Query: HP K5400

I've had the HP K5400 for several months now. I am disappointed in two things, it seems to eat ink, I'm always running out of one color or another. I'm just a home uses so I don't do a lot of printing. Second when I've run out of one color and want to switch to just black, it won't let me do so unless I replace the empty cartridge.
