The MX421ade does the heavy lifting in your office every single day. When that base warranty expires, a single drum or fuser issue becomes a repair bill you didn't budget for. This 1-year onsite extension starts the moment your standard coverage ends and keeps a technician on call for another full year. Buy it any time before the base warranty date — no coverage gap, no 'let me check your serial number' runaround. Add to cart and lock in that extra year
