When you have the power off you can't see any of the buttons light up. Ok button only lights up when power is on. I tried this and it didn't work.

Turn off printer
Disconnect from AC
Press OK button on printer 5 times
Turn on printer
If this does not work
Try several more times
If it still does not work
Try again but do not turn on printer until next morning
This has worked for me twice so far.
Also you might try removing the print head and rinsing under hot water until water runs clear before you start the above procedure.

After speaking with a Canon representative that told me I would have to just buy a whole new printer I was willing to try anything! Thank you so much for this solution, Canon should really be willing to try and help more than they were today. I was very disappointed with their customer service.

I had the same experience with Canon help. Useless. Tried the methods mentioned here and they didn't help either. So I've ordered a new printhead. Lessons learned. (1) Use the printer at LEAST once a month, even if only for a test page; (2) If leaving for an extended period, do a cleaning BEFORE (and THEN shut it down); (3) DON'T ever let a cartridge run dry.
I'm pretty sure I'd have gotten more life out of the printhead if I hadn't violated all three...
