There are a variety of reasons why a scanner may produce fuzzy or illegible images. The most common causes of this issue include:
1. Low Resolution: Most scanners have an adjustable resolution setting which determines how large an image will be and how much detail it can capture. If the resolution is set too low, the scanned image will appear fuzzy or grainy.
2. Wrong Scanning Mode: Different types of images require different scanning modes in order to be scanned correctly. For example, if you are scanning a photograph, select the “Photo” scanning mode in the scanner’s settings rather than the “Text” mode.
3. Dirty Scanner Glass: If there is dust or debris on the scanner glass, it can affect the quality of the scanned image. It is important to keep the glass clean and free from dirt and fingerprints.
4. Poor Lighting: If the item being scanned is not lit properly, it can cause the scanned image to be fuzzy or illegible. Make sure the item is evenly lit and that all edges are visible.
5. Wrong Scanner Settings: Scanners come with various settings, such as brightness, contrast, and color balance. If these settings are not adjusted correctly, they can cause the image to appear fuzzy or distorted.
6. Old Scanner Software: Many scanners come with outdated software that may not be compatible with newer operating systems or image formats. Updating the scanner software may be required in order to obtain better image quality.
7. Low Quality Scanner: Some scanners are simply not up to the task of producing quality images. These models tend to be very low cost and may be limited in terms of features and capabilities. Investing in a higher quality scanner may be necessary in order to obtain clear, crisp scanned images.
