Pull out the developer unit, cheat the front interlocks , run forced toner supply and look in the back where the developer unit would connect at the back of the machine. There are 2 motor couplings that should turn. If the hopper is full and there is no toner in the developer unit then I think it would be the top coupling for the toner hopper toner feed paddle. D059 3261 Pump: Toner Supply: Ass'y. Hope that helps

I had the motor that drives the dispenser in the hopper go bad. Also check that the dispensing holes on the bottom of the hopper are not clogged.

I had an e Studio 905 (rebadged Ricoh 907) undertoning and giving SC495 codes. It turned out to be the toner pump. Over 600 copies it transitioned from a good copy to completely blank. =^..^=
