In my computer I have recently upgrade operating system from windows Vista to windows 7. After upgrading operating system all the things worked correctly except HP photosmart c5180 printer. When I try to print anything from HP photosmart c5180 printer at that time I didn’t get any problem but when I try to scan document at that time I get error. I have turned off my HP photosmart c5180 printer and then removed power cable from it, after doing that I have plugged power cable in my computer and at the back of my printer and when I tried to scan document again at that time I get same problem. I have also uninstalled all the HP software’s from my computer and then I have installed it again but after doing that also I am experiencing same problem while scanning the document. What should I do to resolve this problem?
