Home Support Scanners Expression Series Epson Expression 1680

I can't start Epson TWAIN. What should I do?

  • Make sure the scanner's READY light is on. Check to make sure your cable is securely connected to both the scanner and computer. Try a different cable. If you have a USB connection, be sure to use an EPSON USB cable. If you have a SCSI connection, try using an ASPI-compliant Adaptec SCSI 2 cable, and be sure to restart your computer after you change the cable. If you have a SCSI connection, you can't turn the scanner off and on again while you're using your computer. Turn both the scanner and computer off, then turn on the scanner before you turn on the computer. Make sure the SCSI interface board is installed correctly in your computer. Check that your system recognizes your scanner and SCSI board (Windows only). Check the System Device Manager in the Windows Control Panel. For Windows NT, check the SCSI Adapters dialog in the Windows Control Panel. Check for conflicts in your SCSI ID setting, I/O address, the interrupt setting for your SCSI board, and other settings. For information about the SCSI ID setting, see Connecting to a SCSI Interface in your User's Manual. For information about choosing other settings, see your computer manual. If your computer has the scan server loaded at startup then TWAIN Pro cannot be used, TWAIN Pro Network must be used. If you have more than one scanner connected to your computer, make sure the Expression 1680 is selected as your default scanner. For Macintosh, check the EPSON Scanner Selector from the Apple menu. For Windows 98, check the Utility tab on the Expression 1680 Properties window in Control Panel. For Windows 95 or NT, check the EPSON TWAIN Pro window in Control Panel. Make sure you selected EPSON TWAIN Pro as your TWAIN source. If you have an older EPSON scanner and have a previous version of EPSON TWAIN installed, uninstall the older version (Windows) or close any extensions like EPSON Scanner Monitor, EPSON Scanner Monitor USB, or EPSON Monitor 3 (Macintosh). If none of these solutions help, uninstall your software, then reinstall it. See the instructions for uninstalling software in your user's manual.
