The way I make decals is to NOT use the whole sheet of paper. I make a pencil mark on a piece of paper in the tray so I know which way it goes through. Then I print the decal on paper. Cut a piece of decal paper that's big enough and tape it to the piece of paper. I suppose it could cause a jam, but I've never had a problem. I haven't printed a heck of a lot of decals either.
