I ran the firmware update tool from programs. It starts searching for "target printer" but i keep getting the message "target printer can't be found" My printer is ON, connected and in printing mode ( "online"). What am I missing?
Are you connected by USB or ethernet? If USB, are you connected through a USB hub, and how long is the USB cable? A long cable or USB hub might cause problems (just guessing here, I don't think we have any actual reports about this).
Also, when you have this kind of problem it is always a good idea to power cycle the printer. I have had some (rare) problems where the firmware got into a state such that this was the only fix.
PS You are getting pretty close to needing to put in a call to Canon tech support if these questions don't help you resolve the problem. Let us know the outcome so we can add the information to the Wiki.
