Use it all the time. Beats stressing my old eyes.

Thank you for bringing up this subject! Sometimes mine works, sometimes it doesn't. I was extremely comforted by the fact that others too have the problems I do with mine. I am sure it is operator error now. I will However check all the little things to make sure they are not bent, then I will follow the process already stated so clearly and practice practice practice. Thanks again!

I also use mine all the time!

I have a Janome MC6500P and have never been able to master that darn threader! So, I always thread by hand...to frustrating to try..try..try..with no success!!

I have a Brother sewing machine and Janome embroidery and Love/LOVE the auto-threader on both.
Check to see if the little hook that goes through the needle eye to grab the thread is actually going through the eye. (Mine has occasionally gotten bent so is out of alignment and then doesn't work. In that situation I just gently slide my thumb nail next to the hook and re-align it.)

I use mine on the Bernina all the time. The one on my Elna is very good. I have a small Janome 3160 QDC, I love the machine's sewing, BUT the automatic threader is a pain, it doesn't work well, and this past week it actually fell off the machine! I put it back, but am thinking of just ditching it.
The size of the machine needle hole is also important. Hard to work with a tiny hole!!
I want a machine that REALLY automatically threads the machine....and then automatically sews my piecing,...and....and ............aha......what a dreamer!

You probably have bent the little thing a ma jig inside the treader. I have done that twice now on my new machine. The old one still works good. I can still see the hole in the needle so I do it that way on the new machine. Jan

My new Singer Simple has that auto needle threader and it really does not work that well. I have not gotton it to work only 1 time out of ten. It is just faster to thread it my self.

I use mine all the time but there no doubt is some small thing you are doing wrong.

I have one and lovvvvvvvvvvvvvvvveeeee it. I had to have someone show me how to do it and then it was like magic...can't live without it now. Just wait till you get the hang of it and you will love it too.
