How to troubleshoot and resolve blurry or poor quality scans from your Canon scanner


I have been using my Canon scanner for a while now, but recently I have noticed that the scanned images are not coming out as expected. Despite trying different methods to resolve the issue, such as adjusting the scanner settings, cleaning the scanner glass, and updating the scanner driver, the problem still persists. The images appear blurry or with poor quality, which is concerning since I need to scan important documents.

I am unsure what the root cause of the issue is and how to troubleshoot it. I have checked the scanner's hardware and software, but everything seems to be functioning normally. Additionally, I have reviewed the scanner manual, but it doesn't provide much guidance on how to resolve the issue.

Could the issue be related to the scanner's firmware, compatibility issues with my computer, or some other factor that I am not aware of?

I would appreciate any advice or guidance from the Canon community on how to troubleshoot and resolve this issue. Thank you in advance for your help.🙏
