This is a known problem with some Epson printers such as the 2400, 2800, 2880 and R3000. The solution to this is to tape your sheet to a larger sheet of carrier paper. In my case, I tape an 8.5x11 inch piece of Pictorico to the center of a legal-size sheet (8.5x14 inch) and center the image in this larger area. Anything in the first or last inch or so of the negative will have this problem and this is the only fix I am aware of.
