■ 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.

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.
