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 LBP712Cdn uses Canon Genuine Toner, Cartridge 040 CMYK (Black yields 6,300 pages, CMY yields 5,400 pages) and Cartridge 040 High Capacity CMYK (Black yields 12,500 pages, CMY yields 10,000 pages), ISO/IEC standard.
