7.2.2 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
"7.4
Points to Check before Contacting Your FUJITSU Scanner Dealer" (page 394) 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:
■
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), 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.
■
Action
Refer to "4.7.1 Giving the Scanner an IP Address/DHCP" (P.101) or refer to "G.3.1 Giving the
Scanner an IPv4 Address" (P.462) / "G.3.2 Giving the Scanner an IPv6 Address" (P.463) if the
IPv6 function is enabled and then check the settings that you have configured such as the IP
address and the subnet mask (subnet prefix length for an IPv6 address) are configured correctly.
■
Action
If you use DHCP, refer to "4.8.2 Checking the Network Operating Status" (P.110) or "G.3.5
Checking the Network Operating Status" (P.467) and check that the IP address, subnet mask
(subnet prefix length for an IPv6 address), and default gateway for the scanner are all set
correctly.
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.
Connection error between a server and the scanner, or problem with the
LAN cable.
The settings you have configured on the [IP Address] window, or the
[IPv4 Address] window/[IPv6 Address] window when the IPv6 function is
enabled, are invalid.
When DHCP is used, the DHCP server does not operate normally, or
there is a problem with the DHCP server settings.
