I was given a printer to see if I could get it working (it's second hand and no one knew whether it was working or not), I installed it all correctly (had to download the drivers as I didn't get a disc with it). Everything works fine, except it won't print black ink. I checked the ink level for the black and it was almost out, so I figured I'd replace the cartridge with a new one that came with the printer. However that didn't work. It just does not print black ink. Any ideas on this? It would be really nice to be able to get it working properly as there is nothing else wrong with it.
