Here is the link for all the documentation, troubleshooting and drivers for your printer. http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?oid=58773&prodoid=56291070&infoType=Downloads&platform=Windows If you go through the troubleshooting guide, hopefully you will find an answer - with the info you gave I had no luck, but the procedure is quite detailed, so you may have more idea what answers to give. The next thing to try is to uninstall and reinstall the drivers - on the link above you can download the latest versions. This ,may solve the problem and is simple enough to do (ask for more help if you have trouble with this procedure). The only other thing that maybe worth doing is to give the whole machine a gentle shake just in case the scanner carriage mechanism is somehow jammed - sometimes a shake or a slap can free this. Hope this helps, if not please post again :)
