What should I do if I see the message Scanner Not Ready?
Do the following:
Make sure your EPSON Stylus CX5400 is turned on and securely connected to your computer or USB hub.
If your EPSON Stylus CX5400 is connected to a USB hub, make sure it's connected to a first tier hub. The first tier hub is the hub closest to the host computer when more than one hub is connected to the computer.
Check to make sure the scanner lock is unlocked.
Make sure you turn on the EPSON Stylus CX5400 before you turn on your computer.
