Could be top thread tension is two low. Be sure stitch is centered between fabric layers. Increase tension if top thread is showing on wrong side.

Be sure stitch is in between the two fabrics when straight stitch. Adjust tension until stitch is between top and bottom fabric. Use different color top thread to make it easier to see. Once tension is correct sewing straight, switch to zigzag.

Remove hook race and bobbin. Clean area with vacuum.
Replace needle.
Try different thread and fabric.

Try reading the USB memory stick on a PC to verify it functions.

I`m confused whether you mean top bobbin or lower bobbin...You can go back to the point where it broke...Brother machines are far more simple when this happens...

What r u trying to sew? Type fabric?. Is the needle old? Is the bobbin old, chipped, dirty, set in backwards?

I did not find a specific manual for that model. Same question was asked in 2012 and 2017 without an answer on FIXYA, so it is unlikely one was readily available. Some other model manuals might be helpful to you: http://homeappliance.manualsonline.com/manuals/mfg/janome/janome_sewing_machine_product_list.html https://www.manualslib.com/manual/522797/Janome-Sewing-Machine.html There were several web sites with replacement parts, but not a manual shown using https://www.google.com to search, in case you are looking for parts.

Two things make sure your threading it in the right order. your upper looper first then your lower looper then your needles. If your doing that then change your needles and if your using cheap thread on an overlock it just wont sew right. You need to use a good quality thread on overlocks. Hope that helps

You don't lower the feed dogs on the Janome CM2200. You need the cover plate to cover the feed dogs during free-motion sewing or darning. The cover plate was included in the original accessory kit for the sewing machine. You can get a replacement from many sewing machine parts shops. One source is https://www.sewingpartsonline.com/janome-2200-sewing-machine-parts.aspx?sort.ss_cat_sort=desc&index=1 . The direct link is https://www.sewingpartsonline.com/cover-plate-janome-new-home-825018013.aspx . Some shops sell in a kit with presser feet for free-motion quilting. I hope this helps. Cindy Wells
