Check the scanner
connection status."

Causes
Network communication is
not available because the
machine's IP address could
not be obtained from the
host name. If only "IPv6" is
set to [Active], the IPv6
address might not be
obtained.
Solutions
• Check whether the machine's host
name is specified in the Network
Connection Tool. For the WIA
driver, check the [Network
Connection] tab in the properties.
• Use Web Image Monitor to set
"LLMNR" of "IPv6" to [Active].
• In Windows XP, IPv6 address
cannot be obtained from the host
name. Specify the machine's IPv6
address in the Network
Connection Tool.
