If you have already downloaded and installed the MF Scan Utility software let's perform the below steps to scan:
1. Open the Windows Desktop.
2. Right click on the MF Scan Utility icon and click Properties.
3. Click the Compatibility tab, then click "Change settings for all users".
4. Put a check next to "Run this program as an administrator", then click Apply and OK.
5. Open the MF Scan Utility software and attempt a scan at this point.
