Yes, it's the Epson Media Installer, which apparently isn't working on my computer right now. Go figure.
OK, that helps. Once you are able to launch the program, find the Epson paper that Canson recommends as their “media type” for your Canson paper. Copy that, and the “edit” it - starting by entering the name of the paper at the top of the edit window. Then, take some calipers and measure the actual thickness of the paper (VERY often the Epson media type paper can be very different in thickness [caliper] than your 3rd party paper.) Then “browse” to associate this new custom media type with it’s ICC profile (assuming you installed it on your system first, as you should do). When done, just save and “register” it to the printer. Oh, and the printer must on to do this.
Now when you go to load the paper you can “load it by its actual name” that you gave it right on the LCD panel. From that point on, any tweaks you make to that paper type via the LCD panel on the printer will “stick” until you change them. E.g. Platen Gap, drying time per pass, etc.
I’ve owned a bunch of Epson printers, and when I was first “forced” to learn this with my new printer (7570) I hated the idea. Now, however, it is a very cool way to do this. I don’t have to “remember” a bunch of Epson media type to go find and adjust other stuff on each iteration of use. It’s pretty slick.
