I have a Janome 4900Qc which has the sign Stop for Safety Purposes, this comes up really often, it has been back and been checked but no better now
Are you having thread jamming problems before you get this message?
I found that my bobbin holder which is held by magnets was being dislodged when I had a thread jam up, usually when I was trying to sew something very thick over a seam such as jeans hems.
Have you mastered removing the needle plate and the bobbin holder to clean in under it and putting this all back together again? With my 6500P, the needle had been striking the bobbin holder when it dislodged and rotated out of postion, the bobbin case had holes and damage to the plastic which was then catching the thread as the bobbin rotated making the jams happen.
Each time, I would dismantle the bobbin holder, clean everything, cut the jammed up threads, check the bobbin case and give the damaged bit a file with a nail file to make it smooth again, then put it back matching the red markings on the bobbin holder and the stopper, rethread and start over. I have bought two new bobbin cases too and taken it back to the dealer a couple of times over 5 years.
I've now learnt to not try to stitch over the thick seam intersections, I'll stop before, lift the pressure foot, move the work past the seam, then restart sewing. However, my machine was just serviced last week and it looks to me like the mechanic has added a part to hold the bobbin case in better, its like a little black lug on the left screwed into the outer housing. So perhaps Janome have addressed this issue with an aftermarket repair.
Apologies if this is telling stuff you already knew, good luck.
