Canon (iP-4000) Ink Status monitor

Archived from groups: comp.periphs.printers (More info?)

Canon uses an optical status monitor, and it will tell you when the tank is
empty, nothing else. It'll also stop printing when the sponge is empty.
If you want to know how much ink is in the tank, open the printer and look.

If you look at the diagram you'll note that there is a prism at the
bottom of the tank. I'll read full so long as you have more than 20%
ink left. You can continue printing as you have a bunch of ink in the
sponge. But this is your you should buy some ink now warning.

It's not a problem so long as you understand that your down to your
last two or three or so full color pages, or your last 50 or so light
use pages. Other printers give you an estimate based on how much ink
is used... and that system is part of the new canon printer.

The ip4200, and I suspect the ip6600D, the Pixma 500/800, of which the
ip4200 only exists in north america presently.

The drawback is it uses chips on the tanks for the estimate effectivly
limiting you to OEM ink. This would be the new cli-8 inks.
