You cannot start EPSON TWAIN.

Turn on the scanner and then turn on the computer.

Make sure the interface cable meets the requirements of your interface board. See the manual that comes with the interface board (for SCSI users).

Turn off the scanner and turn off the computer. Then check the connection between the scanner and the computer.

Make sure that EPSON TWAIN is selected in your application software.

Make sure your software is installed correctly.

For Windows 98 and 2000 users:
In the Device Manager menu, make sure your scanner's name appears under Imaging Device hardware type without a question (?) or an exclamation (!) mark. If the scanner appears with a question (?) or an exclamation (!) mark, or as an Unknown devices hardware type, click Remove to remove it while the scanner is still connected and turned on. Then reinstall EPSON TWAIN. See Recovering from Scanner Software Installation Problems on Windows 98 and 2000.

Note:

If the EPSON Scanners Driver Disk is requested during the EPSON TWAIN reinstallation, insert the Scanner Software CD in the CD-ROM drive. Be sure to specify the correct drive letter, the EPSON folder, the folder of your preferred language, and the Win98 (for Windows 98 users) or Win2000 (for Windows 2000 users) folder as the location.
