 Switch the sewing machine to the symbol “O” position to turn it off when making any adjustments in the needle  area.
 Do not use a damaged or incorrect needle plate, as it could cause the needle to break.
 Do not push or pull the fabric when sewing, and follow careful instruction when free motion stitching so that  you do not deflect the needle and cause it to break.
7This machine is not a toy:
 Your close attention is necessary when the machine is used by or near children.

OUTSTANDING FEATURES
Display the Fabric While 
Aligning the Embroidering 
Position
The fabric hooped in the embroidery frame can be 
displayed on the LCD so that the embroidery 
position can be easily aligned.
This feature allows you to easily combine patterns 
while checking the final image.
See “Display the Fabric While Aligning the 
Embroidering Position” on page 211.
Change the Pattern Size While 
Maintaining the Desired Thread 
Density (Stitch Recalculator)
In the embroidery edit screen, the size of the 
pattern can be changed while the desired thread 
density is maintained.
With this function, the pattern will be enlarged or 
reduced at a larger ratio than with normal pattern 
resizing.
See “Changing the Pattern Size While Maintaining 
the Desired Thread Density (Stitch Recalculator)” 
on page 270.
Expand Your Creativity With 
Bobbin Work
Example with decorative stitches
You can create bobbin work, which gives a three-
dimensional appearance to the surface of the 
fabric, by winding the bobbin with heavy weight 
thread or ribbon too thick to be fed through the 
sewing machine needle and sewing on the wrong 
side of the fabric.
Bobbin work is sewn using the special bobbin case 
(gray) included with this machine.
See “How to Create Bobbin Work” on page 307.
Multi-Function Foot Controller 
Allows You Easy Sewing
The multi-function foot controller allows you 
various sewing machine operations in addition to 
starting/stopping sewing, such as thread cutting 
and reverse stitching, can be specified to be 
performed. See Operation Manual Addendum. 
						

							7
Find New Color Schemes With 
the Color Shuffling Function
With the color shuffling function, the machine 
suggests new color schemes for the embroidery 
pattern that you have selected. After you select the 
desired effect from one of the four available color 
schemes (“RANDOM”, “VIVID”, “GRADIENT” 
and “SOFT”) the sample for the selected effect is 
displayed.
See “Find New Color Schemes With the Color 
Shuffling Function” on page 283.
LED Pointer Shows You the 
Needle Drop Position
Included Embroidery foot with LED pointer 
indicates the needle position with a red LED point.
The LED pointer shows you the location of the 
needle penetration so that it is easier to adjust the 
embroidery position.
See “Attaching Embroidery Foot “W2”” on 
page 186 of this guide, and Operation Manual 
Addendum.
Create Patterns With My Custom 
Design
Any image that you draw in the LCD screen area 
of your machine can immediately become an 
embroidery pattern. Specify colors and sewing 
settings as you desire.
Compose embroidery from children’s drawings or 
of your signature to add to your original artwork. 
This is a function that everyone will enjoy using.
The included pen tablet makes this function even 
easier to use.
Refer to the instruction manual (PDF format) stored 
in the My Custom Design CD.
Easily Perform My Custom 
Design Operations With the 
Included Pen Tablet
The included pen tablet can be used to perform 
My Custom Design operations effectively, along 
with normal screen operations. Since the range of 
operation with the pen tablet is wider than the 
machine’s LCD screen, you can easily perform 
intricate procedures.
See “Using the Pen Tablet” on page 23 and “Using 
the Pen Tablet” on page 34.
