Symptom The embroidery pattern is misaligned. The size of the installed embroidery frame is not correctly detected. The starting position for the embroidery frame is horizontally misaligned. Probable Cause The carriage moved while removing embroidery frame. The design was not digitized correctly. The thumbscrews on the embroidery frame holder are loose. Remedy The pattern may become misaligned if the presser foot was hit or the carriage was moved while replacing bobbin thread, changing needle, or working near embroidery frame. Be careful when removing and reattaching the embroidery frame while replacing bobbin thread, changing needle, or working near embroidery frame. If the carriage is moved, turn the machine off, then on again. The correct frame position at the time that the machine was stopped is stored in the machine's memory, and the embroidery frame is returned to the correct position. The design may need more pull compensation or underlay to accommodate stretchy or high-napped fabrics. Use the included disc-shaped screwdriver to firmly tighten the thumbscrews. Reference Page p.30 The thumbscrews on the embroidery frame holder are loose. Use the included disc-shaped screwdriver to firmly tighten the thumbscrews. p.30 The upper thread tension is low. After passing the upper thread through the hole in the presser foot, pull the thread by hand to check the thread tension. If it is difficult to determine, compare it with other needle bars where looping does not occur. p.125 There are loops in the upper thread. The machine is noisy. The thread tension does not correspond to the amount that the thread tension knob was tightened. 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. If the thread tension cannot be adjusted, thread wax and dust may have collected in the upper or middle thread guide plates, causing the thread tension guide plates to rise. Clean the thread tension guide plates. 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 authorized Brother dealer. Oil recommended parts. p.287 p.287 p.284 p.57 p.288 296
