I posted this question before but have not seen it on here so will try again. I just bought used Janome 7700 and it won't let the pressure foot come down to throat plate. The lever goes up two levels but at the lowest level it is way off the plate. Will not reach fabric. It runs but foot is still up too far. Any thing I am missing. I will probably bite the bullet and take it in but I hate to be told that I missed a simple step somewhere. The dual foot attachment is on it but don't see where it tells me to take it off when I am not using it. Thanks .
