Ricoh Afico CL7100

Hi.

First Post so please be gentle

I have a ricoh aficio CL7100 and it is printing with 3 very small smuges of black toner on the print out's both single sided and when duplexing. On top of this there is a very slight trace of fusier oil on the edge of the paper either when single sided or duplex.

I would image I need to clean something - but what?

Thanks very much for your help.

Chris
