Digital BW, The Print

This is obviously a point of concern for those who may be thinking of the 
dual printhead approach for Canon printers (I'm one, though probably with 
Lyson Small Gamut inks when they become available in bulk for the Canon 
9000) but I'm curious as to the source of the trouble reports.  It was my 
impression that Canon has only been selling the printhead separately for a 
month or two.  Has someone found the problems you describe in just that 
short period?

I've removed my (only) printhead several times in the 8 months I've had the 
printer, to rinse it out under a faucet in an effort to clear persistent 
clogs.  I never had a problem with banding or alignment after it was 
returned to the printer carriage and put through several cleaning cycles to 
refill the heads with ink.  Is there some concern that the printheads 
available as "spares" from Canon somehow don't meet the same specs as 
"original equipment" and so somehow mess up the printer mechanism?  I'm 
having a hard time imagining how this would happen, mechanically.

Any details would be appreciated.  I'm hoping to stick with the Canon and 
dual printheads for B&W and color printing, largely for its much faster 
printing times compared to the Epsons.  But if for some reason the two 
heads approach doesn't really work reliably, I'll have to rethink my strategy.

Cheers,
Kip
