In the Address bar of the web browser:
Microsoft Internet Explorer: Type "http://" followed by the IP address of the scanner (ie. xx.xxx.xx.xxx) followed by ":50080" (colon, port number).
Google Chrome: Type the scanner's IP address followed by a colon and the port number (i.e. 12.345.67.890:50080).
Mozilla's Firefox: The same rule applies as Microsoft's IE -
http://xx.xxx.xx.xxx:50080 (xx.xxx.xx.xxx is the scanner's IP address).
NOTE: If using SSL, the port you need to use is "50443" (not "50080").
