Customer Question

Godd after noon.
I am using Brother Innov'is - 900. I am not new to machines. I have been using one or the other famous brands from 40 years for domestic /Personal purpose. I cleaned the bobbin cover area and removed all the lint & dust. But it has been continuously DISPLAYING "SAFETY DEVICE ACTIVATED" note. and the machine is getting jammed. It is my humble request with you to kindly help me.

The INNOVIS 900 has a safety cut-out to prevent motor damage caused by overstraining - usually a result of a thread or fabric jam.

Check in and under the hook/bobbin case, and around the top shaft at the mechanism driving the takeup lever (top thread puller...that little arm moving up/down). You will need to get inside the machine to check both regions completely.
If both regions are clear, then the machine "thinks" that there is a jam, and this would likely be caused by a faulty sensor which is not a DIY fix unfortunately, so the machine would have to go in for repair.
