Ink savings can indeed be substantial:

If you look at my EEPROM info sheet example, you read correctly. At
the date of printing (Oct. 12/2006), this iP5000, my first, had 8,294
pages on it. I generated this particular page to document the stats
when it's first printhead wore out. On close inspection /
magnification, the pigment black (BCI-3eBK) nozzles were flattened and
worn from use, so a new printhead was required. If you look at the
cartridge count (CT= in the first paragraph), you'll see it used 13 x
BCI-3eBk pigment blacks, 4 x BCI-6 black, 9 x BCI-6 cyan, 10 x BCI-6
magenta, and 10 BCI-6 yellow. Only the initial, factory-supplied set
were Canon OEM. After that I used nothing but CoralJet non-OEM
cartridges, and I've used enough of them over a long enough period of
time to be completely satisfied that they're functionally equivalent
to OEM for my purposes (mainly plain paper colour printing).
Regardless, that's a total of 41 cartridges at $1.80 each, or $84.87
including sales taxes, or about a penny a page. If I had purchased
Canon OEM inks, the total cost would have been $943.00, or almost 11.5
cents a page! That's a HUGE savings of $858.13.
I have a 2nd iP5000 on which I do most of my personal photo printing.
It now has 1246 pages printed, of which 133 are photos, and 45 are
CDs. So far, I've only had to replace each of the factory OEM
cartridges twice. That's 10 cartridges at $1.80, or $20.70 including
tax, or about 1.6 cents average per page. If I had purchased Canon
OEM inks, the total cost would have been $230.00, or 18.5 cents
average per page. Savings: $209.30.
That's over a thousand dollars just between these two printers!
On the 1st iP5000, I've since replaced the waste ink pads, reset the
waste ink counter, and now, with 9,878 pages on it, 1,874 of those on
it's 2nd printhead, it is still going strong, and it still prints
perfectly, even photos! I also have 2 more iP5000's in my family,
plus 2 iP5200's and 1 iP5300's. The 2nd and 3rd generation iP's also
use CoralJET cartridges, with the factory chips transferred, and ink
monitoring disabled for now...whoop-dee-do! I can re-enable it if a
chip resetter ever comes along - service mode rocks!
Great idea of trimming that plastic away to see the ink levels. I'll
have to try that. Thanks!
Also, all 7 of our "North American" Pixmas can also print on printable
CD/DVDs, and all do an excellent job of it. Great printers...
