my Kodak ESP 5210 printer started playing up this weekend. It takes the paper in but instead of printing just spits it back out again blank. I've tried different sorts of paper and I'm not just using a single sheet and am fanning it first. It prints a test page fine. It prints documents that I have in "Word" but if I try and print anything else it just expels the paper. No error message or anything....in fact it acts as though it has printed it. I've unplugged it. I've uninstalled it and installed it again. Any suggestions?
