then clearly I have no idea what I'm talking about...
I have to admit I'm quite suprised though, that such profiles exist
there at all.

So I think then what you are experiencing is similar to some other
recently reported problems.
I doubt it's a problem with your printer and it might not be worth the
ink use to do more of that sort of fix. I think they are looking into
some other over inking problems now, even on papers that they had
nailed in the past. There have been rumors of a change in the HPR
coatings causing a variety of problems.
I know others have contacted IJM about it and advise making your voice
heard there.

I've never heard of mechanical delivery being erratic in that way, but
I don't know, one learns over time that anything is possible. But I'd
go through the tech support route to see if it gets resolved there.
The more reports to them the better, and easier to diagnose.
