These claim to have a 4000 color page yield. I used them for printing primarily color text and outline shapes. I also have a black only laser, so I don't use this for printing black specifically. The entire print count for this color printer is 907 pages. The cartrdridges that came with the printer originally were very low yield. And these are no better... approx 500 pages yield. Also, the yellow cartridge has had major leaking. See attached photo.
