restart the server.
If a duplicate IP address connection from another host or communication device exists on a LAN,
it will be unusable.
If a duplicate IP address connection from another host or communication device exists, pull out
its LAN cable and restart the server.
■
Action
If a firewall has been established between the server and the scanner, check that it has not been
set to deny access to the network.
■
Action
In the Network Advanced Settings for the scanner (described in
), [Link Speed/Duplex Mode] is set to the default "Auto-Negotiation".
If "Auto-Negotiation" does not operate correctly, change [Link Speed/Duplex Mode] to a fixed
mode on the scanner and server, and try again.
Another host or communication device is connected using the same IP
address as the scanner.
Access is denied due to the establishment of a firewall between the
server and the scanner.
The network [Link Speed/Duplex Mode] for the scanner and server are
different, or "Auto-Negotiation" is not supported by the server.
