    What to do if my Brother T-8722C is skipping stitches?

      If your Brother Sewing Machine is skipping stitches, check the following: Replace the needle if the needle tip is bent or broken. Make sure the needle is properly installed and the machine is correctly threaded. Adjust the presser foot pressure if it is too weak. If the needle is too thin, replace it with a slightly thicker one. Adjust the height of the presser foot if it is too high. Adjust the tension of the thread take-up spring if it is too weak, and adjust the thread take-up amount if it is too large.

    How to fix upper and lower thread not tight on Brother T-8722C Sewing Machine?
    • A
      Amanda WhitakerAug 21, 2025
      If the upper or lower thread is not tight on your Brother Sewing Machine, take these steps: First, ensure the thread is threaded correctly. If not, re-thread it properly. Next, adjust the upper and lower thread tension if they are too weak. If the thread take-up spring operating range is too small, lower the position of the stopper. If you're using a sewing machine with medium-weight material specifications, try replacing the presser foot with one that has slots on the underside, or replace the feed dog with a grooved feed dog.

    Why is there excessive tension (puckering) in my Brother T-8722C Sewing Machine seams?
    • P
      Paul CunninghamAug 25, 2025
      Excessive tension or puckering in your Brother Sewing Machine seams can occur for several reasons. Ensure the upper and lower thread tensions are as weak as possible. Also, make the thread take-up spring tensions as weak as possible, and move the stopper to as high a position as possible to address the thread take-up spring operating range. Adjust the presser foot pressure if it's too strong. Reduce the sewing speed using the sewing speed control keys, and adjust the thread take-up amount if it's too small.

      Loops appearing in the seam of your Brother Sewing Machine could be due to a few reasons. Ensure the thread path is smooth by polishing it with a fine grain file or sandpaper. Check that the bobbin is turning smoothly; pull out the lower thread to check for slackness, or replace the bobbin or bobbin case. Finally, adjust the thread take-up amount if it is too large.

    Why does my Brother T-8722C Sewing Machine stop while sewing?
    • S
      Sherri HillSep 1, 2025
      Your Brother Sewing Machine might stop during sewing if the fixed stitch key is turned on. Press the fixed stitch key so that the indicator turns off. Another possible reason is that the power supply voltage is too low, so check the power supply.
