A footnote after two days with the Photon... yeah, there's an odor after all. Not offensive, to us, at least. We returned from lunch this afternoon just in time to catch a batch of prints finishing up. Walked thru the studio front door and "Oh, there is a smell," shrugged our shoulders, and went back to work.
Thanks to all for the advice. Minor glitch on the first run, but after cleaning things up it seems to be doing what it was designed to do.
