Welcome to Cute.
I have a Janome 300E. I had trouble with my machine all day yesterday. Have you changed the thread - not just the spool but kind. I was using poly and when I finshed working on everything. When I got it all tweeked, rayon will sew. I will try poly later tonight. If I can help you - I will try.
Just let me know.

Welcome sweetie. I don't know anything a Janome machines either, but surly someone will. Call your dealer if you can not remedy it. You spent to much money for them not to help you.

was wondering if your problem has been solved? *4u all

Sorry to hear about your machinetroubles, if you cannot solve this problem ask your dealer. Welcome to this CUTE site and hope you will enjoy this site and community.

Could be: 1)type of thread, 2)if pre-wound bobbin too big, just cut off about 3 yards and try again, 3)a burr on the "finger" aka (little arm). Slowly run your finger over it and see if anything "sticks" you. If so, use a very fine sand paper and gently smooth it off.;)

I always have funny problems with my 9700 too. Driving me nuts. a 10mins embroidery can end up 1hr. OMG

I have face problems of big machine jam sound at bobbin case area. Then the fabrics will have threads jammed up at the base of the fabric.

I have tried

1-clean the bobbin case area (taking out the metal plate etc),

2-Rethread (sometimes its not hooked well),

3-Change bobbin case (this solve most of my problems),

4-check the foot/needle etc if tight.

I can tell u i have done soooo many times, then i faced the same problems until i redo it again n again (those points mentioned) n get things done. ARGK

another thing is i was told by the sales assistant to put the bobbin thread direction as anti clockwise into the bobbin area. When I have threads problem, i will pull out a lot till the screen there n let it slowly use up during sewing/embroidery.

I have found to only use Janome bobbin cotton as the tension is set for it. This has helped with most problems in my Janome 9700. I also let it cool down every couple of hrs. I take a walk in my garden,have a coffie then restart. Happy embroidering *4U

Sometimes changing thread will work too.(different brand)And in bobbin too.
