Canon 3in1 Printer (needs repair) (Brighton, BN2)

A PIXMA MX475 wireless Printer, Scanner & Copier all in one. Was wondering just fine until a few days ago when a stuck, misfed paper caused a malfunction with a small piece from the interior coming off. Needed to replace the unit as I don't know how to fix it. But for anyone who does, it's probably going to be not too difficult
