The scanner does not start scanning. Problem Solution The scanner isn't ready. Check if the scanner's READY light is on. If not, press the RESET button and try again. You have a system interrupt conflict (Windows). If you have other expansion cards in your computer, make sure they're not set to the same interrupt level or I/O address as the interface card for your scanner. See your computer manual and interface card manual. Your INF file may not be loaded correctly (Windows). Use Add/Remove Programs in the Windows Control Panel to uninstall EPSON TWAIN Pro, then reinstall it. See Setting Up and Using Your Scanner for installation instructions. You're scanning a large image and running out of system memory. If the image you're scanning is too large or if your system has a minimum amount of memory installed, you may run out of memory. You'll usually get an error message or your system locks up when this happens. Reduce the image size or resolution and try scanning again. If you still can't scan the image, add more system memory. On a Macintosh, you can assign additional memory to the application itself. See your Macintosh documentation for details. If you've just scanned a large image in Photoshop® and then immediately scanned another, Photoshop may not have released the memory allocated for the first image. Select Purge in Photoshop's Edit menu, or close Photoshop, restart it, and try scanning again. You don't have enough hard disk space. Try reducing the document size, scanning fewer pages at once, or deleting unused files on your hard disk. If you're running Windows, empty your Recycle Bin. If these methods don't work, see your system documentation for more information about freeing hard disk space. Troubleshooting Page 53
