Connecting the Scanner to Your Computer
For PC users:
Unless your PC already has a SCSI board installed, you need to
install one, along with SCSI driver softwar e. Install the SCSI board
according to the directions included with the board. Also see
"Installing a SCSI Interf ace Board (Windows Only)" on page 1-6.
If your PC has a SCSI board up and ru nning, connect t he scanner
as described in the next section.
Note:
You will need to install the SCSI driver that is normally included with
Windows 95, 98, or NT (see yo ur sy stem d ocumentation for
instructions), or the dr iv er d escri bed in the SCSI board installat ion
documentation.

Setting Up the Scanner
Understanding SCSI connections
Read the following sections to determine how to set up your SCSI
devices and whether you need any optional SCSI cables.
Daisy chain
The SCSI interface allows you to connect up to seven devices (such
as a scanner, hard disk, CD-ROM, and so on) to the computer, in what
is called a “daisy chain” arr angement. Only the first SCSI device in
a daisy chain is connected to the c omputer; eac h of the o ther devi ces
is connected to another SCSI device.
SCSI cables
You may need to purchase SCSI cab les be fore set ting u p y our SCSI
daisy chain. Be sure the SCSI cable connectors are suitable for your
hardware, depending on the maker of your SCSI devic e and SCSI
interface board.
1
SCSI ID and t ermi nator
Each device has a SCSI ID number : the computer is usually
number 7, and each of the other devices must have a different
number between 0 and 6. Also, the first device and the last device
in the chain (not including the computer) must have a terminator.
No other device can have a terminator, or if a terminator does
exist, it must be turned off or removed.

Using Your Scanner
Sizing Up Your System
Your scan ner is suff ic ient fo r mos t scan ning needs , but if you a re
not satisified with the quality of the images on your monitor or
with the speed of image processing, read this section. While it
does not contain specific recommendations, it describes various
possibilities for improving your scanning system. For further
information, seek advice from your dealer or an experienced
scanner us er.
RAM and hard disk size
Scanned images use much more memory than tex t fi les, so
you may ne e d more RAM (Ran dom Access Mem ory) in your
computer and a larger hard disk than you have used previously.
Accelerator boards
In addition to memory, processing speed is importan t because
large files take longer to process than small ones. Therefore, y ou
may want to add an accelerator boa rd to your co mputer.
2
Video cards
A video card that is sufficient for text may not be good enough
for displaying graphic images, especially in color. If all your
scanned images look coarse on your monitor, you may want to
upgrade your video card. You will need 24-bit c olor, also called
true color or mi llions of colors, to make the highest q uality im age
reproductions.
Using Your Scanner
2-9
Monitors
The resolution of your monitor affects t he quality of the image
you see. Consider a high resolution monitor if you do precise color
work, but also be sure you have a high quality video ca rd.
File compression software
Many different programs are available to make image files
smaller for storage or transmission. For example, some
compression software c an store a 3MB image file on a 1.44MB
floppy disk, an d co mpress i mages and r es tore t h em with no los s
of data or quality; others compress images more , but the restored
file is not exactly the same as the original. The difference between
the original and restored files is, however, almost unnoticeable.

Glossary
line sequence
A type of color scanning that separates primary colors line by line. The carriage
makes only one pass.
monochrome
Black and white images, or images represented only by the intensity of
luminosity.
OCR
Optical Character Recognition. The technology that allows computers to "read"
text from physical objects. OCR requires a graphical representation of text to
interpre t, which usually comes from a scanned im age.
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 c ounted in units of dots.
plain bi-lev e l
Bi-level image data without the halftoning process.
port
An interface channel through which data is transmitted between d evices.
primary colors
Basic colors. See
addi tive p rimary colors
subtractive primary col ors.
and
resolution
Indication of how finely an image is resolved into pixels. Measured in dots per
inch (dpi), pixels per inch (ppi), or samp le s per inch (spi).
scan
An operation performed by the sensor and the carriage. The image is divided
into pix els by scanning.
scanning area
The physical size of the image that can be scanned by the scanner.
SCSI
Small Computer System Interface. This is one method used to connect your
computer to peripherals such as scanners, hard disk drives, CD-ROM drives, and
others.
SCSI ID
The numbers that all devices in a SCSI connection (see
each other. If the same ID number is used by two devices in the same daisy chain,
the devices cannot operate properly.
daisy chain
) use to identify

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.
terminator
A device that stops electronic signals, and prevents them from proceeding or
returning to other devices. This is necessary to stop a signal from continuously
bouncing between devices.
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 colo r 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.
