The short version
In Lexmark's MX43x series, from 2020, the MX431adn is the one that runs at 40 pages per minute. Also in the series (pages per minute in brackets): MX431adw (40) and MX432adwe (40). Worth knowing: it scans double sided originals in one go, up to 20 images a minute and loads 350 sheets as standard and 900 fully optioned. Lexmark still has it on its Australian list.
