I'm pullin my hair out over this one issue. And it's hard to do seeing as I don't have any. That's how rough it's been.........
I'm running OSX 10.4.6 on a 2.7Ghz PowerMac, using CS2. When using my defunct 2200, I'd swap to Matte ink, delete the printer from the Printer list, re-start the computer, re-add the printer, and then I would get Velvet Fine Art paper (in black) in the Media Type menu. It was a pain, but it worked.
Several hours of tech support from Apple and Epson (great people, btw) yeilded no resolve to the problem I am currently having with my new R2400. I can not get VFA to come online in the media type menu. I've reinstalled the driver 3 times, reinstalled the ICC profile from Epson's site twice, and still, no VFA (still grayed out) in the media type menu.
I won't kill mysef over this one as there are many work-around options to this perplexing issue. I tried switching to "rol media" as previously suggested, but to no avail. Any other thoughts?
