I like John Heisz' way of getting things done:
The U052 Canon printer error can be fixed in the following way:
"To try and resolve the U052 error, please remove and then reseat all of the ink tanks and print head in the unit. Next, please turn off the printer, unplug the power cord from the back and leave it out for at least 10 minutes, then plug it back in and turn it back on."
Or, when that doesn't work, there's always the stake maul fix.
