Hi,
Actually in the current setting the correct tray is chosen (2), so it asks for paper of that format to be inserted into that tray. Currently it works again, so it is really not following any logic anymore. No settings have been changed since, and the danger that it does not work again once more is great. So I really would need a way to disable this warning.
Maybe it is due to the fact, that the paper in question is borderline small, a little smaller than 110x230 mm in fact...
Cheers,
Roni
