Scanning Color Images

If the colors in your scanned image don't match those in your

original document, try experimenting with the Unsharp

Mask setting. Click the Destination button in the EPSON

TWAIN Pro main window to display the Destination

window, and then select or deselect Unsharp Mask.

Selecting Resolution

Resolution refers to how many dots per inch (dpi) or dots per

centimeter (dpcm) your image contains. The best resolution

for a scanned image depends on the type of image you're

scanning and your final output device.

As a rule of thumb for most images except line art, use a

scanning resolution that is approximately one third of your

output resolution. For example, use a scanning resolution up

to 100 dpi with a 300 dpi laser printer, and up to 200 dpi

with a 600 dpi laser printer. For 1440 dpi ink jet printers,

such as the EPSON Stylus

resolution of up to 300 dpi. Try a scanning resolution of

240 dpi for 720 dpi printing.

Keep the following in mind when you choose a resolution:

The higher the resolution you select, the larger the resulting

image file will be. For example, an 8.5

scanned at 300 dpi can produce a 24MB file. The same

original scanned at 72 dpi creates only a 1.3MB file. Large

files take longer to process and print, so consider the

practical limitations of your computer system and hard disk

drive when selecting a resolution. To keep your file size

manageable, select the lowest possible resolution that gives

acceptable quality. (If your final output is for on-screen

viewing, you can scan at 72 dpi and reduce your file size.)

If you need to scan at a higher resolution, you can reduce

the size of the resulting image file by scanning only part of

the image. For information about selecting part of an image,

see "Making and modifying marquees" in your electronic

EPSON TWAIN User's Guide.

Using a Network Scanner

Network scanning involves the following steps:

The scanner server must be turned on and running EPSON

Scan Server.

From the client computer, start EPSON TWAIN Pro

Network to establish a connection to the scanner server.

Only one client computer at a time can connect to the

scanner server. (See "Starting EPSON TWAIN Pro

Network" on page 7 for instructions.)

Choose the Image Type, Resolution, and other settings

you want for your scan.

Place your first image on the document table (or in the

optional automatic document feeder or one of the optional

transparency unit's film guides).

Start the scan. Although this can be done from EPSON

TWAIN Pro Network on the client computer, it may be

more convenient to press the scanner's ] Start button or to

start the scan from the scanner server. Then you can scan

several images with a single trip to the scanner.

If you want to scan more than one image, place your second

image on the document table and press the scanner's

] Start button again. Repeat this step for every image you

want to scan. (The settings you chose for the first image

apply to these images too.)

When you return to the client computer, your scanned

images appear in the host application's window. Close

EPSON TWAIN Pro Network to end your connection to

the scanner server and allow other client computers to use

the scanner.

Some applications, such as Adobe Photoshop LE,

automatically close the client computer's connection to

the scanner server when you press the ] Start button.

You can't use the ] Start button to scan multiple images

if you're using these applications.

Starting EPSON Scan Server

EPSON Scan Server starts automatically whenever the scanner

server is turned on. When EPSON Scan Server is running,

you'll see either the EPSON Scan Server dialog box, or the

EPSON Scan Server icon

need to start EPSON Scan Server manually, click Start,

Programs, EPSON Scan Server, and then select EPSON

Scan Server.
