Digital BW, The Print

One issue I have not seen addressed with the new Cone system is regarding
longevity issues due to the inherently different design of the Canon print
heads. My understanding is that Canon (and most if not all non-Epson
inkjets) are not making their print heads replaceable out of the goodness of
their hearts, but because they have to--the tiny electrical "heaters" that
force the ink out of their heads have a relatively limited life span...or at
least less than the expected life of the printer. (I am paraphrasing, but
Epson claims that their system based on the electrical deformation of a
crystal to squeeze out (variable) ink droplets will last the life of the
printer...so making their print heads non-replaceable by average Joes like
us is actually a FEATURE. Ha ha.)

In any case, does anyone have further info on exactly how long a Canon print
head can be expected to last with pro-level use?
