Very interesting Sabin.

My question on reading this is whether there is a bigger price to pay down the road for turning off as much of this maintenance stuff as possible. I suppose we won't get to know that unless or till something unwanted happens. Or put another way, there has to be some logic behind the default settings and some logic behind the options to tune them way down, but none of that logic is anywhere explained, so we are a bit in the dark on all this, taking the long-term perspective on it.

Thats a good question. Time will tell I guess.

I read somewhere that the dryer the air, the more the chance to get clogged nozzles. I guess that hot and dry is the worst scenario. If one get clogs from time to time, it's better not to disable the extra maintenances. In my case with only one case of very faint clogged nozzles I have decided to risk it. No because it's too expensive, but because I'm curious what will happen. BTW today searching for something in the canon documentation I found a text in the printers manual regarding ink maintenance. It states that some ink is used to clear air bubbles from the system. So in theory the negative may not be only clogged nozzles, but decreased printing quality as in fact Canon warns in the manual about disabling this functions.

That Ink Maintenance is only about letting the printer agitate the cartridges periodically. It isn't about cleaning cycles.

It must be about something else because I set mine to off and it stills agitates the cartridges.

Strange, because I consulted the manual (at least the version I have) and what I reported is what it appears to say about that setting. I use the world "appears" because the use of the English language and editorial structure in that manual leaves a lot to be desired, but I thought this was reasonably understandable, so I mentioned it.

I confirm that, mine also with IM off agitates the inks.

You are right about what the manual states. I checked it and it's clear. But I just printed two and it agitated the inks as usual despite the "Ink Maintenance" is set to "OFF". So what the manual states is at least strange not to say inaccurate :).

Not the first time. Perhaps useful in the final analysis to ask Canon directly what they mean by this, because in light of reported experience it may well be less clear than it seems!

I have the same behavior with my Pro 1000 as well and I think this is an essential feature to prevent the pigment particles from settling, thus affecting the output quality or even worse clogging the printhead if an excessive amount is passed through the nozzles. This is MUCH better than having the remove the 12 cartridges manually and shaking the tanks. Epson users can only dream of the features and technology found in the Pro 1000 :)
