Troubleshooting 6-7
The application software displays an error message, freezes, or fails
after scanning.
Make sure you close the TWAIN screen before switching to your
application software. (Do not use the Windows Minimize
button.)
The image you scanned may be oversized. Try reducing its file
size by changing its resolution or dimensions; then scan it again.
If you selected 16 Gray as the Pixel Depth setting, change to 256
Gray and try scanning again.
If you scanned an image at high resolution (such as 800 dpi) and
at the maximum allowable width and using the Color Photo
Image Type setting, restart Windows and reduce the resolution
and the width of the scanned image. Then try scanning again.
If your application contains a scan manager feature, you may
have closed it before closing the EPSON TWAIN screen. Scan
your image again, but close the TWAIN screen before closing
your application’s scan manager.
If you selected three-pass scanning on the TWAIN screen, you
may need to free some space on your hard disk to scan.
After scanning with an image editing application, the scanned image
disappears.
Make sure you close the TWAIN screen before switching to your
application software. (Do not use the Windows Minimize
button.)
