Try to open and close the main cover a bit, ... ink recognition will start and may solve the probleme ...
... otherwise remove the cartridge and clean the chip contacts e.g. with spirit
Maybe also pressing the stop/reset-button for >10s will also help to continue printing, but in this case the fill level of the cartridge will no longer be shown

I had the same problem. My mp630 is also only 4 months old. I replaced all colour ink cartrdiges(inc black), but was only able to release the function for detecting the ink levels for magenta and cyan. Yellow and black then started giving error message U043, with them alternating between working, but never working at the same time. Getting them all clicked in with the lights glowing red does not solve the problem, as once the printer cover is closed, the same error message turns up. The only thing that worked for me is moving the chip slightly out of alignment, by pushing the sliding chip holder, and I only had to do this twice before they all started working and the printer was unlocked.
Same problem - two solutions I found helped me work out mine. One said contacts needed to be cleaned and it worked to use a Q-tip and alcohol or just click it in position several times until it recognizes the cartridge - this may work. Another said that they got it to work by installing a brand new cartridge - cool, but I have one full of ink it won't recognize. So I pulled the little circuit board off a used cartridge (like you need to do with some refills) and put it on the cartridge that it wouldn't recogrnize - works great. Still haven't figured out how to get it to acknowledge ink levels though. Canon really should be more consumer friendly since these problems seem to be intended to compel the use of proprietary cartridges.
I have a canon mp510 pixma same message U043 and a u150 fault. I cant see any chip to replace and have replaced my original cartridges with a non branded cheaper type, this might be why. Does this make a difference or is this the same problem occurring with replacement canon cartridges as well.
Dont want to buy genuine ones if its not going to make any difference.
I had the u043 problem on the blue cartridge on my mp830.
I was using non-original replacement inks but re-using the chips from the originals - replacing the blue cartridge would cause it randomly work but i then noticed the chip holder was not centred so I realigned it and hey presto! the problem was solved first time.
