To close out my Sep 20 post above, in case anyone else experiences this problem, here's how Canon helped me fix the case of the missing Fine Art Smooth:
There were two related problems we were trying to solve. First, I didn’t have the FineArtSmooth icc. Second, in the Media Type pulldown, I didn’t have the Premium Fine Art Smooth media type under Fine Art Papers.
The tech and I walked through the list of media types, and I had every single one except FAS. We confirmed that the problem wasn’t a LR problem because it occurred in LR, PS, Preview, and Powerpoint. And I had every other Canon paper icc profile except FAS.
It was an odd process. He took me through a couple of normal exercises (which I had already tried, but tried again in case he did something different): re-loading the driver, re-updating firmware. Each time, we closed LR, rebooted the Mac, but no cigar. I think what finally did it was the Canon Media Configuration Tool, which is normally used for adding new 3rd party papers but we used it to add the FAS media type. Again, closed Lightroom, rebooted the computer, but no change.
He was stumped and said he needed to talk to “engineering” and he’d call me back. He never did call me back. But, after lunch and a final desperate reboot, somehow the FAS icc and media types showed up. All I can think of was that the Media Configuration Tool did the trick, but for some reason it took TWO reboots for the change to take hold.
In any event, I was generally pleased with Canon support. I'm pleased with the PRO-1000 so far. And FAS is a nice paper.
