Hello Mark,
Everything is fine down here if we ignore the politics... well, I think that is true almost everywhere!
My Z3200 is temporary out of order due to star wheel assembly stuck on the upper position. I am waiting for a calm day to open it and see what happened. I use it mostly for BW prints and profile creation this days.
You are probably right about the paper size, I never tried anything smaller than a 17" roll for head alignment.
Regards.
