I have a Janome 6500 and when I put the feed dogs down it will give me the message not as an error but shows the feed dogs down. I thought it was messed up the first time it ever did it but then I was told that when you drop the feed dogs it will give you the message again so that you are aware that you are in that mode as a reminder. I then hit the foot pedal lightly once and it clears the message and it is ready to go. Might try that or call your dealer and ask him as this is one of the new machines, but if you can drop your feed dogs you should be able to fm. Hope this made sense as this morning is a in another world day.
