Only when I print on 8.5x11 paper (Hahnemuhle Ultra Smooth). When I print 13x19 or 17x22, prints are ok. But today (not yesterday), when I print 8.5x11, the image prints OK but on the right side there is a triangular image of part of the image area at a angle with a vertex at the lower right corner. It has gotten more pronounced.
Also, when the print is nearly done, the printing sound changes; I hear a "whooshing" sound for a few seconds. The image is what I see.
Paper width is 5; platen gap is wide.
