How to print with just black ink

Hello! So, my color ink is out and I do not want to buy another one. I just bought black ink for my Canon Pixma TR4520 printer, serial number KMJA61724

I had this problem before and I know there is a way to use the printer keypad to input a code to print just black ink. Ive tried selecting black and white only on the document, Ive tried looking at the Printer Settings on my Mac but there is no option to change to black ink only. (There is only a tab for General and Supply levels).
