8.2 Network Connection Troubleshooting

Another host or communication device is connected using the same IP address as the scanner.

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.

Access is denied due to the establishment of a firewall between the server and the scanner.

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.

The network Link Speed/Duplex Mode for the scanner and server are different, or "Auto-Negotiation" is not supported by the server.

Action

zFor this scanner, the default [Link Speed/Duplex Mode] value is [Auto-Negotiation].

zOn the [Network Status] window, match the scanner and server's network Link Speed/Duplex Mode settings. If the problem persists in spite of having set both the scanner and server's network Link Speed/Duplex Mode settings to [Auto-Negotiation], select something other than [Auto-Negotiation] and check again.

zFor more details about the [Network Status] window, refer to "4.8.7 Checking the Network Operating Status" (page 121).
