What does 'Size Error DX' mean on my Brother MFC-7360N All in One Printer?

If your Brother All in One Printer displays 'Size Error DX', it means the paper in the tray is not a suitable size for automatic duplex printing. Load either Letter, Legal or Folio paper for automatic duplex printing, and then press Start.
