ET-8550 - Repeated ink filling over 2/3 of the ink tank could damage the printer.

I saw this mentioned on DPReview (where I don't participate) and thought huh?
So I checked and there it is:

The only thing I can think it might be talking about is that inserting the bottle always releases a little ink and doing that repeatedly could fill the tank past the normal automatic cut off level.

That's for a different printer. I looked at the ET-8500 manual and didn't find anything like that. The only thing is that they mentioned that for optimum results it's good to top it up to 100% at least once per year.

On my ET8550 with the newest firmare OP28P8 ,i have the same information(in German), when the Ink tank cover is opend.
From my understanding, you have to wait when your ink level drops under the 2/3´s ,to fill it up(with full bottle of ink)
I think it has to do with the hydrostatic-pressure which could be to high for the dampers to fill it poperly ,or the Valve in the bottle can only close fast enough ,when some amount of ink is out of the bottle.
