All-in-one printer's scanner stops working after a firmware update

The problem: Following a printer firmware update, the scanning function becomes non-functional while printing continues to work correctly.

Symptoms: Print jobs process normally; attempting to scan fails to detect the scanner, returns an error, or produces completely blank/failed scan results; issue began specifically after a firmware update.

Likely cause: The firmware update altered the scanner's communication protocol, reset scanner-specific configuration, or introduced a genuine firmware bug affecting the scan function specifically.
