Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
That is not possible, your printer requires a black cartridge and a color cartridge. You cannot use 2 of the same.
you can insert the color one when the printer calls for it, and save the 2nd one for the next time a replacement is needed, or return it and get the black instead. But it requires both.
I can give you a link to order the right cartridges if you can give me the model of your printer.
