Symptom
Embroidery not
neatly done.
Probable Cause
The fabric is not fully stretched on
the embroidery frame. The fabric
is loose.
No stabilizer material is attached.
The thread is tangled and the
bobbin case, etc., is plugged up.
The thread tension is incorrect.
Objects are placed near the
carriage or embroidery frame.
Material coming out of the
embroidery frame is causing
problems.
When embroidering on a heavy
fabric, the fabric is hanging off the
table.
The fabric is catching. It is
pinched.
The carriage was moved while the
embroidery frame was being
removed or attached during
embroidery.
Remedy
Stretch the fabric properly on the
embroidery frame.
Always use stabilizer material for
embroidery with stretch fabrics, thin
fabrics, fabrics with a loose weave
and fabrics where stitches easily
contract.
Remove the tangled thread. When
the bobbin case is plugged up, clean
the race.
Adjust the tension of the upper
thread.
If the embroidery unit carriage or
embroidery frame bumps into objects,
the pattern will be misaligned. Do not
place objects within the range of
embroidery frame motion.
Stretch the fabric on the frame once
again so that the material coming out
of the embroidery frame does not
cause problems, rotate the pattern
and embroider.
If embroidery is done with the fabric
hanging off the table, the embroidery
unit movement will be impaired.
Support the fabric while embroidering.
Stop the machine and set up the
fabric correctly.
If the carriage is moved during the
process, the pattern may be misaligned.
Be careful when removing or
attaching the embroidery frame.
