I did what you suggested, nothing happened. I then discovered that the power card was disconnected. I didn't know it had pulled out when i move the printer to clear the jam. I plugged it in and it booted up. This was an expensive lesson! Thanks anyhow.
The answer was in the right direction but maybe you should have first suggested making sure the power card was plugged in then add the next step of unplugging it and holding down the start button for 30 seconds. Your suggestion got me going in the right direction however. Thanks again.
