APPENDIX Symptom There are loops in the upper thread. The machine is noisy. The needle threader cannot be used. The thread tension is incorrect. The upper thread comes out of the needle when embroidering begins. The upper thread does not reach the bobbin thread when embroidering begins. Although the thread is not broken, a broken thread error occurs and the machine stops. Probable Cause Thread is not correctly threaded around upper thread tension discs. The thread quality is poor. Lint may be wound in the hook. The upper thread is not threaded correctly. The hook is damaged. Not enough oil was applied. The needle is not at the correct position. Recommended needles are not used on this machine. The needle is not installed correctly. The hook on the automatic needle-threading mechanism is bent. The upper thread is not threaded correctly. The bobbin thread is not correctly threaded. The lower thread tension is incorrect. If a short length of thread remains after the thread is trimmed, the needle may become unthreaded when embroidering begins again. There is no more thread in the bobbin, the thread does not feed from the bobbin, or the thread that is fed from the bobbin is too short. Remedy Clean upper thread tension disc. Rethread and make sure tension disc rotates when pulling on thread. Try sewing with different thread. If the problem no longer occurs after the thread is changed, the thread quality is the problem. Replace the thread with one of good quality. Clean the hook. Check the thread path, and then thread the upper thread again. Replace the hook. Consult your nearest Brother dealer. Oil recommended parts. Touch the key to move the desired needle bar to be threaded into embroidering position. Replace and use recommended needle. Correctly install the needle. Consult your nearest Brother dealer. Check the thread path, and then thread the upper thread again. Correctly thread the bobbin thread. Adjust the tension of the bobbin thread. Set the remaining length of thread to "Long Tail" on the second page of the settings screen. Correctly thread the lower thread. If the thread breakage sensor in the thread tension disc of the thread tension knobs cannot detect that the thread is being fed, even if the machine is running, a broken thread error occurs and the machine is stopped. If the thread came out of the thread tension disc, even though the thread is not broken, the machine detects that the thread is not being fed and stops. Clean the tension unit. Correctly pass the thread through the thread tension disc. If the broken thread error occurs after the machine is cleaned and rethreaded, the sensor may be damaged.
