Sharp MZ

Thank you. My problem is that the gears don’t seem to be driven by anything. They are just motionless. When I press the paper feed button it releases the rollers but does not move or drive them round to feed the paper through

I have an MZ - 1P01 Colour Printer Plotter that needs repair as the Paper Roller does not turn.
Is there anyone on the Forum that can assist me to find out how to repair the MZ - 1P01 ?
