Connect the scanner directly to the computer’s USB port or through one USB hub only. The scanner may not work properly when connected to the computer through more than one USB hub.
Make sure your computer supports USB. See Checking For Windows USB Support for instructions.
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 Your Scanning Software, then reinstall it as described in the Start Here sheet.
For Windows only:
Make sure the scanner’s SCSI ID and terminator are set correctly. See Setting Up the SCSI Interface for details on making these settings. If you have other expansion boards in your computer, make sure that their interrupt settings are not interfering with your SCSI board. See your computer’s documentation for details.
Make sure the SCSI cable meets the requirements of your SCSI board. Refer to the documentation that comes with the interface board.
Make sure the SCSI interface board is installed correctly.
Change the scanner’s SCSI ID number to one that is not being used by any other SCSI device.
Check the SCSI connection sequence and make sure the terminator switch of the end of device of daisy chain is set correctly.
Make sure your scanner’s name appears under Imaging devices without a (?) or an exclamation (!) mark in the Device Manager window. If the scanner’s name appears with one of these marks or as an Unknown device, uninstall Epson Scan as described in Uninstalling Your Scanning Software, then reinstall it as described in the Start Here sheet.
