Hello, I have an Elna Q7200 machine with an automatic thread cutter. Lately the when I use the cutter, it cuts the bobbin thread so short that the thread slips down into the bobbin area. Then when I start to sew, the top thread gets wound up in a mess down in the bobbin area too. Why is the cutter cutting the bobbin thread so short, all of a sudden? (My feed dogs are up, I've checked all my threading) Thanks for any ideas!
SOURCE: tHE SEWING THREAD WILL NOT CATCH THE BOBBIN THREAD
the needle is not catching the thread on the down stroke have you got enough thread out on the bobing for the needle to catch
SOURCE: I was sewing a straight seam and all of a sudden
If you can hear a click then I'd say the needle is touching some part of the hook mechanics which could mean timing is out. However, it is possible that the bobbin case has just moved a little so as first trouble shooting steps, I'd suggest the following:
clean out the bobbin holder area as per manual (ie. remove the needle plate, bobbin, sewing foot and needle, take out the bobbin holder, clean the race area out, then put bobbin holder back in as per your manual, there is usually a stopper and knob or two red marks to line up. This is held by a magnet so it is possible to knock it out of place during a jam up.
Replace needle plate, bobbin, sewing foot and put in a new sharp needle, flat shank to the back and make sure it is fully up into the holder, thread up and very slowly using the needle up and down button, test sew a couple of stitches again.
If no stitch formation or you can definitely hear/see something touching then I'd say timing is out and no, its not something fixed yourself; best left to a trained technician.
Testimonial: "Thank you! I took it all out and found that the needle is indeed hitting where it shouldn't and had to take it in and need to borrow a machine...."

There may be threads jammed up in the bobbin holder area causing the jam. But removing the inner bobbin holder is a bit tricky if you haven't done it before. There are two little screws holding the silver inner down onto a black ceramic piece (inner guard ring), and you need to get these lined up the right way to get the bobbin holder back into position afterwards.
I would suggest that you join the Yahoo group Elna Heirlooms, then check out the files and photos loaded up by other members who work on their Elnas.
You shouldn't need to remove the feed dogs, just give them a clean with a little brush. But internally the machine may need a good clean and lube and without a service manual or good guide this can be challenging.
If you go this link http://www.arizonaexpressionz.com/elna_service_manuals.html you can down load the manual for this machine, the Star Series SU. Go to page 7 of the first part to see about removing the bobbin holder and inner guard ring.
It is a case of lining up the cut out of the black plate to the front, then putting the bobbin holder on top with the little arms facing front also, then replacing the two screws.
I'd suggest you take photos with a digital camera before you start to help you get it back in the right way.
I hope this helps you with the Supermatic, did you get the discs and accessories with it too? lovely Swiss quality machine with great stitching so if you can't get it unjammed, you may wish to find an experienced Elna Technician to take a look.

If the fly wheel is going around then the clutch isn't disengaged to wind the bobbin, you need to pull out the flywheel on your model to disengage the clutch for bobbin winding.
Take thread from thread spool across to bobbin winder thread guide, then back to bobbin and thread the tail through the hole on top of the bobbin. Place bobbin onto spindle on top of machine and then push it against the stop to engage the bobbin winding motor. HOld the thread tail up and start winding slowly until the bobbin core has been covered including the starting point. Stop and trim off the thread tail with scissors. COntinue winding bobbin and give the thread a nudge if needed to wind evening top middle and bottom of the bobbin. A good smooth wind is important. Also don't wind at full speed and keep an eye on the thread reel that the thread is coming off, you don't want it bouncing around as this will **** the thread and stretch then relax it affecting your bobbin wind.
Obviously if you know this and the bobbin winding mechanisim is just not working, then it will need a service/replacement by an Elna repair person.
