Specifying Network Security Level
This can be specified by the network administrator. This setting lets you change the security level to limit
unauthorized access. You can make network security level settings on the control panel, as well as Web
Image Monitor. However, the protocols that can be specified differ.
Set the security level to [Level 0], [Level 1], or [Level 2].
Select [Level 2] for maximum security to protect confidential information. Make this setting when it is
necessary to protect confidential information from outside threats.
Select [Level 1] for moderate security to protect important information. Use this setting if the machine is
connected to the office local area network (LAN).
Select [Level 0] for easy use of all the features. Use this setting when you have no information that needs
to be protected from outside threats.
