What is a device server?The device server allows you to use the scanner function of 
the machine over a network. Note that multiple computers 
cannot connect to the scanner function of the machine at the 
same time.–
What operating systems are 
supported?Supported operating systems are Windows 2000, Windows 
XP and Windows Vista. TCP/IP needs to be available.–
What network interface is 
supported?10BASE-T/100BASE-TX wired network interface is 
supported.
Auto Negotiation is supported and the network is 
automatically detected by connecting the network cable.Start 
Guide
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.–

addresses automatically.
 The automatic process may have assigned an IP address to 
the machine with which the network communication cannot 
be established with the computer.
 Configure IP addresses in the same local environment 
where the router or server does not exist when installing the 
machine for the first time.–
Check if there is any security software function such as 
firewall in the computer.
The security software function may be interrupting network 
communication with the machine. Disable the function to see if 
the problem continues. For information on disabling the 
function of the security software, refer to the manual or online

TROUBLESHOOTING
Why does the installation of the 
driver software hang?You may be logging in as a non-admin user or using fast user 
switching.
You need to log in as an administrator to install or configure 
the driver software. Also, fast user switching is not supported. 
If you are logging in as a non-admin user or using fast user 
switching, log off and log in again as an administrator.–
The machine replies to ping, 
however it can not be seen on the 
network.There may be a network device with the same IP address as 
the machine on the network, and the device that replied to 
ping may not be the machine. (Try arp -a command after 
executing ping command.)
Check the IP address of each device on the network, then 
assign an IP address on the machine.
Example: In the list displayed after executing arp -a 
command, if the Ethernet address (Physical address) shown 
on the right side of the IP address (Internet address) is 
different from the machines Ethernet address, another 
network device with the same IP address replied.
Example: If a device replied to ping even the LAN cable is 
disconnected from the machine, the device has the same IP 
address.–
Security software such as firewall may exclude the 
communication to the machine.
Disable the security software such as firewall and verify again. 
For information on disabling the function of the security 
software, refer to the manual or online help of the software.–
Why does the IP address change 
every time I turn on the machine?In the environment the machine is operating, there may be a 
router or a server (DHCP server) with the function to assign 
an IP address. Check the DHCP server and try one of the 
following.
 Verify the range of the IP address the DHCP server assigns, 
and assign a unique IP address that is out of the range. The 
IP address has to be in the same segment. The 
DHCP/BOOTP/RARP protocol of the machine needs to be 
disabled.
Example: If the range of the IP address the DHCP server 
assigns is from 192.168.0.2 to 192.168.0.32, assign an IP 
address which has not been used in the network from the 
range between 192.168.0.33 and 192.168.0.254. When you 
assign an IP address, make sure that the same IP address 
has not been assigned on multiple devices. The DHCP 
server itself may have the IP address such as 192.168.0.1 
or 192.168.0.254. Please verify.
 Register the machine on DHCP server in order to assign a 
fixed IP address. (Refer to your DHCP server manual for 
how to configure.)–
The network settings of the 
machine are initialised to the 
factory default every time the 
machine is booted.The configuration of the machine may not have been 
completed properly. Typically the setup information is not 
properly registered if you canceled the setup while transferring 
the configuration data to the machine, and if you experienced 
a network stoppage problem during the setup.
Please retry the setup procedure again.Start
