I believe that the problem is that in the winter with the humidity your paper is slightly curling. I have an Epson photo printer and am having the same problem. Sometimes I can get around it by turning around the paper so the bottom edge is now the top edge. Or what I do is load fresh paper in before I start to print. Also you can try to slightly roll the paper back to get rid of the curl. These printers are very temperamental and the winter always messes them up. Hope this helps
