Fabric was not inserted into the frame correctly
(fabric was loose, etc.).
If the fabric is not stretched tight in the frame,
the pattern may turn out poorly or there may
be shrinkage of the pattern. Set the fabric into
the frame correctly.
203
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
dealer for the proper stabilizer.

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.

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.

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.

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.
