I did have a thread that was going to show the set up of a Ricoh with Sublinova, but the thread was deleted. If the thread hadn't been, and I had been able to finish it, there would have been photos showing how badly the Ricoh printed with Sublinova - the prints either had not enough ink in places, or were blotchy in others - not an effect I have seen printers do before. Banding wasn't an issue, but certainly ink flowing wrongly through the system was. That is where the experiment stopped really, I couldn't get it to print well enough to get to the stage of creating an ICC for Sublinova on Ricoh printers.
Maybe I had a dud printer, and others have been successful doing this, but I wasn't going to put any more time into it, especially as the thread detailing the experiment had already been deleted.
