Sounds like an interesting experiment. After all, Epson tried to
convince everyone that they had to use their inks and never stray or
change from dye to pigment or vice-a-versa also, and now there is a
huge industry in 3rd party inks, continuous inking systems, etc. So
maybe the truth is the Canons are no more critical, or not a lot more.
It seems the only way we'll find out is people willingly testing
their own printers and seeing what happens. One thing for sure, the
OEMs are in no rush to tell us anything ;-)

Who would beleive what I say?
Who would care?
I've realised when it comes to printers I'm a bit different to most
people here.
Anyway, I spent some time going through some journals, and other
material.
All I can say is theres a web of trademarks and patents breaking through
is not easy.
Eitherway, I did find enough out that the composition of the canon,
epson, hp, infact all digital inks, when being made to suit a printer,
all start from the identical base ink composition.
They then, through high speed photography, and trial and error, get the
composition of the ink correct so the ink reacts correctly, and is
normally left there.
They then get the inks colour and intensity correct, and then redo the
composition amounts to get it correct (as the amount of dye/pigment)
added changes it slightly.
The funny thing is if the inks wrong, it will dribble, have aliens
(multiple droplets instead of one) or the oppisite, not drip, and be left
hanging behind, or be too thick, and not fit through the nozzle, or
damage the peizo.
the actual percentage is minute, using the wrong ink has a high
possiblility of bad prints, a low chance of immediate failure.
If the print is effectively prefect (how do you know without looking as
the droplets fall?, anyway, that aside..) is all that matters when
getting the ink correct.
Also the Epson uses a flexible wall, Canon use a heating plate.
The bubble-jet has always had a short lifetime..
What I must ask is why can I put through literally 50k+ pages through a
short lifetime printhead (i560, running a CIS from new, did aprox 45k
pages and lost 1 black nozzle, currently still only 1 missing nozzle,
never been even looked at for maintenance, let alone head cleans). In my
opinion, for a cheap desktop printer, thats a VERY long lifetime.
Are the OEM inks designed to damage the printhead?
That sounds feasable, Treat the head badenough to let it last only a few
years of average use, forcing the people to upgrade?
Any other explanations?
I get heaps more pages through my printers without fault to most people
using oem cartridges.
Unless the 'sitting unused' is worse than printing pages????
I am gonna keep researching and experimenting till I come up with a
feasable thesis.
If you have any information in regards to any of this I'd love to hear
it.
