I called them right now. They're going to send me a replacement. I'm
surprised, because the warranty has expired by a couple of weeks.

But, as has been pointed out, some things should last longer than
guarantee time, such as cookers, televisions and three piece suites.
Your problem appears to be with the operating system of the printer
which are not replaceable by you and should last longer than the
consumable parts.

12 times is AP position error [6A00] never ending blinking is a rom
problem.
So it's complaining about either the sheet feeder or the logic board,
or a wire connection between the two units. I imagine sucking up
something into it would also result in this condition.

But canon shipped a replacement... cool. And given the nature of the
error it should be a new one, with new ink, and a new head. Bonus. I
wish mine would screwup that badly, but unfortunatly it's just too damn
reliable.
