APPENDIX Symptom The upper thread breaks. The bobbin thread breaks. Stitches are skipped. The embroidery pattern is misaligned. Probable Cause Adhesive is attached to the needle. The fabric is not taut. The thread quality is poor. The embroidery data contains stitches with a pitch of zero. The embroidery data contains many stitches with an extremely small pitch. The thread density of the embroidery data is too fine. Three or more overlapping stitches are being sewn. The bobbin thread is not correctly threaded. The bobbin is scratched or does not rotate smoothly. The bobbin case is damaged. The thread is tangled. A bobbin designed specifically for this machine is not used. The upper thread is not threaded correctly. The needle is bent or blunt. The needle is not installed correctly. Dust has accumulated under the needle plate or in the hook. The needle and the hook are not correctly passing each other. The thread twist is either too tight or too loose. The thread is tangled. The fabric is not secured in the embroidery frame (for example, the fabric is not taut). The embroidery frame is too large for the size of the embroidery. Stabilizer (backing) is not used. Remedy Replace the needle. Firmly set the fabric in the embroidery frame so that it is taut. The thread quality is too weak due to age of thread. Replace thread. Delete all stitches with a zero pitch. Delete all stitches with a small pitch. Using a data design system, correct the thread density and overstitching settings in the embroidery data. Correctly thread the bobbin thread. Replace the bobbin. Replace the bobbin case. Remove the thread jammed and clean the hook. Use the correct bobbin. Thread the upper thread correctly. Replace the needle with a new one. Correctly install the needle. Clean the hook and the needle plate. Consult your nearest Brother dealer. Improper twisting results in irregular loop formation. Try using a new spool. Use tweezers to remove any tangled thread from the hook. If the fabric is not taut, the pattern may become misaligned or the stitching may shrink. Be sure to correctly frame the fabric in the embroidery frame. Use an embroidery frame that is close to the size of the embroidery. Use stabilizer (backing) when embroidering on thin or stretch fabrics, fabrics with a coarse weave or fabrics that easily allow the stitching to shrink. Use hard stabilizer when embroidering on a cap made of soft material. Reference Page p.88 p.49, 94 p.226 p.226 p.150 p.38 p.38 p.38 p.282 p.35 p.56 p.35, 88 p.88 p.282, 283 p.49, 94 p.90 p.93 294
