The light tunnel is out of adjustment or is collasped.. you can take the cover off (with the machine unplugged) there are 2 screws on the engine,1 you can see thru the hole in the top off the main board, the other is down next to the power supply. that is the one you need to adjust. you will need a small allen wrench that will fitin the screw and still be able to turn it without hitting the power supply. turn the screw towards the direction of the banding. try 3 small turns and put back together and see if its better or worse. if better adjust some more, if worse the tunnel has collasped.
