I cannot search the machine using
the software utility.
The firewall on your computer might prevent the computer
from connecting to the machine. You need to configure the
firewall settings to allow connection between them.
• When using the configuration utility (Set the IP Address):
If you cannot search the machine when using configuration
utility "Set the IP Address", you need to disable the firewall
during the setting. For information on disabling the firewall,
refer to the manual or online help of your operating system
or firewall software.
• When using the connection utility (SC-Scan A):
If you cannot search the machine when using the
connection utility "SC-Scan A", you need to add SC-Scan A
and UDP port number "19540" to the firewall exception list.
For information on adding SC-Scan A and UDP port number
"19540" to the firewall exception list, refer to the manual or
online help of your operating system or firewall software.

What is the difference between a
device server and print server?
The major difference is whether the connection to the
scanner/printer function of the machine from the computers
on the network is 1:1 basis (device server) or 1:n basis (print
server).
SC-Scan A establishes a connection to the scanner function
and enables you to use it as if it was connected locally to your
computer. Therefore, if the scanner function is accessed by a
computer (in use by another user), the scanner function
cannot be shared with other computers.
