This information originally from: My printer Canon MP530 stopped working with an Canon Forum (also has a walk through for removing the printer head and ink cartridges.)

Just so you know, the 530 and 550 are the same machine, except the 550 has a few small improvements.

Solution 1:

• Remove and replace the cartridges.

Solution 2:

• Insert new cartridges

Solution 3:

• Reseat the print head to correct print issues or clear an error.

Solution 4:

• The print head is broken and it must be changed by a new one.

U052 is a temperature sensor in the works below the cartridges. Canon can ship you the part; it's not the inks cart, but then it's not for me to say 5 minutes with the power off or 20 with either a solvent cartridge (especially on any colors with stripe dropouts) or cleaning the works and reseating flex cables won't fix it. (Take it to a Canon shop per any surviving repair warrants; it's serious enough.)

Per Canon's website, and this just worked for my mp620:
Turn the printer on.
Open the cover.
Remove the ink cartridges.
Remove the printhead.
Re-install the above (this resets the printhead).
Close the cover.
Printer should initialize and go to home menu screen.

Dear dgthorpe,
This indicates that printhead of your printer faulty. Commonly this problem come with short circuitry problem in printhead so it may harm logic board and carriage unit too. I suggest you to try checking with another printhead first.
Regards,

It's most likely an after market cartridge. Try a diiferent one or get the OEM.
