What should I do if my Brother MFC-J4320DW says 'Paper Tray not detected'?

If your Brother All in One Printer shows 'Paper Tray not detected', it means the paper tray is not completely inserted. Slowly push the paper tray completely into the machine. Also, if jammed paper or a foreign object has prevented the paper tray from being inserted properly, pull the tray out and remove any obstructions before reinserting it.
