A faulty connection, perhaps?<g>
Try swapping the cable with another one
OTOH, it could simply be that multiple attempts to install the printer
drivers have confused the PC - try this.
Power down the computer, and disconnect the printer
Boot to Safe Mode
Remove ALL Epson Printer drivers both from Settings|Printers, and from
Add/Remove Programs
Reboot to Normal Mode
Check that there are no printers remaining installed.
The begin the installation again, from the start, following the instructions
EXACTLY.
