Anyone have this happen?? My machine is brand new !

I hope someone can answer me. <gulp> I've been quilting my first big quilt on my Juki TLQ98E; it seems to be leaving a fine layer of black oil/dust when I run in on a fast speed. I thought maybe I had to much pressure on the presser foot but that didn't help, then I cleaned everything (again), oiled it (again) and in general spent about an hour trying to clear this up. I'm doing straight lines up and down so it would be great if I can go a little faster than normal...but you can imagine my horror when I look to a thin spatter of oily black "stuff" when I'm done. Some of it comes off when I use the sticky roller, but I'm really hoping that it will come out when I wash it.

Anyway, has anyone ever had this happen and what did they do? It doesn't say anything about this kind of problem in the manuel and I looked online (Goggled the problem) and I didn't find anyone having that problem either. A sincere thank you to anyone who knows what I'm doing wrong. I am new to this machine (I LOVE it by the way) so it I'm hoping it's just "me" and not the machine. ~LOL~

my brand new Juki is doing the same thing!! Anyone find an answer to this problem??

You are using sewing machine oil, aren't you? It should he either clear or a light golden color. Always run a scrap piece of fabric immediately after oiling for a minute or two to help catch any splatter. Don't over oil.

I'm betting it is not an oil problem. I had the same problem over a year ago when my 2010q was brand new. Lots of people apparently experienced the same thing. I contacted Juki USA in Florida and verified my serial number and purchase date and they sent a new walking foot covered under warranty. It seems there was a batch of walking feet that were faulty and they had replaced many. Give them a call and I'm sure they will rectify the problem.

Cheers!

it’s brand new - I haven’t had to oil it yet—I just started sewing on it and it was doing this.
should I oil again?( it would have come oiled though? And I’ve maybe sewn a couple hours worth tops)

We're you using a walking foot. If yes, take previous advice and ask for a new walking foot. Sounds like that is the problem.

Until you know what that balck stuff is, I woud remove all the black stuff from the quilt before washing. Those tiny little things may bleed, stain, even melt in the dryer.

I was going to suggest it could be carbon dust from motor brushes that need to be replaced. But, after reading all the posts, it sounds like it's a walking foot issue. I have the 2010Q and don't use a walking foot ever, because it's too noisy. So maybe that's why I haven't had this problem.

One of my FMQ feet was really noisy. I couldn't figure out what was wrong. I'd just had the machine serviced and it wasn't noisy with the straight stitch foot on. Turns out the FMQ foot needed oiling. Nice and quiet now.

I only used the walking foot for my 2200 QVP Mini (2010 equivalent) once and wasn't really a fan. I got the machine mostly to FMQ and I think I'll stick with that.

found out it’s the walking foot— they’re replacing it 😊
