8.2.2 Other Network Connection Troubleshooting

There are many reasons why a network connection may not be possible.

The following section provides information about general troubles that may occur when connecting to a network.

If the cause of the problem is unknown or the problem persists, check the items in "8.4 Points to Check before Contacting Your FUJITSU Scanner Dealer" (page 467) and contact your FUJITSU scanner dealer or an authorized FUJITSU scanner service provider.

Failure to Connect to a Server Using Its IP Address

If a server cannot be connected to by using its IP address, and does not respond to a ping test, try the following steps:

Connection error between a server and the scanner, or problem with the LAN cable.

Action

Check that the LAN cable has been attached to both the scanner and server correctly.

If the server is connected using a LAN cable (straight type), in case Auto MDI/MDI-X (automatic selection) is not supported, a LAN cable (crossover type), switch, or router is required between the scanner and server.

If this is not the case, the LAN cable may be faulty. Find a LAN cable that functions normally and try again.

IP address or subnet mask is invalid.

Action

On the [IP Address] window, check that the IP address or subnet mask settings are correct. For more details about the [IP Address] window, refer to "4.8.1 Giving the Scanner an IP Address" (page 113).

When using DHCP, the DHCP server does not operate normally, or there is a problem with the DHCP server settings.

Action

If using DHCP, on the [Network Status] window, check that IP address, subnet mask, and default gateway settings are all correct.

If these settings are not correct, the DHCP server may not operate normally, or the DHCP server may not assign valid IP addresses because of restricted number of leases or MAC address validation.

Check the DHCP server connection status and the details of the server settings.

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