Glossary
additive primary colors
The colors of red, green and blue (RGB) - which give the perception of white when combined
equally. These are the colors of the color system used by monitors and scanners.
application
A software program that helps you carry out a particular task, such as word processing or
financial planning.
ASCII
American Standard Code for Information Interchange. A standardized coding system for
assigning numerical codes to letters and symbols.
banding
The horizontal lines that sometimes appear when printing graphics. This occurs when the print
head is misaligned.
bi-level data
Image data that is composed of 1 bit per pixel. A pixel is represented by a single bit of digital
data that can be expressed as only 1 (light) or 0 (dark).
bit A binary digit (0 or 1), which is the smallest unit of information used by a printer or computer.
bit/pixel
The unit that indicates the number of bits allocated for a pixel. The larger the bit value, the more
detail of a pixel will be reproduced.
brightness
The lightness or darkness of an image.
buffer
The portion of the printer's memory used to store data before printing it.
byte A unit of information consisting of eight bits.

characters per inch (cpi)
A measure of the size of text characters, sometimes referred to as pitch.
CMYK
Cyan (blue-green), magenta, yellow, and black. These colored inks are used to create the
subtractive system array of printed colors.
color correction
A method of adjusting the color image data for a particular type of device so that the
reproduction results are as close as possible to the original colors.
color matching
A method of processing color data so that colors displayed on a computer screen closely match
colors in printouts. A variety of color-matching software is available. See also ColorSync.
color separation
A process of converting full-color images into a limited number of primary colors. Additive
primary colors (red, green, and blue) are used by the scanner, and the subtractive primary colors
(cyan, magenta, and yellow) plus black are used for printing press separation.
color space
A method that reproduces a specific color. Additive primary colors (red, green, and blue) are
used by the scanner, and subtractive primary colors (cyan, magenta, and yellow) plus black are
used for printing press separation.
ColorSync
Macintosh software that is designed to help you get WYSIWIG (what you see is what you get)
color output. This software prints colors as you see them on your screen.
cpi See characters per inch (cpi).
default
A value or setting that takes effect when the equipment is turned on, reset, or initialized.
dithering
A halftoning method in which dots are arranged in an orderly pattern. Dithering works best for
printing images with solid colors, such as charts and graphs.

document
The item, such as a sheet of paper or a book, that is placed on the document table to read.
dpi Dots per inch. The dpi measures the resolution. See also resolution.
drive A memory device, such as CD-ROM, hard disk, or floppy disk. In Windows, a letter is assigned
to each drive for easy management.
driver
A software program that sends instructions to a computer peripheral to tell it what to do. For
example, your printer driver accepts print data from your word processor application and sends
instructions to the printer on how to print this data.
dropout color
A color the scanner does not recognize and ignores. You can select and deselect dropout colors in
the scanner software.
DTP Desktop Publishing system, a system that enables you to edit a publications on a computer.
economy printing
Printing in which images are printed with fewer dots to save ink.
ESC/I
Abbreviation for Epson Standard Code for Image scanners. A system of commands that allows
you to control image scanners from your software.
ESC/P
Abbreviation for Epson Standard Code for Printers, the system of commands your computer uses
to control printers. It is standard for all Epson printers and supported by most application
software for personal computers.
exposure
A scanner function that lightens or darkens the scanned image data.
font A style of type designated by a family name.

gamma
Gamma is a value that expresses the relationship between the input and output of a device. By
adjusting the gamma, the brightness of the mid-tones of an image can be changed without
affecting the shadows and highlights.
grayscale
A scale of shades of gray from black to white. Grayscale is used to represent colors when printing
with black ink only.
high speed printing
Printing in which images are printed in both directions. This provides faster printing.
ICM Image Color Matching. Windows color management system designed to help you get
WYSIWYG (what you see is what you get) color output. This software displays colors on your
screen as they exist on the scanned documents, or prints colors as you see them on your screen.
initialization
Returns the printer to its defaults (fixed set of conditions). This happens every time you turn on
or reset the CX6500.
ink cartridge
Contains the ink the CX6500 uses when printing.
ink jet
A method of printing in which each letter or symbol is formed by precisely spraying ink onto
paper.
interface
The connection between the computer and the CX6500. A parallel interface transmits data one
character or code at a time. A serial interface transmits data one bit at a time.
interface cable
The cable that connects the computer and the CX6500.
local printer
The printer connected to the computer's port directly by interface cable.
marquee
A moveable and adjustable frame that marks the area of an image that will be previewed or

