I had to put this project on the back burner for a while but now I am
back to it.
In stefen's article he refers to the "optical paper sensor" and
states this is "glued to the side of the paper slot...." and shows
this picture.

I cannot seem to locate the optical paper sensor. Furthermore, is
the picture above where the sensor is located originally, or do I
need to move it there from some other location?
In any event, I cannot seem to locate the sensor anywhere and it
definitely is not glued in the spot shown in the above jpg file.
Any help would be appreciated.
