There is no sensor involved with the ink cartridges for this model. Just a
count of ink used by the printer from each cartridge, as Zakezuke said the
printer works out how much is left in the cartrdige based on how much ink is in
a full cartridge less the amount used when printing and when the printer does a
cleaning cycle. At an appropriate count the printer reports the low ink
condition and when a new cartridge is installed the count is reset by the user
as you have descibed. The count is quite accurate and results in very little
ink left in the cartridge.
Just wondering. As I mentioned, I put in a new black cartridge a few
days ago and the screen message asked if I put in a new cartridge and I
put a checkmark in black cart to indicate it was replaced so the printer
can reset. I printed quite a lot of text pages since then so the black
ink level should show on the screen that its used some ink by now, but
it still shows full. I know the color should show a lot less, but as
you said, probably because I switched printers and its the same color
cart, it will still show full, but the black cart was installed after
I got the new printer. Do you think that both carts have to be replaced
before the ink counter works properly and is the ink counter something
that often may not work properly? I think I can live without the ink
counter if I had to, but its a very convenient feature and I'd rather
not.
