Problem Action
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 Sta-
tus" screen, refer to "4.7.18 Checking the

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

Restart the server.
If a duplicate IP address connection from
another host or communication device
exists on a LAN, both 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.
If a firewall has been established between
the server and the scanner, check that it
has not been set to deny access to the net-
work.
