I have the Janome 7700 and there are 3 1/4" feet that can be used. If not using the Acufeed, there are two feet to use. One with a metal guide and a clear plastic one you can use with a guide or not. If using the Acufeed, the 1/4" has a metal guide on it. When using the feet with the guide, I have to be sure not to shove the fabric up againt the guide or I don't get a true 1/4" seam.
