I have 2 Janome's,and I have had the same problem with both.I have the quilters companion and the Horizon.The horizon is back in the shop for the 2nd time in a month and the machine is less than a year old.I am so mad I could spit nails.I found a nic on the QC and filed it out but it still jumps out occ.I have been oiling it but I will try to do that on a sch. and see if it makes a difference.Wish I could help but it is nice to know it is not operator error since others are having the same problem.
