You could have either a flawed cartridge or it's installed improperly. Take each cartridge out, examine it carefully, put it back in to see if you can identify the offending cartridge and check to see if there's a protective film of some time still attached. If you know which one is causing the problem then try swapping it out with another to see if that solves the problem.
