JPEG The acronym for Joint Photographic Experts Group. It is a file format used to
save image data. (The file extension is ".jpg"). The compression ratio is generally
1/10 to 1/100. JPEG is an effective method to compress photographs and other
natural images.
Kerberos A network authentication system used for Windows 2000 or later, used for Active
Directory authentication. Kerberos arranges an authentic site within the network
to provide two-phase authentication processes of users login and the use of net-
work resources, allowing users to be securely and efficiently authenticated.
LAN The acronym for Local Area Network, which is a network constructed by con-
necting computers on the same floor, in the same building, or in neighboring
buildings.
LDAP The acronym for Lightweight Directory Access Protocol, which is a protocol used
to access a database that can manage E-mail addresses and environmental in-
formation of network users on the Internet, intranet, or other TCP/IP network.
LLMNR The acronym for Link-local Multicast Name Resolution, which is a protocol used
for the name resolution of neighboring computers. LLMNR uses simple ex-
change of request and response messages to perform name resolution of neigh-
boring computers without configuring DNS server or clients.
LLTD The acronym for Link Layer Topology Discovery, which is a technology investi-
gating how the devices on the network are connected. Network devices with this
technology are recognized by Windows Vista/Server 2008 on the network, and
displayed as icons configured on the network map of Windows Vista.
Local printer A printer connected to a parallel or USB port of a computer.
Long original A function to send original pages longer than the standard size. Long size doc-
uments can be sent by selecting this function.
LPD The acronym for Line Printer Daemon, which is a platform-independent printer
protocol running on the TCP/IP network. The protocol was originally developed
for BSD UNIX, and has become one of the printing protocols typically used
among general computers.
LPR/LPD The acronym for Line Printer Request/Line Printer Daemon, which is a printing
method via the network, used for Windows NT or UNIX based systems. It uses
TCP/IP to output printing data from Windows or UNIX to a printer on the network.
MAC address MAC is the acronym for Media Access Control. MAC address is an ID number
unique to each Ethernet card, enabling the cards to send and receive data to and
from each other. A Mac address consists of 48-bit numbers. The first 24 bits are
controlled by IEEE and used to allocate a unique number to each manufacture,
whereas the latter 24 bits are used by each manufacturer to assign a unique
number to each card.
Main Scanning The operation of scanning a document optically, and converting the document
into image data.
Main scanning direc-
tion The horizontal direction for scanning originals.
Manual transmission An operation to send a fax while checking the status of the receiver.
MDN The acronym for Message Disposition Notifications, which is a message sent to
confirm that the mail has been unsealed, a response to a sender when the sender
requests for doing so.
Memory A storage device used for storing data temporarily.
Some types of memory retain data even after the power is turned off, while oth-
ers not.
Memory overflow A condition where the fax memory becomes full while scanned documents or
temporarily stored documents are saved.
Memory transmission A method used to start a fax transmission after scanning originals and storing
them in memory. If memory transmission is used, the total number of pages are
automatically printed in the page number of the transmission source information
and an image of the first page of the sent document is printed in the transmission
report. However, the memory may become full if the document contains many
pages, or there is a large amount of information due to high image quality.
