C6000: Can it print on transparency / clear film?

[oxident]

Hi!

Does anyone know if the KM Bizhub C6000 can handle transparency (clear film) media? I've already tried using "Plain Paper 105gsm" and it somehow works ... but there are tiny, colorless "spots" all over the sheets.
I guess it has something to do with the temperature / process settings...

Thanks for any help!
