I bought this economy pack hoping that it will work on my printer but it doesnt calibrate and doesnt align the cartridges. Now the result is that no black or colored ink coming out in my print outs. It doesnt wanna print.
Increase the level of the black ink in cartridge as full as red, yellow, blue and photo cartridge. If it take another teaspoon of ink to bring level up, HP do it. I thought I would get a full cartridge in black but did not.
The ink quality is very dark and prints crisp quality documents without smear. Only drawback was not printing enough number of prints from a cartridge.
