We have three Janome MB4 embroidery machines in the office and they are frequently jamming, resulting in the .
We are based in Northern Mozambique and our nearest technician is in Johannesburg and it is expensive to bring him up to fix the machines (>$1600). I want to learn how to do this myself.
At the moment I have the needle alignment out on all machines. I have a service manual which shows me how to remove and replace parts - which is potentially very helpful. So, if I know the sequence of maintenance activities I need to do to resolve this issue, then I might be able to fix the machines myself using the service manual.
Can anyone help by indicating what are the steps I need to take to resolve this problem? I have looked for a Janome video dealing with this specific issue, but to date I have not found one which addresses this problem.
Thank you very much for your assistance.
