Don't know what the odds were, but I do know that an associate of mine at work
must have had a set of these [or clone] chips in a set of carts he bought for
his r200 at a 'week-end computer show'. They were even advertised as 'easy
refill', and sold with spare ink. He killed the printer within 90 days [so he
just took it back to Sams]. After observing it, we saw that it was OK if you
powered it down with the top button, but if you removed and re-applied line
power [even with the lights off and the printer apparently powered down], it
would do a clean cycle. I suppose a bug in the way they implemented the
auto-reset [and perhaps the reason for the reference to 'less head damage' with
the new design].
As to 'ending up' in single use carts -- the chip seller [according to his own
web page] even sells them for that purpose [why, I don't know].
Remember my original 'bull' reply was in response to the flat out statement that
3rd party carts could not possibly have anything to do with the problem -- which
is simply not true. Sure, if you buy on trusted recommendation, or buy from a
source that you know for a fact hasn't just changed supplier, you will probably
be ok -- but regardless, you are the one doing the QA with little recourse
[depending on the vendor] if you have problems.
[And yes, my r300, chugging away on overpriced oem ink, is still going. To me,
it's worth the price to not have do someone else's QA on my hardware with every
new cart I buy.]