scanned.
media
Materials upon which data is printed, such as envelopes, plain paper and special paper.
memory
The part of the printer's electronic system that is used to store information (data). Some
information is fixed and is used to control how the CX6500 operates. Information that is sent to
the CX6500 from the computer is stored in memory temporary. See also RAM and ROM.
moiré
A moiré is a cross-hatch pattern that appears on scanned images when scanning printed material.
It is a result of interference that occurs due to the difference between the pitches of the scanning
and the halftone screens.
monochrome
This means printing with only one color of ink, which is generally black ink.
nozzle
Fine tubes in the print head through which ink is sprayed on the page. Print quality may decline if
the print head nozzles are clogged.
operation check
A method for checking the operation of the CX6500. When you perform an operation check, the
CX6500 prints the ROM version, code page, ink counter code, and a nozzle check pattern.
page sequence
The type of color scanning in which the entire image is scanned once for each separate color.
pixel Short for picture element. Each image is composed of a number of pixels. Pixels are also counted
in units of dots.
port An interface channel through which data is transmitted between devices.
primary colors
Basic colors. See additive primary colors and subtractive primary colors.
printable area

The area of a page on which the CX6500 can print. It is smaller than the physical size of the page
due to margins.
printer driver
A software program that sends commands for using the features of the CX6500. Often shortened
to "driver".
print queue
If the CX6500 is connected to a network, print jobs that are sent to the CX6500 while it is busy
are stored in a waiting line, or print queue, until they can be printed.
RAMRandom Access Memory. The portion of the CX6500's memory used as a buffer and for storing
user-defined characters. All data stored in RAM is lost when the CX6500 is turned off.
reset To return the CX6500 to its defaults by turning the CX6500 off and back on.
resolution
The number of dots per inch used to represent an image.
ROM
Read Only Memory. A portion of memory that can only be read and cannot be used for data
storage. ROM retains its contents when you turn off the CX6500.
RGB Red, green, and blue. These colors, in phosphors irradiated by the computer monitor's electron
gun, are used to create the additive array of screen colors.
scan An operation performed by the sensor. The image is divided into pixels by scanning.
scanning area
The physical size of the image that can be scanned by the CX6500.
spool The first step in printing, in which the printer driver converts the print data into codes that your
printer understands. This data is then sent to the printer directly or to the print server.
spool manager

The software program that converts print data into codes that the CX6500 understands. See also
spool.
sRGB
A standard color space used as the default color space within the Windows 98 color management
system (ICM 2.0).
status monitor
The software program that allows you to check the CX6500's status.
subtractive colors
Colors produced by pigments that absorb some colors of light and reflect others. See also
CMYK.
subtractive primary colors
The colors of cyan, magenta, and yellow (CMY) which produce black when mixed in certain
amounts. In printing, black is often added to give more definition as mixing of actual inks cannot
produce pure black.
threshold
A reference point that is used to determine whether data will be processed as "on" or "off". In the
case of color image data, "on" means that a certain color will appear in a pixel or dot, and "off"
means that color will not appear there.
tone correction
A method of adjusting the tone curve so that the reproduction results on different types of output
devices have gradations similar to the original image.
tone curve
The graph that shows the contrast ratio between the input (original image) and output (image
data) in image processing.
unsharp mask
Originally a photographic process in which a sharply focussed and a slightly out-of-focus image
are combined to produce a sharper image. This process is simulated by software to produce the
same effect.
USB interface
Universal Serial Bus interface. Enables the user to connect up to 127 peripheral devices (such as
keyboards, mice, and printers) to the computer through a single, general purpose port. The use of

USB hubs allows you to add additional ports. See also interface.
WYSIWIG
What-you-see-is-what-you-get. This term is used to describe printout that looks exactly like it
appears on screen.
