The gear or timing pulley as it is called in the parts manual has a flat section on it where it sits on the shaft, through time this rounds and the paper isn't transported properly from the left hand side of the tandem tray to the right.
Hope this helps. It took me a bit of time to find this fault because if you remove the stepper motor and drive the belt and pulley by hand it moves freely and visually it looks okay. But I would definatelly check out this gear.
