Steps if suddenly can't scan auto update Windows
Windows auto-updates often change network profiles to “Public” or reset sharing defaults, blocking scans. First, open Network Status and ensure your connection is set back to Private. Next, check your shared scan folder properties: ensure it is still shared and that “Everyone” or your specific user account has Full Control permissions. Finally, open Windows Defender Firewall and verify that “File and Printer Sharing” is allowed through. If using an FTP or SMB scanner utility, restart the service or app to refresh the connection to your Konica Minolta machine.
