If you are getting blurry images from your scanner, there are a few troubleshooting steps you can take to try and fix the issue.
1. Check Your Scanner Resolution
The first step is to check the scanner resolution settings. Most scanners come with different resolution settings, with higher resolution settings resulting in higher quality scans. Depending on the type of items you are scanning, you may need to select a higher resolution setting. For instance, if you are scanning photographs you will usually achieve better results by selecting a higher resolution setting.
2. Make sure the scanner is installed properly
If the resolution settings are correct, then the next step is to check that the scanner is installed properly. In most cases, this means making sure that the software used to control the scanner is up-to-date and installed correctly. Additionally, always use the recommended USB cable for your scanner and verify that it is connected properly.
3. Clean the scanner glass
If the above steps do not fix the problem, then it is likely that the scanner glass needs to be cleaned. Over time dust and dirt can accumulate on the scanner’s glass surface and can cause blurry images. You should never use any chemical solutions or abrasive materials on the scanner glass. Instead, use a soft, lint-free cloth to gently remove any dirt or dust from the scanner glass. It is also a good idea to make sure the surface is free of fingerprints, as this can also cause blurry images.
4. Check scanner settings
Finally, it is worth checking any other settings on the scanner. This usually involves taking a look at the image adjustments such as brightness, contrast and saturation. Make sure these are all set correctly for the items you are scanning. If any of these adjustments are too high or low, it can result in blurry images.
If you have gone through all of the above steps and still cannot get clear scans, then you may need to contact the manufacturer of your scanner to troubleshoot further. If the scanner is still under warranty, you may be able to get it serviced or replaced free of charge.
