I had the same problem. It is most likely that your print head nozzles are clogged. Your choices are to attempt to manually clean them, or order a new print head from Canon.
Attempt the manual cleaning at your own risk, this doesn't always work. When it does not work, it means your print head is damaged.
To maually clean the print head. Printer cover up (so you can get to the cartridges and print head). Turn the Printer Off. Remove all the cartridges (I put each cartridge in a separate zip lock bag). Then flip up the lever and remove the print head.
Now heat (don't boil) distilled water (Iused a good sized cook pan and a plastic measuring cup to pour the water). Find a container you can soak the print head in (I used a deep alluminum baking pan). Pour the hot (not boiling) distilled water over the print head molding where the cartridges seat down (hold the printhead over your diposable alluminum pan). Then dunk the molded print head part into the pan numerous times. When the water gets dark change it (be carefuill not to stain the sink). Then slowly pour the hot distilled over the print head (opposite side from where the cartidges seat in). Eventually no ink will be in the water. Set the print head on a dry paper towel, and let it dry for 24 hours or longer. Reinstall the print head, then the catridges. If it worked, your true colors will return. It make take up to 15-20 photos to get all the ink catridges flowing-be patient. You can also just wait 24 hours after re-installing the cartridges, and hopefully it will take less photos to see the correct color match.
Never keep printing when a cartridge is low or out.
Print a few prints every week. Not printing for weeks causes the printheead and the ink flow to clog!
Good luck. I just recovered my S820 and my i900D using the above cleaning method. Like everything else, your mileage may vary! It cost me $1.29 for distilled water and about an hours worth of time!

hi there,
The dreaded U052 error means that the 'chip' fitted to the
Cartridge is not responding .. Canon (like all printer mfgs) makes all
it's profit from selling Ink .. so they fit these chips to try to
prevent you refilling or using a 'compatible' replacement cartridge
You
have to move the chip from the Canon cartridge to the 'compatible' and
(it seems) the chips are particularly sensitive to static / damage ..
many people end up blowing the chips during the swap over .. or even
when fitting the original genuine cartridges to a brand new unit for
the first time ...
If the unit is brand new, take it back and demand
a replacement ... if you have just swapped over the chip onto a
compatible cartridge, you can try buying a genuine Canon cartridge
(which will have a new chip) = hopefully that will do the trick

you have a purge unit problem, cost more than the printer is worth unless it is under warranty,
