Well, just as I was really getting to like the Epson 3880 problems seem to be starting.
I have been trying to load different papers 17x22 through the rear manual feed, however each time it comes up error and stats remove paper.
Have followed the instructions on pages 34-35 but still no go.
Now I have also found out that Media Type "Fine Art Paper" is grayed out.

Any idea how to get the rear manual feed to work and why the Fine Art Paper is grayed out?

Thanks!

Looks like I figured out how to get this rear manual feed to work.
On the printer itself I turned off paper check.
Nowhere in the book I found this unless I missed it.
But anyhow I am happy this is now working.
Also the Fine Art Paper settings are not grayed out once I was able to get the rear feed to work.

The front feed works well for Fine Art paper, as well.

Thanks! I have not yet tried that yet.
It took be a while to figure out the rear manual feed.
Now that I have done that it works great.

I missed that too. Where and what is it?

I think it's under the Printer Setup section.

On the printer itself click on the Menu button then Paper Size Check then Off.
I just happen to find it and it worked and the rear manual feed stated working.
