Epson Stylus CX5400 Printer Error

I just printed 100 pages and after it finished I got a printer error that says on the screen: "Printer Error----See your documentation and call service if necessary". The manual says turn the machine on and off, and that did nothing. I only use Epson print cartridges. Any ideas??

I am afraid if I take it to my local dealer (40 miles away) it will cost more to fix it than to replace it.

Thanks
