I replaced my Black and Yellow cartridges at the same time. Yellow is not coming out at all... it's all black. I set up a graphic image file, an all-yellow canvas. First printing is all-black. second printing gives me a small amount of yellow, mostly black. 3rd, 4th and 5th printing a little more and a little more and a little more yellow. Same for the 7th 8th and 9th printing. I'm getting to an almost faithful representation of the yellow color in my canvas.
Next day we are back to printing all black for the yellow canvas. I've cleaned the heads and pulled out and re-inserted the cartridges several times now. To say I'm upset is a gross understatement.
I have always used genuine HP ink cartridges in my HP Officejet Printers. Other than the fact that it is rather expensive, I am satisfied with the XL csrtridges.
