As in the office per month, a toner is needed I bought from these same 10 items at a time. For quality, I can only say that the original remains original. I've tried Rebuilttoner, but you had to make huge compromises in quality matters, so I am back to original toners and changed since then determines the print quality. Even the specified page number comes out mostly I get even more pages out if you shook out the toner towards the end again.
I can only recommend everyone to rely on original accessories of the printer manufacturer.
