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.
Emulation
Emulation is a technique of one machine obtaining the same results as another.
An emulator duplicates the functions of one system with a different system, so that the second system behaves like the
first system. Emulation focuses on exact reproduction of external behavior, which is in contrast to simulation, which
concerns an abstract model of the system being simulated, often considering its internal state.
