6.3.2 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 "6.5 Points to
Check before Contacting Your FUJITSU Scanner Dealer" (page 249) and contact your FUJITSU
scanner dealer or an authorized FUJITSU scanner service provider.
Failure to connect to a remote computer using its IP address
If a remote computer cannot be connected to using its IP address, and does not respond to a ping
test, try the following steps:
No. Problem Action
1 Connection error between a remote computer
and the scanner, or problem with the LAN
cable.
Check that the LAN cable has been attached to
both the scanner and remote computer
correctly.
If the remote computer is connected using a
LAN cable (straight type), in case auto-mdi
(automatic selection) is not supported, a LAN
cable (crossover type), switch, or router is
required between the scanner and remote
computer.
If this is not the case, the LAN cable may be
faulty. Find a LAN cable that functions
normally and try again.
2 IP address or subnet mask is invalid. On the "IP Address" screen, check that the IP
address or subnet mask settings are correct.
For more details about the "IP Address"
screen, refer to "3.6.1 Giving the Scanner an
IP Address" (page 57).
3 When using DHCP, the DHCP server does not
operate normally, or there is a problem with
the DHCP server settings.
If using DHCP, on the "Network Status"
screen, 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"
screen, refer to "3.6.11 Checking the Network
Operating Status" (page 89).
