The cartridge is filled with 1-component insulating magnetic toner (if iR3570/4570, 1220 g; ifiR2270/2870, 1060 g). When the sub hopper requests a supply of toner, the cartridge itself rotates to feed toner. The machine's toner cartridge serves as a hopper(as it is found in past models).iR3570 / iR4570F-7-14iR2270 / iR2870F-7-15Points to Note on Handing the Toner Cartridge1.
