Several solutions for minor problems are described below. If the problem persists, contact your dealer or nearest
authorized Brother dealer.
■ The thread was accidentally cut
automatically and the bobbin thread
is caught inside the machine
Cut the thread near the fabric above the
needle plate, and then remove the fabric.
• If an embroidery pattern was sewn, remove
the embroidery frame.
Remove the bobbin, and then hold it out
toward the left side of the machine.
Lower the presser foot.
Apply slight tension on bobbin thread by
holding thread out to the left side of presser
foot. Press the "Thread Cutter" button
• Do not pull on the thread with excessive force,
otherwise the machine may be damaged.
■ Correcting bobbin work tension
If the top thread shows on the bobbin side of the
fabric, increase the upper tension (Refer to
"ADJUSTING THE THREAD TENSION" on
If the top thread still shows on the bobbin side of the
fabric, reduce the tension of the bobbin thread or
bypass the bobbin tension. (Refer to "ADJUSTING
THE THREAD TENSION" on page A-16.)
Some bobbin threads are too coarse to pass through
to wrong side of fabric. In this case, be sure to color
match top thread with bobbin threads.
Example: Decorative Stitch
a Correct tension
b The upper thread tension is too loose, or the
bobbin thread tension is too tight.
■ The bobbin thread catches on the
tension spring of the bobbin case
Sew with no tension applied to the bobbin thread.
(Refer to "When tension is not applied to the bobbin
thread" on page A-7.)
