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. High-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 MF620 series, LBP7110Cw, and MF8280Cw use Canon Genuine Toner, Cartridge 131 CMYK (CMY yields 1,500 sheets / K yields 1,400 sheets) and Cartridge 131 High-capacity Black (yields 2,400 sheets) ISO/IEC standard.
