The problem is that the 980cxi on Black always with the color cartridge "over it" prints (which by the way HP is an impertinence) and then take the cartridges are not exactly in the same place, then it will not stop.
The cartridges work well individually, but together not, at least not on my printer. On Windows XP can be with the settings still enforce that only the black cartridge is used (completely hidden of course), in Windows 7, there is this setting but not over and over again to print fire up the old box ...
Two stars, two because the cartridges after all work individually and the third for the price.
