I posted several weeks ago because my brand new Janome 7700 jammed so badly that it damaged the bobbin case. The out come is, the dealer took it in and their tech replaced the entire bobbin case area, and retimed the machine.
It is sewing and sounding better then when it came out of the box. My thinking is it was not set in correctly to begin with.
I am loving this machine again.
I can not emphsize enough the value of a good honest dealer who is really intereted in having a happy customer.
