ADF

An Automatic Document Feeder (ADF) is a mechanism that will 

automatically feed an original sheet of paper so that the printer 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 printer.

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 printer. 

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 

printer 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 printer 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 

printer 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 printers 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 printer obtaining the same results as 

another.

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.
