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.
