Description
CPLD
Complex Programmable Logic Device - a programmable logic device with
complexity between that of PALs and FPGAs, and architectural features of
both. The building block of a CPLD is the macro cell, which contains logic
implementing disjunctive normal form expressions and more specialized
logic operations.
CRU
Customer Replaceable Unit
CRUM
Customer Replaceable Unit Memory
CYMK
Toner colors for machine; Y=yellow, C=cyan, M=magenta, and K=black
DADF
Duplexing Automatic Document Feeder
DC
Direct Current is type of power for machine components. Machine converts
AC power from power source to DC power.
DIMM
Dual In-line Memory Module - a series of dynamic random access memory
integrated circuits.
DLD
Download Direct Method - Down Load Direct (DLD) was developed to
accelerate downloads
DMA
Direct memory access (DMA) is a feature of modern computers and micro-
processors that allows certain hardware subsystems within the computer to
access system memory for reading and/or writing independently of the cen-
tral processing unit.
DMM
Digital Multimeter is generic name for meter that measures voltage, current,
or electrical resistance.
DNS
Domain Name System - a hierarchical naming system for computers, ser-
vices, or any resource connected to the Internet or a private network. It
associates various information with domain names assigned to each of the
participants. Most importantly, it translates domain names meaningful to
humans into the numerical (binary) identifiers associated with networking
equipment for the purpose of locating and addressing these devices world-
wide.
DTMF
Dual-Tone Multi-Frequency signaling - is used for telecommunication sig-
naling over analog telephone lines in the voice-frequency band between
telephone handsets and other communications devices and the switching
center.
Duplex
2-sided printing or copying
EA
Emulsion Aggregation (toner)
EEPROM
Electrically Erasable Programmable Read-Only Memory - a type of non-vol-
atile memory used in computers and other electronic devices to store small
amounts of data that must be saved when power is removed, e.g., calibra-
tion tables or device configuration.
EME
Electromagnetic Emissions are emitted from machine during normal opera-
tion and power of these emissions are reduced by machine design features.
ESD
Electrostatic Discharge. A transfer of charge between bodies at different
electrostatic potential.
ESG
European Solutions Group - also referred to as XE (Xerox Europe)

Description
First In, First Out - an abstraction in ways of organizing and manipulation of
data relative to time and prioritization. This expression describes the princi-
ple of a queue processing technique or servicing conflicting demands by
ordering process by first-come, first-served (FCFS) behaviour: what comes
in first is handled first, what comes in next waits until the first is finished, etc.
FAX Over Internet Protocol
Field-Programmable Gate Array - an integrated circuit designed to be con-
figured by the customer or designer after manufacturing
Fast Scan (direction) - LE - to - TE
File Transfer Protocol - a standard network protocol used to exchange and
manipulate files over a TCP/IP-based network, such as the Internet.

Intermediate Belt Transfer
Interface
Intermediate Image Overwrite
Image Input Terminal - the Scanner/CCD portion of the machine
Internet Protocol Security - a protocol suite for securing Internet Protocol
(IP) communications by authenticating and encrypting each IP packet of a
data stream. IPsec also includes protocols for establishing mutual authenti-
cation between agents at the beginning of the session and negotiation of
cryptographic keys to be used during the session.
Image Output Terminal - the ROS/Xero/paper handling/ fusing portion of the
machine
Image Management Software - Windows and Macintosh software for view-
ing, organizing, cataloging, managing, browsing, storing, sharing, and print-
ing images.
Image Processing Subsystem
Image Quality
Job-based Accounting
Joint Bi-level Image Experts Group - JBIG was designed for compression of
binary images, particularly for faxes, but can also be used on other images.
1000 copies
a computer network authentication protocol, which allows nodes communi-
cating over a non-secure network to prove their identity to one another in a
secure manner.
