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.
