Q:
Why can't I start EPSON TWAIN 5?
A:
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. For Macintosh, check the EPSON Scanner Selector. For Windows 98, check the Utility tab on the Perfection 1640SU Properties window. For Windows 95 or NT, check the EPSON TWAIN 5 window. Make sure you selected EPSON TWAIN 5 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 reference guide.
