Canon iP4000 and ink alert no accurate

Seems like the Canon iP4000 printer has a ink reservoir alert system that
shows a picture of the ink left by colors. Unfortunately, there is no
gradual dropping of the ink in the alert window. One day it looks full and
the next you are being warned to replace the cartridge. What's up? Is it
software or perhaps its not getting an accurate measure of how much is left
in the cartridge.

The cartridge in the IP4000 has two compartments. An ink (liquid)
compartment and a sponge compartment. In the liquid side (OEM
cartridge) there is a tiny prism on the bottom, there is a light that
shines thru the prism. When the liquid side is empty, it alerts you
that it is empty. There is still 'some' ink in the sponge side, but not
wise to print much after the liquid side is empty.

Nope. That is the way it works. There is a
small prism at the base of the free ink part of
the cartridge. Nothing happens until the ink
drops below the prism and then a sensor is
alerted. There is no continuous monitoring. If
it looks full one day and then shows empty the
next day, someone did a lot of printing or didn't
look carefully at the tank.

And they're sooooo easy to refil! Just drill a little hole or heat up a
straightned paper clip and melt a tiny hole, refill the cart up and then plug
the hole.
