Does anyone have a diagram (or detailed instructions) on "actually" using the X/Y values and axes for printer calibration? In the instructions, you print the Calibration Sheet, fold the paper in half, fold it in half again, open up the Sheet back out and where the center of the folded part is where the printer thinks the center is. It is at this point, I get stuck. If I wanted to, say, move the center point "up", what values do I enter? Your assistance on this would be highly appreciated.
