Question about Janome Memory Craft 4900QC Mechanical Sewing Machine

2 Answers

My winding bobbin display will not go off screen. I wound a bobbin and when I moved the switch back to remove the bobbin, the display will not leave the screen. It will not go away even when I turn the machine off and on again. How do I fix this problem? The machine is a 4900QC Thanks & regards Julie Parr

The machine has a small micro switch under the lid of the machine that is either stuck or bent. Remove the top and look in the area of the bobbin winder and flip the winder to engage and disengage. You should see a swith that the bobbin winder pushes against. That should be the problem, if it is bent you may be able to straighten it out.

    Thank you for this advice. This seems to be the problem because when I move the micro switch the machine 'pips' and it goes into sewing mode. But I cannot remove the top to get into the machine to see the switch clearly. Any more advice please?
    Thanks

    There are 2 screws which hold down the top cover, one is to the left end of the machine, kinda hidden betewwn the top and the end cover, the other is near the bobbin winder at about the 11 oclock position, they must be removed. *caution* There is a screw near the bobbin winder at a bout 1-2 oclock that is smaller, do not loosen it.

    Good luck!

    This solution led to me being able to fix mine also. I had the same problem and opened the machine as per the guidance(with my MC4900QC I also had to take off the cover on the left hand side of the machine to get the top section off. I pushed the bobbin winder across, the switch didn't seem to be bent but I did notice that there was a little screw that was linked to the parts of the bobbin winder that was loose. I tightened this screw and bingo! Thanks for helping me along the way Douglas!

Thanks for this help Douglas as it led me to fixing my machine with the same error but slightly different solution. I had to undo not only the 2 screws mentioned but also the left hand side portion of the machine in order to remove the top. I checked the switch and it didn't seem bent but I did notice that the screw which held down the bobbin winder component was loose. I tightened it and bingo! Brilliant! Thanks again for your guidance sending me in the right direction.

Bobbin is not feeding properly- didn't wind on evenly.


It is important that the bobbin be wound smoothly for the machine to operate properly. First, check that you are threading the machine correctly to wind the bobbin. There is a tensioner for the bobbin winder that helps wind the bobbin smoothly so incorrect threading will cause issues. Also, try to wind your bobbin slower. There is no advantage to winding the bobbin on high speed.

If you continue to have bobbin winding issues, there is a standalone bobbin winder (SideWinder) avlb at JoAnn's or even Amazon for ~$30,. They are electric or battery operated. Be sure to verify your machine bobbins will work on the SideWinder before purchasing as some bobbins are not compatible. The bobbin winder is a handy gadget since multiple bobbins can be wound quickly, plus bobbins can be wound without having to unthread the machine, not to mention reducing the wear and tear on your sewing machine.

Bobbin winder is engaged and shows up on screen correctly, but sewing mode is still engaged and bobbin winding keeps stopping.


check the drive knob on the end of the machine
it should be loose when winding a bobbin
if it is tight or seized then that will drive the needle

Code 88 starts flashing as well as all the stitching lights on the panel when I try to thread the bobbin. I can sew, that is NOT the problem, threading the bobbin is. What is Code 88? I am not interested...


Turn your machine off and leave it off. Remove all bobbins - in the machine & from the pin. Remove all thread - from threaded machine and bobbin thread path. Clip the machine thread at the spool and pull the needle thread towards yourself. Clip bobbin thread at spool and close to bobbin, then pull towards you through thread guides. This keeps the tension where it belongs. Move the bobbin winding shaft from normal sewing back to winding bobbin a couple times. It should click in place when moved to the winding position. Check to see if there is any thread that has slipped under the bottom of the bobbin and wound itself around & under the bottom of the shaft. Carefully unwind to clear. If the shaft does not easily move back to the sewing position it is probably stuck in the winding position. Don't force it, but try to get it out of the winding position. Leave it to the left in the normal sewing position (unclicked). Check to see if there is any thread caught anywhere along the path from spool to the winding pin. Pay close attention to the first thread guide and the two discs the thread slips between that control tension. Hand wind the wheel on the right towards you to raise and lower the needle a couple of times. Stop with needle in highest position. Do NOT wind hand wheel backwards (away from you). Make sure the bobbin pin is not in the winding position. Now turn on your machine. Needle should jump to default position. Move the stitch length and stitch width guides to the far right, then far left, to attain the green lights. Press the reverse stitch button to raise lower and raise the needle. It will stop in the highest position. If you still have the error code - make sure the bobbin winding pin is NOT in the winding position. Remove the needle. Lower the presser foot and run the machine without any thread a bit. If the needle bar does not go up and down most likely the bobbin pin is stuck in the winding position. If the code has cleared use your manual to carefully wind a new bobbin. Make sure you are using a 15J bobbin which this machine requires. It will not work with just any bobbin. Next, raise the presser foot then carefully thread the machine. If you don't have a manual you can download one from the Singer website. You might consider cleaning the entire machine paying special attention to the hook area and feed dogs while the power is off. If you find a lot of lint do this more frequently to prevent buildup. Take special care when replacing the bobbin care. Hope this helps. If not call Singer. It may take some time but you should be able to reach someone to help you troubleshoot. If this is an older machine I recommend taking it for repair yourself instead of sending to Singer

