My HP C3100 printer will not print when i put the black ink cartridge in, and it has a E on the LCD?

But when i take the black ink out it prints but the lights flash saying its out of black ink. I tried uninstalling and installing the drivers but it doesnt do anything and i also tried a different cartridge and it still didn't workMy HP C3100 printer will not print when i put the black ink cartridge in, and it has a E on the LCD?
It sounds like a problem with the ink cartridge. Did you just change the black ink cartridge and it started doing this? If so it may be that you need to perform a head alignment, because it sounds like it is printing, just not black. Try the head alignment and if that doesn't help, do a nozzle check and head cleaning, if indicated by the nozzle check. It shouldn't be a clogged printhead, since you have a new ink cartridge.





I am assuming that you are using HP OEM ink cartridges and not refills. If you are using the refills, it raises a whole new set of circumstances. The printhead may more than likely be clogged, since these ink cartridges come with a built-in printhead and if you are having them refilled, then the printhead may be worn out. Also, the inks are not the same as HP OEM cartridges and may lead to printhead clogging.





If you are only using HP ink cartridges, I would say do the head alignment. If you are using refills, then try the nozzle check and head cleaning.My HP C3100 printer will not print when i put the black ink cartridge in, and it has a E on the LCD?
You should make sure the cartridge is full. I'm just guessing, but I think ';E'; stands for ';Empty.';
