I just got a Janome 3160 QDC and so far I am trying to sew without the pressure foot. Wow that is a hard thing to get used to..already I got excited about stopping the machine and I now have an icon that says I have a thread jam. I have looked at all possibilities and that darn icon is still there. I hesitate continue to sew with the icon showing...will have to call shop for help. But it is the way to go...no more fighting with the foot pedal!!
