I was re-ordering the list view based on replies and noticed this got 2.7k views and zero replies! How embarrassing!
The Type 2 is a very stiff paper. This combined with the rubber loader tongue on the Epson 3880 can make it difficult to load. What I do with this paper is gently push from the back middle edge of the paper as the paper is fed into the printer. It should be a firm but gentle push (not so hard that it buckles the paper or make it miss-aligned.)
Make sure to clean the tongue with alcohol regularly (it can get slick and not grip the paper properly).
An alternative is to use the rear feed on this printer.
