6.2. Glossary
The following glossary helps you get familiar with the product by understanding the terminologies commonly used with
printing as well as mentioned in this user’s guide and service manual.
802.11
802.11 is a set of standards for wireless local area network (WLAN) communication, developed by
the IEEE LAN/MAN Standards Committee (IEEE 802).
802.11b/g/n
802.11b/g/n can share same hardware and use the 2.4 GHz band. 802.11b supports bandwidth up to 11
Mbps, 802.11n supports bandwidth up to 150 Mbps. 802.11b/g/n devices may occasionally suffer
interference from microwave ovens, cordless telephones, and Bluetooth devices.
Access point
Access Point or Wireless Access Point (AP or WAP) is a device that connects wireless communication
devices together on wireless local area networks (WLAN), and acts as a central transmitter and
receiver of WLAN radio signals.
ADF
An Automatic Document Feeder (ADF) is a scanning unit that will automatically feed an original
sheet of paper so that the machine can scan some amount of the paper at once.
AppleTalk
AppleTalk is a proprietary suite of protocols developed by Apple, Inc for computer networking. It
was included in the original Macintosh (1984) and is now deprecated by Apple in favor of TCP/IP
networking.
BIT Depth
A computer graphics term describing the number of bits used to represent the color of a single pixel in
a bitmapped image. Higher color depth gives a broader range of distinct colors. As the number of bits
increases, the number of possible colors becomes impractically large for a color map. 1-bit color is
commonly called as monochrome or black and white.
BMP
A bitmapped graphics format used internally by the Microsoft Windows graphics subsystem (GDI),
and used commonly as a simple graphics file format on that platform.
BOOTP
Bootstrap Protocol. A network protocol used by a network client to obtain its IP address automatically.
This is usually done in the bootstrap process of computers or operating systems running on them. The
BOOTP servers assign the IP address from a pool of addresses to each client. BOOTP enables 'diskless
workstation' computers to obtain an IP address prior to loading any advanced operating system.
CCD
Charge Coupled Device (CCD) is a hardware which enables the scan job. CCD Locking mechanism is
also used to hold the CCD module to prevent any damage when you move the machine.
Collation
Collation is a process of printing a multiple-copy job in sets. When collation is selected, the device
prints an entire set before printing additional copies.
Control Panel
A control panel is a flat, typically vertical, area where control or monitoring instruments are displayed.
They are typically found in front of the machine.
Coverage
It is the printing term used for a toner usage measurement on printing. For example, 5% coverage
means that an A4 sided paper has about 5% image or text on it. So, if the paper or original has
complicated images or lots of text on it, the coverage will be higher and at the same time, a toner
usage will be as much as the coverage.
CSV
Comma Separated Values (CSV). A type of file format, CSV is used to exchange data between
disparate applications. The file format, as it is used in Microsoft Excel, has become a de facto standard
throughout the industry, even among non-Microsoft platforms.
DADF
A Duplex Automatic Document Feeder (DADF) is a scanning unit that will automatically feed and
turn over an original sheet of paper so that the machine can scan on both sides of the paper.
Default
The value or setting that is in effect when taking a printer out of its box state, reset, or initialized.
DHCP
A Dynamic Host Configuration Protocol (DHCP) is a client-server networking protocol. A DHCP
server provides configuration parameters specific to the DHCP client host requesting, generally,
information required by the client host to participate on an IP network. DHCP also provides a
mechanism for allocation of IP addresses to client hosts.
DIMM
Dual Inline Memory Module (DIMM), a small circuit board that holds memory. DIMM stores all
the data within the machine like printing data, received fax data.
