  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.

Why are loops appearing in the seam of my Brother T-8422C Sewing Machine?
- B
  Bryan BanksSep 2, 2025
  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 is there excessive tension (puckering) in my Brother T-8422C Sewing Machine seams?
- C
  Carrie MendezSep 1, 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.

Why is the lower thread tangled on my Brother Sewing Machine?
- J
  James MillerAug 29, 2025
  If the lower thread is tangled at the sewing start, spinning of bobbin during thread trimming on your Brother Sewing Machine, make sure the bobbin spins in the opposite direction to the rotary hook when the lower thread is pulled. Ensure the bobbin winding amount is not more than 80%. Attach the anti-spin spring if your model has a thread trimmer. If the bobbin is not turning smoothly, replace it. Only use bobbins specified by Brother.

How to fix upper and lower thread tension on a Brother T-8422C?
- E
  Eric MooreAug 27, 2025
  If the upper or lower thread is not tight on your Brother Sewing Machine, ensure the thread is correctly threaded. Adjust the upper or lower thread tension if it is too weak. If the thread take-up spring operating range is too small, lower the position of the stopper. If you are using a sewing machine with medium-weight material specifications, poor thread tightening may occur depending on the type of material being sewn. In such cases, replace the presser foot with one that has slots on the underside, or replace the feed dog with a grooved feed dog.

  Skipped stitches may occur on your Brother Sewing Machine because the needle tip is bent or blunt. Replace the needle if it is damaged. Make sure that the needle and the thread are correctly installed. Adjust the presser foot pressure, and if the needle is too thin, replace it with a thicker one. Also, check the height of the presser foot, the tension of the thread take-up spring and the thread take-up amount and adjust if needed.

  If the needle is bent or broken, replace it. Ensure the needle is correctly installed and the machine is properly threaded. Check the oil tank and add oil if the level is below the bottom reference line. Adjust the upper or lower thread tension if it's too weak or strong. Clean the rotary hook if it's blocked. Adjust the stopper position if the thread take-up spring operating range is too small. Smooth or replace damaged parts like the rotary hook or feed dog. Smooth damaged thread paths or replace them.
