What is the method of determining the ink level?

Sadly, the preferred method seems to be to "measure" the usage and then
arbitrarily determine that it's empty. �Oops, it's still half full...... too
bad.

There are dozens of patents where inductance or capacitance measures
the level.

I usually replace the cartridge when it quits printing.

Cheers!

Then why did you ask in the first place?

one way is droplet counting, often done by the printer driver.

Because there are dozens of patents based on inductance, capacitance,
resistance, ultra sound and other effects.

Generally one technology will prevail.

Which one is it?

Some are optical.

The cheapest one that the makers of the printer have access to the
patent on, and works well enough to satisfy their legal obligations.

What he wants is save money by resetting the ink level circuit. For the EPSON there is. But refills are messy and not realy good enough. There are solutions I believe it is called continious ink feed like mine 5 years and never failed it yet. Just every 6 months or so I just add some ink. It is cheaper to buy a new printer then to buy ink that is how they make money. I bought the resetter for $30 did it works it did but to do that for 6 carthridges every month was too much and to messy.

Generally, the one that people are willing to pay for.

Hope This Helps!

Reminds me. I must clean the print head. Yes, they're not combined ! The
cartridges are fine but the colours won't print. I obviously don't print
enought porn. ;~)

None. Nada, Zip, Zilch. Level is not determined or detected.

The worst ones count pages, and assume ink was squirted on the pages,
and stop printing after 200 pages, or whatever number.

The slightly less bad ones count how many droplets they think they have
squirted out, and call themselves empty when there's about 25% left
based upon the theoretical size of a drop and the fill amount.
