Michael,
Out of deference for your opinion, I will apologize for having used language that could be interpreted as insulting, and above all became a pretense for distraction from the substance of my original post. I will submit as attenuating circumstances though, that as one of the few people whose business is indeed jeopardized by the premature failure of my 9900, which has a near 100% probability of being imputable to a defect in manufacturing or engineering, it becomes really aggravating to read some posts which are consistently, and beyond reason, advocating in the defense of the manufacturer in a way that is very insensitive to our pain.
So now, please bear my re posting some of my comments that this incident has distracted us from:
Personally I was not born with a prejudice for or against Epson, I just wish they would take responsibility for what is clearly a manufacturing of engineering defect, under warranty or out of warranty, period. It is ludicrous to contemplate LLK drying inside the head, clogging and the like. LLK is one of the most fluid inks in the lineup, one that hardly ever clogs (regular clogging) and it does not dry solid at air contact. If by extraordinary it could have "solidified" my testing demonstrates that it would have been dissolved by the cleaners that I have put in the channel, and instead, while there was no ink left to create clogging, the head kept "clogging." The only logical conclusion is that there is no clogging going on in this case. On another hand most head failures on x900 are extra overwhelmingly on the LLK channel, and anybody with logic and a reasonable understanding would start to assume that the likelihood of an engineering or manufacturing issue here is then quite high, and certainly the first presumption.
The extended warranty is a solution for volume printers. For others, it prices Epson well outside of the affordability range, let alone that the alternatives (Canon, HP) are already roughly 50% less costly before the extended warranty.
Epson should bite the bullet. I have very (let me retype VERY) good reasons to suspect that they don't know how to technically resolve the problem, prevent those premature head failures to occur. But since the users are not responsible for that, and since we are talking of a relatively small numbers of users, it would be feasible and the honorable thing to do, to rescue that relatively small amount of people, just like they did with James Haswell (page 25), and emerge ahead in terms of image.
Don't you think?
