Please ensure that the scan bed is clean and there is no dirt stuck to the print because of static. Scan at 300 dpi for screen viewing and let us have a .tif or .jpg image. For specific image processing requirements we will come back to you if a different scan setting will be of use. Read the scanner manual for instructions or follow these directions to clean the scanner before start scanning the subject it later saves time editing the picture. The best way to keep a flatbed scanner clean is to use specialized optical-surface cleaning fluid along with an anti-static cleaning cloth. A clean, soft, lint-free cloth along with a mild glass cleaner can be used as well. Avoid paper towels they will leave dust on the glass. Do not use any type of abrasive pad, cleanser, or alcohol-based product on the glass. Do NOT spray the glass cleaner directly on the glass; this could damage the components inside the flatbed scanner. Instead, spray a small amount on the cloth. Make sure the glass is absolutely dry when finished, this avoids streaks.
