HP 2840-Brand NEW yellow Cartridge shows LOW INK

This is the 3rd cartridge (yellow) that I have bought and they are all HP Brand New sealed in box Cartriges-They all 3 show LOW ink. So I went ahead and let one run till it wouldn't do anything anymore and only got maybe 300 pages out of it. So the 2nd one is the same exact way. I'm on my 3rd cartridge and it reads the same way as soon as I put it in. Does anyone know why? If the yellow cartridge goes out then my printer won't even print straight black pages. Any ideas what is wrong or how to fix this issue? I have read and read till I'm blue in the face so now I'm trying this. Thanks!
