I have just bought a 1200D Serger and am trying to do the cover hem on a knit material. I have tried the wide and narrow with the same problems. The wrong side is just a jumbled up bunch of threads and the left needle thread keeps breaking. However, it sometimes will work ok for a few inches, (gives me some hope), then goes back to the thread breaking and jumbled up in the back. I'm pretty sure I'm threading it properly. I would appreciate any feedback on this problem. I got this machine for doing hems on knit materials and it's not working and I've been at this for 2 days!

Be sure you are threadin properly. Always start from the beginning each time you thread any serger. If a thread breaks you cannot just replace that thread, you must start from the begginning.

And re-thread in the sequence required. First lopers and then needles. Follow your manual carefully.

Thanks to all. I don't know what I did different, but I got it to work. Did a dance. I did find it worked if the stitching is going with the stretch like a hem would, and didn't work going across the stretch. I don't know. I don't think I threaded any differently, but you never know, sergers are very picky. Thanks again.

It is very important to have the left needle thread (yellow) deep in between the tension discs. Be sure to really press the thread by pulling it up and down until you feel the tension. I had the same problem and got this advice from somebody.
I got my 1200D 3 months ago and I just love it.

My 1200D recently came back from a service, so all should be ok. But I've just made two knit tops and tried to coverstitch the hems on both. In both cases, the left line of stitching skips stitches and leaves a mess underneath. I've tried rethreading, changing to new needles and even swapping the needles over, but I keep getting the same result. Does anyone have any other suggestions or help to offer?

Jen, take it back to your dealer. Take in the item you are having the problem with and show him/her. Sergers are wonderful when they are working right, but at times they can be a nightmare.

One more important thing-any time you break a thread, or needle for that matter. You've got to make sure that the needle threads are clear of the loopers(both of them if you're using two), the easiest way to do this is to sweep under the presser foot and pull them out. then pull the loopers through to the back to make sure that there are no threads hindering them. If the needles make even just one cycle, they are wrapped around the loopers and will continue to cause problems (the specific problems that you are having) Also, make sure your needles are inserted all the way up.

I recently bought the 12000D overlocker and also had trouble (a whole day!!) trying to get it to work on the coverstitch. I found turning the looper tension underneath right down worked for me...the stitches were perfect!!!
I think it is a great machine, but takes time to get used to it's ways...not just the threading up. The actual overlock stitch is very good. I have yet to try the chain stitch with the overlock and the coverstitch using spreader....haven't got the confidence for that yet!

Remember that serging is very different from cover stitching. It is a whole different process. You need to move the needles to another place for the cover stitch to work. Also you need to do something to get rid of the upper looper. I don't know on the 1200D by Janome, but I have a Husqvarna 936 and it was such a nightmare (much worse than the new serger/cover combo, mine is old technology combo), that I bought myself a retirement gift (money from work) of the CoverPro 1000. I have never regretted the purchase, as when I did use the combo machine, I would find that I would just get into the cover stitch and then need the serger - 13 things to change. The new Janome has just 3 or 4 so is much, much better.
I found that I needed to practice a bit when I go to use the cover stitch. It is good to always try a sample of what you are sewing to make sure all is working well. I personally don't find it a simple as sewing but like to have that nice hem on garments. It is a nice finish.
