Our Sharp ARC150 seems to have a static problem. It keeps misfeeding and when I open it up to get the paper out it's always at the same place where the paper is stuck to the roll of film that moves it. I've tried anti-static cleaner but it hasn't helped. How do i fix it?

In a copier static is usually a good thing. The "roll of film" you are refering to is the transfer belt...it should be static !! and not cleaned with anti-static cleaner. The belt uses the static to hold the paper in place and transport it. Putting any type of solution on the belt will probably damage it and cause further issues - especially copy quality.
It could be that the belt is not moving at the correct speed due to maybe 1)worn/broken drive gears 2)drag caused by the cleaning blade. Or there could be a sensor that is miss-reading the timing of the paper reaching a certain point and then causes a jam. Is the paper in the trays set correctly to match the paper sizes and orientation it shows on the screen? Does it give you a jam code on the display? Does it jam from all the paper trays?
