If it's like mine (I have Magnifax 3, an older model), you just pull the neg. carrier halfway out, and then on the baseboard you'll see a projected bright line. Focus until the line is straight (unbroken). It's a bit difficult to explain without a pic. You could try www.meopta.cz - they have some manuals online, and I think the manuals have photos of this "gizmo".Originally Posted by Snapper
Surprisingly, this fosucing method works quite well.
