If what they say is correct then Canon are deliberately slowing down the
printer when the printer detects a refilled cartridge since the cartrdige
itself cannot slow down the printer.
If that is indeed the case then this is, in my opinion, a questionable practice.

My take on this was that the slowdown, if any, was due to having bypassed
the low ink warning system, which is required if re-filling or using
compatibles. More of an indirect thing than deliberate.

But it would be a pretty easy thing to check out and verify. Nobody has yet
reported any real issues because of it, or any slow-downs for that matter.

I also have not seen any reports that support the claim that the printer slows
down, and the printers in this range that we see on a weekly basis seem to
print at full speed whether the owner has new OEM cartridges or refills
installed. So until I see some evidence that this claim (by alotofthings) is in
fact valid I guess I won't worry too much.

Anyone who might be concerned about slow throughput would not use the
automatic duplexing mode of the Canon printers (ip4000, 4200, 5000, etc.)
While it is a very clever "paper shuffle" to turn the paper over and print
the second page, it is extremely slow.

The link is from alotofthings, not Canon, but they claim to be quoting Canon tech service:

It slows down because it feels like throwing up
