HP F2280 Paper Light Flashing and won't print?

HP F2280 had a paper jam, I got rid of the paper, it did not rip so there is nothing left inside. I've unplugged the power, usb and restarted the computer. I've even had it upside down incase there was something stuck in it. But the paper light is still flashing and there is the letter E where the numbers for copying usually are. I've been at this now for 2 hours, please help? And yes, I have put the paper back in.
