Wondering if anyone else has one of these machines - mine is the DX7400. Printer's wonderful in comparison to my previous Stylus color one, but the scanner is causing me problems. I'm trying to scan handmade greeting cards which have 3D (deep) images on them - however, while I think it possibly did scan these ok the day I got it or shortly afterwards, now I'm finding it routinely does so but they look as if the lid wasn't tight (which it isn't!) and also the image will be sharp, but the text on the card itself will come in blurred. I appreciate this is obviously a distance issue but wondering if anyone knows anything about how to overcome this through settings etc?? Any help would be extremely appreciated. TIA, Romayne
