This is what I have to do with my Babylock auto threader: Make sure needle is inserted correctly. The reset button also moves my needle over to the center. If yours is 'off', make sure to reset the needle. The thread size has to work with the size of needle you are using. Press needle position button to raise the needle. ( I make sure the hand-wheel has the markings lined up, then press the button.) Make sure the thread is threaded correctly. The thread should always unwind from the spool from the front of the spool. Press the auto threading button. The presser foot will automatically lower. I also have to make sure the presser foot is not set to pivot. There are times I have had to set the presser foot in the down position before the threading will work. Giving the threading hook a little nudge sometimes works too as I know I have accidentally bumped it when replacing needles or presser feet. Needle Centered, Needle Up, Presser Foot Down.
