Just wanted to let you know that my printer is working again.
One of the suggestions I read was to unplug the printer. Then while plugging the printer in again, hold down the "print photos" and "cancel" buttons. Release after 2 seconds. When I tried this the following is the result I found:
If the "print photos" and "cancel" buttons are both held down when plugging the printer back in and released after 2 seconds, the printer does not continue to cycle. At this point the blue light near the camera sybol, and the power button remains lit, with no display. If you press power button at this point, it begins to cycle on/off/on/off again.
Feeling frustrated with nothing working, I tried again. Held down the "print photos" and "cancel" buttons while plugging the printer back in, then release after 2-3 seconds. Once again, the blue light near the camera symbol was lit along with the power button, still nothing on the display. I then decided to give up, and I left it still plugged in with the blue light on and power button light on. Two days later I happened to be near the printer and touched the display. To my amazment, it was working! Just like nothing had happened to it.
I'm not sure this will work for you but it's probably worth a try. Good Luck!!! Let me know if you get yours to work.
