Scanning software problems
You cannot start Epson Scan
❏ If you are using any TWAIN-compliant program, such as Adobe Photoshop Elements, make sure
that the correct scanner is selected as the Scanner or Source setting.
❏ If you upgraded your computer’s operating system, you need to reinstall Epson Scan. Uninstall
Epson Scan as described in “Uninstalling the printer software” on page 263, then reinstall it from
the printer Software Disc.
For Windows only:
Make sure your printer’s name appears under Imaging device without a (?) or an exclamation (!) mark
in the Device Manager window. If the printer’s name appears with one of these marks or as an
Unknown device, uninstall Epson Scan as described in “Uninstalling the printer software” on page
263, then reinstall it from the printer Software Disc.
