Question about Janome Memory Craft 9000 Computerized Sewing Machine

1 Answer

The upper tension will not tighten on my Janome MC 8000. I have had it since '93 with no problems and all of a sudden when I was stitching the tension became loose on top (it was looping and making a mess underneath). I have tried adjusting the screw to the left (inside the machine) of the take up lever to no avail. Nothing seems to make a difference. Is there any hope for this machine. It's my very favorite!

Check for lint or thread in the top tension unit.....try "flossing" (as you would teeth) with a clean cloth.
Symptoms indicate top tension is being kept slightly open by debris.
Playing with the screw inside the cover on left of tension unit is not a great idea, it is designed for fine adjustment when tensioner is clean, so try to reset back to what it was before fiddling if you can remember how may turns you made.
If you continue to have problems, send a quick email (please mention the model and issue, we get a LOT of requests) and I shall see what else we can do to get you back on track.

I have a Janome Horison Memory Craft 8900 SpEd, thread looping on backing side for free motion. DO i NEED Part No. 200-445-007 Janome Bobbin Holder for Free Quilting and Hand-Look Quilt Stitch.


Free motion quilting is a finicky function, much more than most other sewing. Since you are getting loops on the back of the fabric, try increasing the upper thread tension. Tension causes the top and bobbin threads to pull against each other. If the pull is not equal, the threads will be pulled to one side or the other.

If you continue to experience looping under the fabric, it could be that the top thread is not fully seated in the tension disk. Try this:

Remove the top thread completely from the machine.
Be sure to install a brand new sharp needle.
ALWAYS RAISE the presser foot and rethread from the beginning.
Retest your machine.

However, if you don't find a fix, $25 for the special bobbin holder is probably a reasonable cost if it takes care of the problem. The reviews seem to be good:

How do I adjust tension on a Janome Harmony 9102D


Sounds like you want to do a rolled hem for a handkerchief edge, I do the following to create a rolled hem on my over locker. Take out left needle and cut and remove that thread. Open front cover and slide back lever for the stitch finger in the needle plate, this finger stops the fabric rolling under thread tension normally so you need to pull it back out of engagement. Your Janome may have a similar means to select the rolled hem or you may need to remove the stitch finger with a screwdriver, it varies between models.

Thread upper looper with wooly nylon and right needle and lower looper in matching colour thread. (You can go wooly on the bottom looper but it hardly shows so I never bother.) Disengage upper blade and move the fixed lower blade to the right to trim less, then lower upper blade back into position. Now tension, needle leave alone (5)' upper looper very loose (2-3) and lower looper tighten up to 6-7 and test stitch. You want the upper looper thread to go right underneath and the lower looper thread to disappear against the needle stitch. And the fabric to roll inside the stitching. Finesse tensions on the loopers until this is right, you may need to change blade position too, depends on weight of the fabric and how it rolls. Once this is right turn stitch length down to close up stitching, 0.8 or even 0.5 if you want full coverage. Thats it. You can use differential feed if you want a fluted rolled edge, nice on knits.

Advice on how do I adjust tension


I don't have a Janome, but in general
if your seam has extra loops at the top
looks like ^-^-^-^
loosen the upper tension a bit and tighten the bobbin tension a bit.

If the extra loops are at the bottom
sort of like \/-\/-\/-
do the opposite - tighten the upper tension a bit and loosen the bobbin tension a bit.

The upper tension is easy; it's usually a dial with +/- numbers. The bobbin may be more difficult. For mine, it's a screw on the side of the bobbin case. A web search seems to indicate Janome is the same.

Practice on scraps of the same weight and use the same thread you're using on your project until you get the tension right.

good luck

My Memory Craft 3500 suddenly seems to have no tension in the upper thread. Stitching looks fine on the top, but there are big thread loops on the bottom. Changing the upper tension dial doesn't seem to...


Hello,

It could be a wad of lint in the upper tensioner disks keeping the disks apart. I have also seen on older machines where the thread has actually cut a groove into the disks. If you can dis-assemble the tensioner, clean and inspect. Be very careful to memorize the part order in which you remove the parts, this will help when re-assembling it.

Good Luck,

Lower stitch tension


Just a few tips, which might help. Try these on cotton material first. Make sure you use the same quality thread for both, upper and lower stitching. I find Gutterman the best. Secondly, turn the bobin the other way round. Thirdly, make sure there is no fluff under the needle.Remove the plate and use a little brush. Fourthly, test the bobbin tension by holding it by the thread: if it falls to the ground, it is too loose, if it stops suddenly in the air, it is too tight. When it drops a little and then stays, that it the correct tension. I hope this helps.