Just wound a new bobbin. When finished winding, I cannot get it off the winding spindle. I'm using the bobbins that came with the machine.


I'm using the bobbins that came with the machine. I moved the winding lever back to the right. It should just lift off, but it will not budge.

I just inherited another Huqvarna (this is a model 630). It was working great until I wound a bobbin on it. After I removed the filled bobbin the machine won't move the needle up and down (but the bobbin...


I do not know the Husqvarna Viking 630. However, I have used the Viking 6690 and it has a similar on-the-side bobbin winding routine. I suspect that you failed to move the bobbin winding mechanism back into the sewing position. Look closely at the area around the bobbin winding spindle. It looks like there is a lever below the spindle. Does this need to be moved or rotated? Double check the steps in the manual and check that you did the opposite steps of preparing to wind the bobbin.

On the 6690, you pull out a knob after removing the bobbin. (You push this piece in and put the bobbin onto the now exposed spindle for winding.)

I hope this helps.

Bobbin won't come off the winding spindle


Your bobbin was basically crushed slightly, to remove it simply take the thread off the bobbin and it will come off very easily.

When you wind a bobbin on a Husqvarna and you leave the machine threaded to wind the bobbin through the needle, you must take the thread down below the foot (a metal foot only) before you take the thread up to the bobbin winder. If you take the thread directly from the needle it creates too much tension on the thread and crushes the center of the bobbin so that either you can't get the bobbin off the spindle or in some cases it damages the bobbin completely.

Some threads, the kind that can stretch slightly when pulled, shouldn't be wound through the needle at all. Instead go through the first guilde and then straight down to the little metal "button like" guide and then to the bobbin. It will create much less tension on the thread and wind it much better.

Viking sewing machine 545 bobbin stuck on rewind


It should just pull off of the winder shaft. There is a small spring that sticks out from the shaft to hold the bobbin in place (at least on my wife's Viking which is a different model number than yours). Is there a release button somewhere near?

I pulled out the lubricating strip under the bobbin



Bobbin Winding 1 Put spool of thread on spool pin. ] Use spool cushion when using cross wound thread. ] Use spool cap when using parallelwound thread. 2 Lift thread guide bar all the way up, and run thread through triangular thread guide as shown in drawing. 3Run thread through bobbin winding thread guide as shown in drawing. 4 Run thread through top thread notch 1, and align bottom thread notch 2 with guide pin on bobbin winder shaft. 5 Press bobbin stop up against empty bobbin. If the bobbin stop does not slide easily between the top and bottom of the bobbin, check that the bobbin is seated properly with the guide pin (4) inserted into the lower notch 6 While holding the end of the thread, step on the foot controller for a few seconds. Once enough thread has wound itself around the bobbin to hold itself in place, release the foot controller and trim the excess thread. 7 Stop winding when bobbin Begin
8 Manually move bobbin stop back to original position. 9 Cut thread and remove bobbin.

bobbin insertion 1 Lift slide plate (and open bobbin door). 2 Put bobbin into the bobbin case. ] Run thread through thread notch and under latch spring, so that a length of about 10 cm is exposed. ] Use a bobbin case with an idling prevention spring. 3 Pull the latch lever of the bobbin case out and push the bobbin case into the shuttle race and release the latch lever. ] If the latch lever is not all the way on the hook, it may fly off during sewing and cause lower thread breakage. 4 Lower slide plate and close bobbin door, following numbers 1 2 above in order. 6 While holding the end of the thread, step on the foot controller for a few seconds. Once enough thread has wound itself around the bobbin to hold itself in place, release the foot controller and trim the excess thread. 7 Stop winding when bobbin is full. Take foot off foot controller. * Place the thread end so that it does not protrude from the bobbin. Bobbin Stop
so this will be ok and no need to worry about this

Bobbin winding message


Under the top cover, on the right hand side where the bobbin winder is, there is a small switch which is activated when the bobbin is being wound. You will need to remove the cover and reposition the switch (it's located towards the front of the machine) to make it work properly.
