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
increase s, the n umber of po ssible col ors becom es impracti cally lar ge for
a color ma p. 1-bit color is com monly c alled as mon ochrome o r black an d
white.
BMP
A bitmapped graphics format used internally by the Microsoft Windows
graphics subsys tem (GDI), a nd use d commo nly as a si mple g raphics f ile
format on that platform.
BOOTP
Bootstrap Protocol. A network protocol used by a network client to
obtain its IP add res s au tom ati ca lly . Th is i s us ua lly don e in the bootstra p
process of computers or operating systems running on them. The
BOOTP s erv ers as si gn the IP address from a p ool of addres s es to ea ch
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
monit oring instrum ents are di splay ed. They are ty pica lly f ound i n f ront of
the machine.
Coverage
It is the printing term used for a toner usage measurement on printing.
For exam ple, 5 % cov erage mean s t hat an A4 si ded p aper ha s abo ut 5%
image or te xt on it. So, if the pape r or original has comp licated imag es 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
speci fic to the DHCP clien t host requesting, generally, inform ati on
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,
receiv ed 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 Ma tr ix P ri n te r
A dot matrix prin ter ref ers to a typ e of co mp ute r prin ter with a pr in t 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 mech anism that wil l aut omati cally fl ip ov er a sheet of pape r so that th e
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
perfor mance for a month. General ly the printer has the li fespan limitatio n
such as pages per year. The lifespan means the average capacity of
print-outs, usually within the warranty period. For ex ample, if the duty
cycl e is 48,000 pag es per month as suming 20 working days, a printer
limits 2,400 pages a day.
ECM
Error Co rrectio n Mod e (ECM) i s an option al tran smis sion mode built in to
Class 1 fax machines or fax modems. It automatically detects and
corrects errors in the fax transmission process that are sometimes
caus ed by telephone line noise.
Emulation
Emulation is a technique of one machine obtaining the same results as
another.
