Troubleshooting
Uneven Quilt Design Corrective Measure(s)
Take-up rollers may be bowed
or bent
• Make certain the fabric is not rolled too tight, causing the poles to bow.
Check that poles are inserted completely together with the push pins
engaged so bowing won’t occur.
Leaders are stretched or worn • If fabric is beginning to stretch or fray, contact Janome to purchase
replacement leaders. Do not wash the leaders.
Thread Breaks Corrective Measure(s)
Thread is poor quality or
may have severe twisting or
thread rot
• Look for severe twisting of threads when approximately 12 to 15 inches
has been pulled off, with the ends pinched together. Cotton threads are
particularly susceptible to dry rot or wet rot which makes thread brittle.
Do not use poor quality thread, or thread that is rotted or brittle.
Top and bobbin tensions
not balanced
• Balance the tension of the needle thread after ensuring the bobbin
tension is adjusted correctly. (For more information about adjusting
tension, see Bobbin and Bobbin Tension and Top Thread Tension in the
Using Your Machine section of this manual.)
The machine head has been
threaded incorrectly or thread
spools are not positioned correctly
• Check that the machine is threaded correctly.
• Inspect for accidental double wrapping of thread on thread guides.
• Inspect the thread mast, making sure the eyelets of the mast are
directly over the spools.
• Inspect the vertical positioning of the thread cones. Tipped cones can
dramatically affect thread tension and can cause breakage.
Debris in tension discs
• Inspect for particles and remove any fuzz or debris.
Bobbin rotation is not smooth • Change the bobbin. The slightest hesitation of the bobbin rotation can
be the cause of dramatic tension change and
thread breakage.
Needle is burred, bent or dull, or
installed incorrectly
• Change the needle at least once per quilt. Make sure the needle is
installed to the top of the stop hole in the needle bar.
Needle not suitable for thread • Replace the needle to one better suited for the thread. Use the proper
size needle.
Hesitating too long at one point in
quilting motif
• Move more quickly so stitches don’t overlap or build up. When starting
the machine, begin moving immediately. Sewing in one place too long
will cause the thread to break.
