HP 6940 Ink Supply

About three weeks ago I got indications that the ink supply in both
tanks was low, yet I keep getting excellent results. Day after day.

Is HP telling me it is 'time' based on the actual ink supply, or it is
'time' based on the fact that I have been using the printer
(moderately) for almost five months and they want to give me a nudge?

How much advanced warning of no ink can one expect.

Incidentally, I do like the printer. Good photos and text. Oh, are the
cartridge refills at Office Max worth the price?

Thanks.

Thanks Bob. Makes a lot of good sense. And I'm still printing...and
have a drawer full of replacements.
