It could be fog. Often you need a certain minimum amount of exposure before the fog will become evident, which would explain the white borders.
One thing to keep in mind about fogging. Paper has a threshold, just like film. Once a paper is exposed, it will fog more readily than a completely unexposed sheet. The quarter test is fine for unexposed paper, but an exposed sheet has a lower threshold. tim
Inspect you enlarger from every possible angle - including from the easel area. You may be leaking white light.
I use the older kodak "bullet" type safelights with 8 watt bulbs. They point at the ceiling and have very dim output. One in the dry area and one in the wet area. Those bulbs look pretty big to me. Can you move them to a location behind the work area? tim
May be leaking white light? I have yet to see the enlarger that doesn't leak some light.
Joe, just a thought about what may not be "fogging" of the paper. Have you checked your chemistry lately? Is your developer fresh or has it "turned" on you? Can't help but wonder since your paper edges are still clean. tim
I have the same safelights as you do rolleijoe. I only have one though, but my darkroom is about 1.5 times the size of your enlarger table so it's plenty. It's in a in-ceiling fixture, however, so I get less light from it. But it works fine, even with Fotokemika Varycon.
One way to get fogged paper with clean edges as you say would be to keep the paper in the darkroom permanently. The chemistry fumes in there will fog the paper. Then during development, if the whole print isn't submerged all the way, but the edges are 'sticking up' and agitation is poor, then what happens to you could definitely happen.
Can you post a scan of one of the 'unhappy' prints?

That's what I've been doing, is keeping all the paper in the darkroom permanently (even fresh unopened packs of 25sh 16x20). When I put a print into any of the 4 chemicals, I make sure it's completely submerged, and then agitate the tray as well.
Unfortunately I'm still waiting on my scanner to arrive from eBay (old Agfa scanners went kaput with the company), and since switching to iMac, have had to start all over again in some areas.
But I will as soon as possible. I've had unopened paper in there for months as well as the box of 8x10 I used for test prints. The AC stays on all the time inside, which is why I left the paper in there. Where would you suggest I store the paper?
I'm about to order some Foma 542 and Varycon 20x24.
Thanks very much,

As long as you do not keep chemicals such as the smelly type of sepia toner whose fumes can (in theory at least) fog film and paper I can't see any reason not to keep paper in the darkroom. I keep most of mine in a spare fridge with my film in my kitchen but leave some (the larger sheets) in the darkroom without any problems.
Good luck, Bob.
