Well, mine clearly can get filled as much as you dare to ;-)

I'd dread to make a hole in the bottom (where gravity will not be your
friend), also, that would make it impossible to fill inside the printer.

OK, i can see how that happens - the ink levels will equalize due to
gravity.
The vent hole is the same size as the fill hole, but i didn't get any
spare stoppers with it..
Maybe i'll make one from silicone... OTOH i might just remember the
warning and wash it out when the problem turns up, or stick in a syringe
since the hole fits a luer taper.
Thanks!
BTW, the carts came with some strange syringes. Huge diameter and the
plunger is hollow inside, so that there's always much air inside it that
can not be expelled. Any ideas how those are supposed to be especially
useful?
