The 'knotting up' can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your projects). IS YOUR NEEDLE SHARP?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one! TOP TENSION & GUIDES: Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp. It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically. If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread. Now, with a 2' (50mm) wide strip piece of fabric 8 - 10' (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with a see saw / to and fro action. In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to disengage tension plates). Do not gouge or score the plates, they need a polished surface to work correctly.
BOBBIN TENSION: Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a 'false' tension. I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean the hook race area (where bobbin case sits).this is just good housekeeping, my wife does this every time she replaces the bobbin. Just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint.
If there is a significant amount of lint, use a vacuum and small brush to get the worst. Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits.oil and lint combine to conspire against you. If it seems likely that you.really.do.actually.need.to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned. TOP LOADER: Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork.the other screw at one end is holding it all together, so beware.it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out! FINISHING UP GETTING THE BALANCE RIGHT: When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.
Try using good quality thread of contrasting colours so you can more easily spot the changes. Sew a sample for a few inches and check the result.
Adjust the bobbin tension screw very little at a time, perhaps 1/16 of a turn. Janome/getting-that- embroidery-design-to-y.

That said, it seems likely gearing has been damaged. Without a workshop manual, even if you found the gear, you do not know the identification number for it. I see no authentic download of the workshop manual on the web for this Memory 9500.
I only find the Instruction manual available on the web (freely available at the Janome site). Even if you find a Janome technician on an answer site, that is not going to get you disassembling the machine, replacing the part, reassembling it, and adjusting it.
Check Janome support and see what they offer: tech advice, workshop manual for sale, and/or parts. You are likely to conclude you need to find someone at a service center. Here are some links: (hardcopy, some parts) There is only one reference to the 9500 on the page.
