Question about Janome Sewing Machines

1 Answer

My Janome 6500p is having bobbin issues

The last three times I have sewn, my Janome gets repeated jams. The jam only happens when i sew fast. If I sew slow, the jams do not occur, but i am aware of an unnatural rocking of the bobbin case while I am sewing. With the first three jams, the bobbin case passed the red line- up dots which resulted in a burr. The burr has been filed. The needle has been replaced, the bobbin housing has been cleaned via air in a can, and I am at a loss. There are no local dealers or techs within 100 miles of me...hope I can fix it myself once I identify the problem--Any thoughts?

Here are my suggestions
1. when your sewing check to see if the thread is coming off the thead take up lever,, I've had this to happen to me & it can jam a sewing machine up
2. it's possible that the bobbin case is worn & needs to be replaced
3.also check your top tension
4. try rethreading the machine top thread & bobbin

If you take the needleplate off and remove the bobbin case, check yourself whether there is damsge to the bobbin case by visual inspection and lightly rub finger over top and side edge where the thread will pass as it is drawn to make the stitch...............all should all be smooth or trouble ensues.
If there are obvious needle strikes, a short term solution may be to very gently file the burr, but use very fine emery paper very carefully or you may make things worse.
If you are using a waxy or silicon based thread, these deposit a residue inside the bobbin case and tension disks, so use methylated, de-natured spirit on a clean cloth to remove.
Also check the tension disk are clean and clear of lint, as this is the number one issue with looping threads......... try this tutorial for more detail:


Please TRY the solution BEFORE giving your considered rating.


Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.
The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle, 
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your 
projects). 

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with 
a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to 
disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension. 

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean 
the hook race area (where bobbin case sits) 

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned. 

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all 
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at 
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is, 
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine 
case....no case ? then make some sort of cover ! 

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with 
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the 
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

While quilting I heard the machine hammer--I stopped it and changed out the bobbin to only only have the thread not pick up from the bobbin. Now I can not sew the the machine.


Remove and replace the needle (it is probably damaged now)
Test stitch a seam. If you still have problems
Check the timing of your machine.

Janome mini heavy duty sewing machine


when you sew keep a eye on the thread take up lever & see if the thread comes off while your sewing, I've had this happen to me & I've been sewing for over 30 years. if this does happen, take a pair of pliers & very gently close the take up lever just alittle but not enough to damage it.
also check the needle to see if it's damaged--if your not sure change the needle--flat side goes to the back of the machine
always make sure the fabric & needle & thread are compatable--the thread must be able to pull thru the needle with out any problem
also check to make sure there are not any burrs on the needle plate or bobbin or bobbin case

Janome memory craft 6500 sewing machine...all of a sudden, the bobbin thread does not attach itself to the needle thread...i have taken off the plate, cleaned out the dust, rethreaded both top and bottom...


Has the bobbin case dislodged and moved? there should be two red marks one on the bobbin case and one on the outer holder, are they lining up? Sometimes as these cases are held by a magnet, they will get dislodged and move slightly, especially in a jam up.
Take out the bobbin case and clean under it, then replace it matching up the red marks.

10_17_2011_5_44_09_am.jpg

If the bobbin case has actaully been struck by the needle during a dislodgement, it may well pierce the bobbin case plastic, look for burring or marks on the outer flange area. If this has occured, the thread may catch on the burr as it comes over the bobbin and jam again.

You can buy a new bobbin case if yours is damaged or maybe just file the burring with an emery board (remove it from the machine first of course).

Lastly, check your needle hasn't been bent, burred, or put in backwards, any of these can prevent a stitch from forming.

If all the above fails, then it is possible that the timing has been knocked out and you will need to get it serviced by a technician.

Janome 6500 jamming - cleaned out bobbin case - no help


Have you removed the bobbin holder and then put it back in lining up the little red markings on the right hand side? If the case has moved slightly then it will keep jamming and the bobbin thread won't clear to form a stitch. The case is held in place by a magnet and a stopper but it will dislodge if you have a bad thread jam, then it keeps happening even if you have removed all the thread because its not in position.

Check this solution for image how to remove and replace the bobbin case. http://www.fixya.com/support/t9289728-bobbin_seems

When you take out the bobbin case, carefully inspect it for any damage and burrs in the black plastic, if there are any then file them carefully out with a nail file or fine sandpaper, a burr will keep catching thread too. Or you may actually need to replace the bobbin holder if it has been pierced by the needle badly, they are about $35 or so.

