Operator error yesterday as I lined up the wrong black line on the plastic scale rather than the center line. Yeah, how hard is that to miss? Since I don't use my Domino everyday... uh wait... yes, I don't fire up the Domino every day 
... it would be good do clearly differentiate the centerline against the left and right markers.
