How does my Epson Photo 750, or any other printer, know how much ink is in the cartridge?

I'm asking because all my recent prints on PhotoPaper are skewed toward the yellow. When I do a print test the red and blue inks are absent. Two explanations are clogged nozzles, but repeated cleans make no difference (so they could be very clogged). Alternatively I could have just used up those inks. But the status monitor says I still have what I guesstimate to be about 10% for all colours. How accurate is the printer/software in assessing ink levels; or more interestingly, how does it measure?

If you have a replacement cartridge, you might swap it in so you can look at the old one. Then you'll know what the situation is, for the future, no?
Is this a good place for an argument?

The HP deskjets use software to see how many pages have been printed and then estimates how much ink has been used.

My Epson Photo 870 tells me the ink levels. I just open up any document and go into the page setup. That brings up the printer info. There is an icon of an ink cartridge. I click on that and it shows me how much I have left. As I get near the end of a cartridge, it tells me how many pages like the last one printed are remaining in each the color and black.
