I have a V515W all-in-one. I never use the colour ink cartridge and now it has dried up. Which is fine, because I don't need it. But now I cannot print using only black ink? I just got my new black ink cartridge today and it keeps telling me to replace the colour ink, even though I have the printer set to print only with black ink and I there is no colour in my documents. How can I make my printer realize that I don't care about the colour ink and I want to print only with black?
