I have a Dell V515w printer (operating w/Dell Studio XPS & WindowsVista) & all of the sudden the color ink cartridge will not print. I have tried EVERYTHING! The cartridge was not empty or low, but I replaced it with a new one anyway out of desperation, but still no luck. I have taken it out & put it back in, as well as the printer head too. I have cleaned it, deep cleaned it, unplugged it, aligned it, and followed tons more of the help/troubleshooting instructions as well & nothing has worked. Regardless of what setting it's on (I've tried them all) only the black will print. If anyone can help, I would GREATLY appreciate it. Thanks.
