You've got the Advanced Exchange base warranty on your MX431adn. That means if it breaks, the unit gets swapped — fine, but you lose a day or two waiting for the replacement to land. This upgrade changes how the fix happens: a technician comes to your site and repairs the printer in place. Same coverage window you already have, different (faster) outcome. You keep printing while they work
