I have a Janome 6600 (have had it for two years) and have never had a problem. All of a sudden this afternoon I started having a problem with it feeding the fabric. I am only sewing two layers of cotton (foundation and strips). All of a sudden the feed dogs were down and I couldn't get them back up. After playing with the lever on the under side....moving it back and forth many times....the feed dogs came up but then they go back down in a little bit they go back down. I have tried everything from changing needle, bobbin, rethreading, etc. etc.
Does anyone have any idea what the problem could be. And of all times, I am supposed to leave Wed afternoon for a four day quilt retreat. I need help.
Thanks for looking. Pat
