16 Glossary
Note
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.
ADF
An Automatic Document Feeder (ADF) is a mechanism 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 pseudo standard
throughout the industry, even among non-Microsoft platforms.
DADF
A Duplex Automatic Document Feeder (DADF) is a mechanism that
will automatically feed and flip 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.
DNS
The Domain Name Server (DNS) is a system that stores information
associated with domain names in a distributed database on
networks, such as the Internet.
Dot Matrix Printer
A dot matrix printer refers to a type of computer printer with a print
head that runs back and forth on the page and prints by impact,
striking an ink-soaked cloth ribbon against the paper, much like a
typewriter.
DPI
Dots Per Inch (DPI) is a measurement of resolution that is used for
scanning and printing. Generally, higher DPI results in a higher
resolution, more visible detail in the image, and a larger file size.
DRPD
Distinctive Ring Pattern Detection. Distinctive Ring is a telephone
company service which enables a user to use a single telephone line
to answer several different telephone numbers.
Duplex
A mechanism that will automatically flip over a sheet of paper so that
the machine can print (or scan) on both sides of the paper. A printer
equipped with a Duplex can print double-sided of paper.
Duty Cycle
Duty cycle is the page quantity which does not affect printer
performance for a month. Generally the printer has the lifespan
limitation such as pages per year. The lifespan means the average
capacity of print-outs, usually within the warranty period. For
example, if the duty cycle is 48,000 pages per month assuming 20
working days, a printer limits 2,400 pages a day.
ECM
Error Correction Mode (ECM) is an optional transmission mode built
into Class 1 fax machines or fax modems. It automatically detects
and corrects errors in the fax transmission process that are
sometimes caused by telephone line noise.
