Maybe it's just me, but I have trouble printing 4x6 photos on the 3880 -- they often come out slightly crooked. Sometimes I can get them straight, sometimes not, and it's frustrating. I think the problem is that if you place the left hand "thing" at the very edge (left hand vertical) of the paper you're feeding in, then you get a paper feed error. You need to leave a bit of wiggle-room there. Whatever the printer does to straighten the feed path of paper once it's taken up by the machine, a 4x6 sheet seems to be too small for the printer to handle well. I've actually unearthed an old 2200 to print those small photos for family and friends to avoid this problem. On anything larger, the 3880 turns out beautiful results -- certainly a noticeably sharper image than the 2200. (I realize you're comparing with the 2400, not the 2200, but I imagine the 2400 handles small sheets well, too.) --Barbara Armstrong
