TROUBLESHOOTING
If the machine stops operating correctly, check the following possible problems before requesting service.
You can solve most problems by yourself. If you need additional help, the Brother Solutions Center offers the
latest FAQs and troubleshooting tips. Visit us at [http://solutions.brother.com].
If the problem persists, contact your dealer or the nearest authorized service center.
Frequent troubleshooting topics
Detailed causes and remedies for common troubleshooting topics are described below. Be sure to refer to this
before contacting us.
Upper thread tightened up
■
Symptom
• The upper thread appears as a single
continuous line.
• The lower thread is visible from the upper
side of the fabric. (Refer to the illustration
below.)
• The upper thread has tightened up, and
comes out when pulled.
• The upper thread has tightened up, and
wrinkles appear in the fabric.
• The upper thread tension is tight, and the
results do not change even after the thread
tension is adjusted.
a
Lower side of fabric
b
Lower thread visible from upper side of fabric
c
Upper thread
d
Upper side of fabric
e
Lower thread
■
Cause
Incorrect lower threading
If the lower thread is incorrectly threaded, instead
of the appropriate tension being applied to the
lower thread, it is pulled through the fabric when
the upper thread is pulled up. For this reason, the
thread is visible from the upper side of the fabric.
■
Remedy/check details
Correctly install the lower thread.
a
Remove the bobbin from the bobbin case.
b
Place the bobbin in the bobbin case so that
the thread unwinds in the correct direction.
• Hold the bobbin with your right hand with
the thread unwinding to the left, and hold
the end of the thread with your left hand.
Then, with your right hand, place the bobbin
in the bobbin case.
If the bobbin is inserted with the thread
unwinding in the wrong direction, sewing will be
done with an incorrect thread tension.
