This may prevent the original from laying flat on the scanner glass. • Do not move your original or your product during scanning. • Clean the scanner glass and the ADF and remove and dirt or dust on your originals. • Do not press on the document cover or the original with too much force. • Your product will not operate properly while tilted at an angle. Place your product on a flat, stable surface that extends beyond its base in all directions. • Adjust these Epson Scan 2 or Epson ScanSmart settings (if available) and try scanning again: • Make sure you select the correct Image Type for your original. • Increase the Resolution setting. • If the Image Type setting is Black & White, adjust the Threshold setting. (The Image Option must be set to None or Color Enhance.) • If the Image Type setting is Color or Grayscale, select the Unsharp Mask setting. • If the Image Type setting is Black & White, select Text Enhancement. If the Image Type setting is Color or Grayscale, change the Text Enhancement setting to High. Image is Too Dark • Make sure you select the correct Image Type for your original. • If the Image Type is set to Color or Grayscale, adjust the Brightness setting. • Check the brightness and contrast settings of your computer monitor. 324
