This new addition to our most popular product line is also downward compatible to the older Ricoh 1060 series machines. This provides a reduction of inventory carrying costs for you as one cartridge handles the MP 5500, 6000, 6500, 7000, 7500 plus the older 6110d machines. As with all of our Aficio products, they are also compatible with Lanier, Gestetner and Savin equivalent machines.
