my first guess, was a surge.. are you sure your power surge protector is still good.. thats the only thing I could think off.. unless coincidentally the power button on the printer is like jammed... I'd say, if your still under warrenty to return the printer. If your out of warrenty take it apart and look for a jammed power button..
Thats All I can think of.. but your probably best off buying a new printer.. seeing how most printers are sold cheaper than the ink for them
