I'm looking at this link:
And step 6 says:
"Switch on enlarger light to make the print. Place a piece of used print paper white-side-up on the easel and focus the image. Create a border around the image by sliding the easel arms up to the edge of the image so it just overlaps."

I'm a total newbie, could someone please let me know if this is accurate? Do you turn on the enlarger light? (I thought paper was sensitive to all light), and is this totally wrong when it says place a piece of used print paper on the easel? Why used?
