Post a sample of the defect. Odds are the laser/scanner optics are dirty. Easy to clean. Just remove the top cover and the black box in the center is the laser/scanner. Remove cables and 4 screws and turn over and clean the glass mirror you see in the opening. Odds are lots of dust build up on the one side. Use a dry q tip. Just pay close attention to the shutter mech to put it back right.
