It is suggested you use a driver update/install tool to get the printer driver downloaded and installed. I use Driver Talent http://www.drivethelife.com/. After I got this tool, I don't need to search drivers online and install the driver manually. You may have a try. Well, this is the SX405 printer driver download address:http://www.epson.co.uk/gb/en/viewcon/corporatesite/products/mainunits/support/2782?supportLandingPage=true
