RA 5900 which drums do fit.

[Jonesi]

Hi,

I'm pretty new to riso printing.
We have only one drum, but we want print multiple colors.
So I'd be really happy to know what kind of drums do fit in my Risograph RA 5900.

Thank you guys!

That machine was launched in 1993, nearly 30 years ago. There is nothing in current production that is anywhere close to it. Try looking on Ebay. Good luck.
