Probable Cause Remedy
Touch the key to move the desired
needle bar to be threaded into
embroidering position.
Replace and use recommended needle.
Correctly install the needle.
Consult your nearest authorized
Brother dealer.
Check the thread path, and then thread
the upper thread again.
Correctly thread the bobbin thread.
Adjust the tension of the bobbin thread.
Remove the tension dials, and then
remove any lint or dust accumulated
between the felt washers.
Set the remaining length of thread to
"Long Tail" on the second page of the
settings screen.
Correctly thread the lower thread.
Clean the tension unit. Correctly pass
the thread through the thread tension
disc. If the broken thread error occurs
after the machine is cleaned and
rethreaded, the sensor may be
damaged. Consult your nearest
authorized Brother dealer.
Remove the tension dials, and then
remove any lint or dust accumulated
between the felt washers.
Remove the tension dials, and then
remove any lint or dust accumulated
between the felt washers.
Replace the needle. Dull needles have
a difficult time passing through the
garment, causing fabrics to tear.
The simple penetration of the needle
could damage delicate fabrics. Use
stabilizer on top of fabric.
Adjust the tension according to the type
of fabric and thread being used.
Polyester thread will stretch during
sewing especially if the tensions are set
too high. After the stitching is complete,
the thread returns to its original
strength, causing puckers in the fabric.
Tightly frame non-stretchable, woven
fabrics. Loose framing will cause the
fabric to bunch up under the stitching.
Tautly frame soft knits using a stable
backing. Overstretching the garment
will cause it to look puckered when the
frame is removed.
Re-digitize the design with fill stitching
or with multiple rows of column
stitching.
