After finding disjointed information all over the net about a problem with my sewing machine (abovementioned), I decided to put some clearer instructions right here…right now!
So, here’s the problem.
You’ve just wound a bobbin on your Janome MemoryCraft 4900QC. You click the spindle back to normal sewing mode when HELLO, the bobbin icon stays on the screen!
Oh no, you can’t do anything with your machine!
These new electronic fan-dangled things! Why on earth don’t you just own a treadle sewing machine and just be done with computerisation!
What do you do?
Well, instead of cursing your machine and vowing to never again touch a sewing machine with it’s own brain, think about fixing it yourself (before taking it back to the serviceman, that is).
You may find it’s your bobbin winder sensor not engaging.
To check if this is the problem, go straight to step ‘3’ below.
Follow these COMPLETE instructions if you find that your bobbin winder sensor needs adjusting:
- Turn off the machine.
- Remove the top cover.
This step requires photos:
- Enter ‘Adjusting mode’: Turn on the machine and at the same time push down the needle up/down button and the stay-stitch button.
Press ‘5’ when menu comes up.
You are now in ‘Adjusting Mode’.
We need to focus on SP (bobbin spindle position). Click over the bobbin winder to see if it’s values change to either ‘OFF’ or ‘ON’. If not, then we definitely need to adjust the sensor.
NOTE: The SP should show ‘ON’ when bobbin winder spindle is set to the bobbin winding position. And/or ‘OFF’ when bobbin winder spindle is returned to sewing.
- Loosen setscrews to adjust position of the switch fixing plate.
- Once everything’s going the way you want it, tight set screws and replace cover.
And there you have it, you’re ready to go again 🙂
