Designed by Canon engineers and manufactured in Canon facilities GENUINE supplies are developed using precise specifications so you can be confident that your Canon device will produce high quality results consistently. Hi-Capacity toner options keep up with your busy printing needs so you have less replacement efforts and more time. The Single-Cartridge System combines the toner and drum into the same unit which means you only have one consumable to replace. The LBP312dn uses Canon GENUINE Toner Cartridge 041 Black (yields 10000 sheets ISO/IEC standard) and Cartridge 041 Hi Capacity Black (yields 20000 sheets ISO/IEC standard).
