How do I fix 'Wrong Paper Size' error on my Brother MFC-J450DW All in One Printer?

The Paper Size setting doesn't match the paper in the tray, or the paper guides aren't set correctly. Check that the paper size you choose matches the size of paper in the tray and that you loaded the paper in a Portrait position, setting the paper guides at the indicators for your paper size. After checking, press Black Start or Color Start.
