Symptom, Cause/solution
Reference
Fabric was not inserted into the frame correctly
(fabric was loose, etc.).
Stabilizing material was not attached.
28
• Always use stabilizing material, especially with
stretch fabrics, lightweight fabrics, fabrics with a
30, 55,
coarse weave, or fabrics that often cause
62
pattern shrinkage. See your authorized Brother
dealer for the proper stabilizer.
30
There was an object placed near the machine, and
30
the carriage or embroidery frame hit the object
during embroidering.
30
Fabric outside the frame edges interferes with the
arm, so the embroidery unit cannot move.
106
• Reinsert the fabric in the embroidery frame so
that the excess fabric is away from the arm, and
rotate the pattern 180 degrees.
30
Fabric is too heavy, so the embroidery unit cannot
move freely.
26
• Place a large thick book or similar object under
the arm head to lightly lift the heavy side and
28
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
30
off the table or hold the fabric to keep it from
dragging.
106
Fabric is snagged or caught on something.
28
• Stop the machine and place the fabric so that it
does not get caught or snagged.
23
Embroidery frame was removed during
embroidering (for example, to reset the bobbin).
The presser foot was bumped or moved while
106
removing or attaching the embroidery frame, or the
embroidery unit was moved.
Stabilizer is incorrectly attached, for example, it is
smaller than the embroidery frame.
30
Loops appear on the surface of the fabric when
embroidering
30
The thread tension is incorrectly set.
The tension of the upper thread is incorrectly set
for the combination of the fabric, thread and
pattern being used.
• Use the embroidery needle plate cover.
106
The combination of the bobbin case and bobbin
thread is incorrect.
