Why is there puckering when sewing with my Brother S-7220D-405?

If the upper thread tension is too strong, make it as weak as possible. If the lower thread tension is too strong, make it as weak as possible. Replace the needle if it is blunt; use as thin a needle as possible. Make the thread take-up spring tension as weak as possible, and lower its position as much as possible. Adjust the presser foot pressure. Use the sewing speed key to reduce the sewing speed gradually. Tilt the front of the feed dog down slightly.
