Troubleshooting
A-18
Character or
decorative patterns
are misaligned.
Pattern adjustment settings were set incorrectly. Revise the pattern adjustment settings. D-5
Pattern does not
turn out.
Wrong presser foot was used. Attach the correct presser foot. B-34
Did not use a stabilizer material on thin fabrics
or stretch fabrics.
Attach a stabilizer material. D-4
Thread tension is set incorrectly. Adjust the thread tension. B-41
Fabric was pulled, pushed or fed at an angle
while it was being sewn.
Sew while guiding the fabric with your hands so
that the fabric is fed in a straight line.
B-35
The thread is tangled, for example, in the
bobbin case.
Remove the tangle thread. If the thread is
tangled in the bobbin case, clean the race.
A-2
Embroidery pattern
does not sew out
correctly.
Thread is twisted. Use scissors, etc., to cut the twisted thread and
remove it from the bobbin case, etc.
A-8
Thread tension is set incorrectly. Adjust the thread tension. B-41
Fabric was not inserted into the frame correctly
(fabric was loose, etc.).
If the fabric is not taut in the frame, the pattern
may turn out poorly or there may be shrinkage
of the pattern. Set the fabric into the frame
correctly.
B-58
Stabilizing material was not attached. Always use stabilizing material, especially with
stretch fabrics, lightweight fabrics, fabrics with
a coarse weave, or fabrics that often cause
pattern shrinkage. See your authorized Brother
dealer for the proper stabilizer.
B-57
There was an object placed near the machine,
and the carriage or embroidery frame hit the
object during sewing.
If the frame bumps something during sewing,
the pattern will turn out poorly. Do not place
anything in the area where the frame may bump
it during sewing.
B-56
Fabric outside the frame edges interferes with
the sewing arm, so the embroidery unit cannot
move.
Reinsert the fabric in the embroidery frame so
that the excess fabric is away from the sewing
arm, and rotate the pattern 180 degrees.
B-58
Fabric is too heavy, so the embroidery unit
cannot move freely.
Place a large thick book or similar object under
the arm head to lightly lift the heavy side and
keep it level.
Fabric is hanging off the table. If the fabric is hanging off the table during
embroidery, the embroidery unit will not move
freely. Place the fabric so that it does not hang
off the table or hold the fabric to keep it from
dragging.
B-56
Fabric is snagged or caught on something. Stop the machine and place the fabric so that it
does not get caught or snagged.
Embroidery frame was removed during sewing
(for example, to reset the bobbin). The presser
foot was bumped or moved while removing or
attaching the embroidery frame, or the
embroidery unit was moved.
If the presser foot is bumped or the embroidery
unit is moved during sewing, the pattern will not
turn out. Be careful when removing or
reattaching the embroidery frame during
sewing.
B-61
Stabilizer is incorrectly attached, for example, it
is smaller than the embroidery frame.
Attach the stabilizer correctly. B-57
Loops appear on
the surface of the
fabric when
embroidering.
The thread tension is incorrectly set. Adjust the thread tension. E-26
The combination of the bobbin case and bobbin
thread is incorrect.
Change the bobbin case or bobbin thread so
that the correct combination is used.
