Had the same problem a while ago.
In my case it was simply that the plastic tab had come away from the plastic strip you're supposed to pull out from from the cartridge before installing. Found the end of the plastic strip and pulled it out and this sorted the error.
An additional problem we had was alignment of the colours when printed. Magenta and black were misaligned by about 0.5mm after changing a cartridge. This was cured (after much frustrated cleaning/calibration) by switching the printer power off and on (couple of minutes to cool down).
Hope this helps.

I have a similar printer, canon LBP 5000, with the same problem.
I contacted Canon guys and explained them the problem. This is what they said:
this problem occurs in either of the 2 situations:
1. when your colors/toners have gone or nearing empty.
2. when you have REFILLED your cartridges.
Need to replace cartridge (which costs really tooo much).. its sad!
For me it was the first case, but, un-really-fortunately, I REFILLED the cartridges (this is al b4 contacting canon guys). And still the problem persisted (so now even the 2nd case).. After finding out that i will have to replace the cartridges.. i'm really confused whether i should do it,, or buy a new printer instead.! (since i've already spent and wasted quite a lot of amount in refilling the colors :( )
So, please DO NOT refill the cartridges if u god-forbid come across this problem ever. Go replace the cartridges. (unless n until someone else comes up with a solution atlast!)

I solved this problem.
You need to bring your printer to some service, and perform cleanig of the printer's optic instruments, which are most probably coverd with dirt, and printer just can't recognize catridges, and can't give you the best print quality.
Just take it to the people who refill toners, or to some official service, they'll know what to do. I had the same problem as you, and today I can't recognize how better print quality is, and more importan, printer is not asking calibration any more.
