Ricoh duplicator : "Auto-printer 1510" manual or any information ?

[Kevin Donnot]

Hello,

I bought a mint "Ricoh Auto-printer 1510" offset duplicator. I am looking for any document regarding this material (user manual, repair manual, datasheets, using documents...)

Internet does not provide any information about this press. Just few pics of the "1010" model that seems to be close... Do you know anything about it ?

Thank you for your further answer,

Kevin Donnot
