Embroidery pattern
does not sew out
correctly
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.
E-21
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.
E-26
Stabilizer is incorrectly attached, for example, it
is smaller than the embroidery frame.
Attach the stabilizer correctly. E-11
Loops appear on the
surface of the fabric
when embroidering
The thread tension is incorrectly set. Adjust the thread tension. E-30 to E-32
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. E-22
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.
E-21
Embroidery unit does
not operate
There is no pattern selected. Select a pattern. E-3, E-58
Main power switch is not turned on. Turn the main power to ON. B-21
Embroidery unit is not attached correctly. Reattach the embroidery unit correctly. B-64
Embroidery frame was attached before the unit
was initialized.
Perform the initialization process correctly. B-64
Pointer of embroidery
foot “W+” with LED
pointer does not
indicate the position
correctly
With thick elastic fabric, the position will be
misaligned only at raised parts in the fabric.
Manually adjust the position according to the
thickness of the fabric.
B-63
With fabric having a very uneven surface, the
position is not correctly aligned.
The pointer indication should be used only as
a reference.
B-62
Specifying with
sensor pen cannot be
done accurately
The sensor pen has not been calibrated. Before using the sensor pen for the first time,
be sure to calibrate it.
B-74
The pen is being held differently than when it
was calibrated.
When using the sensor pen, be sure to hold it
at the same angle as when it was calibrated.
The specification location may be misaligned
if the pen is held at a slightly different angle.
In this case, make fine adjustments after
making the selection.

CAUTION
• This machine is equipped with a thread detection device. If the “Start/Stop” button is pushed before the
upper threading is done, the machine will not operate properly. Also, depending on the pattern selected,
the machine may feed the fabric even if the needle is raised. This is due to the needle bar release
mechanism. At these times, the machine will make a sound different from what is made during normal
sewing. This is not the sign of a malfunction.
• If the power is disconnected during sewing:
Turn the main power to OFF and unplug the machine.
If you restart the machine, follow the instructions for operating the machine correctly.
