Do I have to replace a color ink cartridge?

I am trying to print out some of my school work in black ink only, but it keeps telling me because the blue is out it will not print. Do I have to replace the blue, I do not print in color anyway, I always use the draft print to save ink. I print a lot of stuff for school, but now it won’t let me. Anyone know if I really have to go out and buy a color cartridge? My printer is an Epson Stylus CX7400.

I don’t think so. what i do is go into the printer and remove the color cartridge and close the printer and then turn printer off and then turn it back on. Once you have done this, go to printer properties and it will recognize that the color cartridge has been removed and it will need you to confirm it, that you only want black and white. once you’ve done this, it should allow you to print in black and white.

Hope i helped.
