Does anyone know how to fix and or clear error code 3A6 on a Tajima TMFX II machine? We had a needle break and now we are receiving the error. We do not have any birds nests or broken bits of knives. We've also checked to make sure the knives are not stuck in either the open or closed position. Any help would be greatly appreciated. Tried fixing this problem until 10:30 the other night with no success.
