Probable Cause Remedy
Check that the bobbin is wound so that
it is about 80% full and that the thread
is evenly wound. If the bobbin is not
correctly wound, replace the bobbin
with one that is correctly wound or
rewind the bobbin.
Consult your nearest authorized
Brother dealer.
Replace the needle.
Firmly set the fabric in the embroidery
frame so that it is taut.
The thread quality is too weak due to
age of thread. Replace thread.
Using a data design system, correct the
thread density and overstitching
settings in the embroidery data.
Correctly thread the bobbin thread.
Replace the bobbin.
Remove the thread jammed and clean
the hook.
Use the correct bobbin.
Replace the bobbin case.
Thread the upper thread correctly.
Replace the needle with a new one.
Correctly install the needle.
Clean the hook and the needle plate.
Consult your nearest authorized
Brother dealer.
Improper twisting results in irregular
loop formation. Try using a new spool.
Use tweezers to remove any tangled
thread from the hook.
If the fabric is not taut, the pattern may
become misaligned or the stitching
may shrink. Be sure to correctly frame
the fabric in the embroidery frame.
Use stabilizer (backing) when
embroidering on thin or stretch fabrics,
fabrics with a coarse weave or fabrics
that easily allow the stitching to shrink.
<When using the optional cap frame>
Use heavyweight stabilizer when
embroidering on a cap made of soft
material.
The pattern may become misaligned if
the carriage or embroidery frame is
hitting objects. Make sure that there are
no objects within the operating field of
the embroidery frame.
Stop the machine, and then correctly
position the fabric.
