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.
