Re: Ricoh mp6503, copies with dark background

I had this same problem recently and it was a fault caused by the toner and that was original. It would be a defective batch I imagine . I had to empty the toner hopper and change developer and run a sp2963 to initialize the developer and fill the hopper with another original toner from a different supplier and it worked. You have to enter service mode with the door open as previously tonerhead mentioned. Then I returned the defective toner, of course.

Exactly what I was suspecting. Its does sound like defective toner

Come to think of it, we had same thing. Not sure if it was the case, but we sent some oem toner back as dictated by manufacturer as defective.
