IMPORTANT
For SCSI interface users: if you are using other
SCSI devices besides the scanner, see page 2-6
and 2-7 in the TWAIN manual and also see the
SCSI information in the README file on the disk.
The colors in scan previews are not accurate if
your computer supports 256 or fewer colors. This
does not affect the final scan. For optimum
viewing choose True Color as the SCAN MODE on
the Scanner Control screen. For the best
scanning and viewing, Epson recommends using
a True Color (24-bit) video board.
Both the horizontal and vertical dimensions of
the largest scan possible are reduced by 1/2 inch
in the current version of the Epson TWAIN.
Picture Publisher must be set up the first time
you use it. Use the SETUP command in the FILE
pull-down menu. Select ACQUIRE DEVICE and
then select EPSON SCANNERS. To scan a
document, use the ACQUIRE command also
located in the FILE pull-down menu. Do not use
the SCAN command in the FILE pull-down menu
because it does not use Epson TWAIN and it may
lock up your system.
The current version of Picture Publisher (version
3.1) produces a reversed or negative image when
you use the black & white line art setting within
the SCAN MODE. Correct this within Picture
Publisher by selecting the INVERT command
from within the EFFECTS pull-down menu. This
problem will be corrected in later releases of
Picture Publisher.
The current version of Epson TWAIN does not
support all OS/2 version 2.0 applications.

the application you are currently using. For instance, suppose
you are using Picture Published and want to include a scanned
photograph. Without leaving Picture Publisher, you can use
TWAIN to scan the image and place it in your document.

your Epson scanner’s advanced features with any software
application that supports TWAIN, providing you with a
sophisticated, high-speed scanning solution.
