Computerized sewing machines are difficult to understand if you have only dealt with mechanical machines. They rely on optical sensors, timing belts and computer logic.
This one came to me with the dreaded E1 error message. This error is particularly frustrating because the machine is telling you that the presser foot is up when it's obviously down. It locks up the entire machine and you can't do anything with it at all.
The solution requires that you take the front cover off of unit (carefully) and apply about 3 drops of oil to the pivot pin that the pressure foot position indicator level is attached to. That's all it really requires, but how many people are willing to take the cover off and deal with the electronics? This machine got it's three drops of oil and now operates perfectly.
It's kind of fascinating though to see this view of the machine, running with the front cover removed....
