Hi
I couldn't find a manual on the Janome site for the machine you have but I did find this one for a similar looking machine. It should be enough to get your started on how to thread your machine and what the different parts are for.

Janome has an even feed foot for their machines. Any janome dealer should carry them.

If the top thread looks normal and the bottom thread "loops", it means that the top thread does not have tension. Take out all the thread and re-thread the path, giving special attention to the path of the thread through the tension disks.
Thread the machine with the sewing foot up, it opens up the tension disks, and make sure you lower the foot before sewing.
This will close the tension disks.

I've always been able to get a free PDF downloadable manual from Janome. They are happy to send you a manual for your specific machine via email, and they've always been very helpful to me. Here's a link to them:
