Brother International PR1050X Operation Manual - Page 299

APPENDIX Symptom Probable Cause The needle is not at the correct position. The needle threader cannot be used. The thread tension is incorrect. Recommended needles are not used on this machine. The needle is not installed correctly. The hook on the automatic needlethreading mechanism is bent. The upper thread is not threaded correctly. The bobbin thread is not correctly threaded. The lower thread tension is incorrect. Lint or dust has accumulated in the thread tension disc. 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. 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. 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. The thread is worn. Lint or dust has accumulated in the thread tension disc. Jumpstitches are long. Lint or dust has accumulated in the thread tension disc. There are needle cuts or holes in the garment. The needle is dull. The fabric is too delicate. The thread tension is too tight. There is puckering in the fabric. The framing tension of the fabric is incorrect. The column stitches are too long. Remedy Touch the key to move the desired needle bar to be threaded into embroidering position. Reference Page p.63 Replace and use recommended needle. p.33, 86 Correctly install the needle. Consult your nearest authorized Brother dealer. Check the thread path, and then thread the upper thread again. p.33, 86 p.57 Correctly thread the bobbin thread. p.36 Adjust the tension of the bobbin thread. Remove the tension dials, and then remove any lint or dust accumulated between the felt washers. p.124 p.287 Set the remaining length of thread to "Long Tail" on the second page of the settings screen. p.228 Correctly thread the lower thread. p.36 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. Consult your nearest authorized Brother dealer. p.59, 287 Remove the tension dials, and then remove any lint or dust accumulated between the felt washers. Remove the tension dials, and then remove any lint or dust accumulated between the felt washers. Replace the needle. Dull needles have a difficult time passing through the garment, causing fabrics to tear. The simple penetration of the needle could damage delicate fabrics. Use stabilizer on top of fabric. Adjust the tension according to the type of fabric and thread being used. Polyester thread will stretch during sewing especially if the tensions are set too high. After the stitching is complete, the thread returns to its original strength, causing puckers in the fabric. Tightly frame non-stretchable, woven fabrics. Loose framing will cause the fabric to bunch up under the stitching. Tautly frame soft knits using a stable backing. Overstretching the garment will cause it to look puckered when the frame is removed. Re-digitize the design with fill stitching or with multiple rows of column stitching. p.287 p.287 p.33, 86 p.254 p.125 p.253 7 297
