Why does my scanner output distorted pictures?

When a scanner produces distorted images, it can be caused by a few different issues.

1. Resolution: The resolution of the scanner can affect the quality of the output, so if the scanner is set too low, the image will appear distorted. Additionally, if the image resolution is not matched to the resolution of the scanner, it will likely look distorted.

2. Illumination: Scanners rely on optimal illumination levels to capture the appropriate colors and contrast in an image. If the illumination levels are too low, the colors will be dull and the details will be washed out. Similarly, if the illumination levels are too high, the colors may appear oversaturated and distorted.

3. Dust or dirt: If the scanner’s glass plate is dirty, it can interfere with the light from the scanning device, creating distortions in the output image.

4. Poor alignment: The scanner’s hardware components need to be properly aligned for it to provide accurate scanning results. If the hardware is misaligned, then there will be distortion in the output.

5. Software problems: Issues with the scanner software can also cause distortions in the scanned images. For example, if the driver is not updated or incompatible with the current operating system, or if there are settings and preferences that aren’t configured properly.

In order to fix these issues, you need to check and adjust the resolution, illumination, and alignment of the scanner. Make sure the scanner’s glass plate is clean, and do a thorough scan of your computer to make sure there isn’t any infected software. You should also update the scanner’s driver to the latest version. With these steps, you should be able to correct the distorted images produced by your scanner.
