Judith, I am using a Canon BJC-265SP and am using a black cartridge. For this printer the only difference is that it will tell you there is a monochrome detected and ask a question.... can't remember exactly. I just hit ignore and the printing begins. I have used colour refills. bit of a giggle that!! They work fine but the refilling can be a challenge.
