I've had nothing but trouble with this unit. If you run out of ink of any color you can no longer print. This means if you run out of yellow you can no longer print even black and white documents or in grayscale. I've had my printer tell me numerous times that there is no cartridge even though I had just replaced it, which also prevents printing. You just have to take it out and reinsert it until it finally decides to accept your ink.After only about a month of use it sounds like a freight train filled with forks and chalkboards screeching to a halt every time a piece of paper passes through it.
