Network scanner cannot deliver to a mapped network folder (scan-to-folder failure)

The problem: Scan-to-folder function fails to save scanned documents to a specified network share, though the scanner itself completes the scan.

Symptoms: Scanner control panel shows an error like unable to connect or access denied when delivering to the configured network folder; scan-to-email or scan-to-USB works fine; test scans complete but never appear in the destination folder.

Likely cause: The credentials configured on the scanner for accessing the network share have expired or changed, share permissions were modified, SMB protocol version mismatch (particularly SMB1 deprecation on newer Windows), or the destination folder path changed.