You may also want to get it serviced. On my 6500 during its last service the technician added a little piece that is a Janome "after sale replacement" part. It is slightly longer than the standard part, and is a little metal bit on the left hand side of the rotary hook area which is holding the bobbin holder in place better. Haven't had a major jam up since this was fitted so you may want to get this fitted on yours too.

You need to ask Janome these questions, rather than Fixya I think. The plastic bobbin in the plastic bobbin holder does make a little bit of noise but I don't find it problematic.

Providing you are using "Janome" plastic bobbins and are putting them in rotating the right way, as per the little image on the clear cover, there is no reason that the thread cutter should be dislodging the bobbin. When I use the thread cutter, my bobbin turns as thread is drawn off it, but it doesn't move upwards.

Sounds like you have already replaced the black plastic bobbin holder, is that what you mean by "Shuttle"??

My 6500 has had 2 replacement bobbin holders as I keep striking it with the needle during jam ups, which caused plastic burrs on it. On the last service the technician added a little piece that is a janome "after sale replacement" part. It is slightly longer than the standard part, and is a little metal bit on the left hand side of the rotary hook area which seems to be working at holding the bobbin holder in place better. Haven't had a big jam up since he fitted it. But before this, I would dislodge the bobbin holder with a small jam, and then it would just jam and jam until I removed the needle plate with the screwdriver, removed the bobbin and bobbin holder, cleaned out all the thread fragments, then replaced the bobbin holder back into the correct position lining up the two red arrows. Then replaced the needle plate and rethreaded. I learnt to modify my sewing expectations and not try to sew really thick seams as this will just dislodge the bobbin holder again. Jeans hems were always my problem seam, I use a "Seam Jumper" now to handle going from thin to thick seam, and so far, so good.

So I would suggest you ring Janome in Akld and talk to their technical advisor a bit, describing your problem. They may suggest sending it to them for a check out to establish what is going wrong.

If you have trouble describing the issue to then you could always film it with a digital camera and send the file to them.

My only other thought is how you wind the bobbins. It is really important to wind the bobbin smoothly and evenly top and bottom, my 6500 will wind all in the middle if I let it just run, so I always wind carefully and give the thread a nudge with my fingertip to ensure it fills evening top, middle and bottom. But it sounds like you are an experienced sewer and know this already.

I'd say ring Janome and have a chat, I find if you keep your approach friendly and neutral rather than "I've never got on with this machine" that you may get some help from them at resolving this issue.

I have a Janome 4900Qc which has the sign Stop for Safety Purposes, this comes up really often, it has been back and been checked but no better now


Are you having thread jamming problems before you get this message?

I found that my bobbin holder which is held by magnets was being dislodged when I had a thread jam up, usually when I was trying to sew something very thick over a seam such as jeans hems.

Have you mastered removing the needle plate and the bobbin holder to clean in under it and putting this all back together again? With my 6500P, the needle had been striking the bobbin holder when it dislodged and rotated out of postion, the bobbin case had holes and damage to the plastic which was then catching the thread as the bobbin rotated making the jams happen.

Each time, I would dismantle the bobbin holder, clean everything, cut the jammed up threads, check the bobbin case and give the damaged bit a file with a nail file to make it smooth again, then put it back matching the red markings on the bobbin holder and the stopper, rethread and start over. I have bought two new bobbin cases too and taken it back to the dealer a couple of times over 5 years.

I've now learnt to not try to stitch over the thick seam intersections, I'll stop before, lift the pressure foot, move the work past the seam, then restart sewing. However, my machine was just serviced last week and it looks to me like the mechanic has added a part to hold the bobbin case in better, its like a little black lug on the left screwed into the outer housing. So perhaps Janome have addressed this issue with an aftermarket repair.

Apologies if this is telling stuff you already knew, good luck.

Thread gets caught on bobbin and jams


You may need a new bobbin case if your machine is an older model.. Over time the cases get nicks in them causing thread to catch on it. Have you lubricated the bobbin area? Needs one drop of oil for every ,I believe it is 25 hours of usage. That may take care of it. The oil goes under the bobbin right in the center of bobbin case. Remove your bobbin before applying the oil. i hope this helps you. Good Luck
