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.

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 machine's 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.

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 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.

Guide

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.
