The Canon CRG-055 is a yellow laser toner cartridge designed for users who need reliable color printing in their office or home workspace. This all-in-one system integrates both the toner and the drum into a single unit, which simplifies the replacement process since you don't have to manage separate components. Engineered for efficiency, it offers a page yield of approximately 2,100 pages based on ISO/IEC 19798 standards, making it suitable for those with moderate printing volumes. It is fully compatible with the Canon i-SENSYS LBP660C and MF740C series, including specific models such as the MF744Cdw, MF742Cdw, LBP663Cdw, and LBP664Cx, among others in the MF741 through MF746 range.
