electronic document distribution worldwide. PDF is a universal file format that preserves all the
fonts, formatting, graphics, and color of any source document, regardless of the application and
platform used to create it.
Authentication – Authentication verifies the identity of the MFD user by requiring him/her to enter
a valid user name and password via the MFD's touch screen. These "login credentials" are
compared against a database of authorized users, thus granting or denying access to system
functions. Authentication allows the System Administrator to improve security by monitoring
machine usage.
dpi (dots per inch) – dpi is a measure of resolution for input devices, such as copiers and
scanners, and output devices, such as printers and fax machines. Also see Resolution.

the exchange of data. The Directory Server must also support LDAPS, otherwise address
lookup through LDAPS is not supported.
NIC (Network Interface Card) – A NIC is an expansion board inserted into a device so the
system can be connected to a network.
Operating System – An operating system is the most important program that runs on a
computer. Every general-purpose computer must have an operating system to run other
