Alignment of gears in MV600 mechanism

I am repairing a Cannon MV600 which has had the eject mechanism forced and bent, I have now removed the cassette and straigntened the bent parts.
The mechanism is now moving smoothly in and out when power is applied to the loading motor.
However I do not know the correct relative alignment of the position sense wheel and the main loading camwheel.
There are some marks on the sense wheel (an arrow, a triangle and a stripe) and a small indent on the edge of the main camwheel.
can anyone help?

P.S. a photo of a stripped down mechanism showing the loading mechanism geartrain would be ideal
