I have a single head 15 needle Tajima machine that is having a thread cut issue during a thread change. I was able to get the majority of the image to stitch out. After each thread cut/needle change the new needle does not pick up the bobbin thread. I have to stop the machine remove the bobbin, pull out a some thread and put it back it in. When i do that and start the stitching it does work. Any idea how to correct this? I am wondering if i need to adjust the thread trim.
