There is no area that is moving in this reader. No wear and no tear for the most of the part, so maintenance is minimum . It is recommended for you to wipe the surface of the platen ( silver plate where you place your hand ) with soft clothe to get rid of the dirt in the platen. If you use battery backup kit, you might wish to change it every other year or so.
