The Canon CRG-052H is a high-capacity black toner cartridge designed for efficient, high-volume printing. It provides a substantial page yield of approximately 9,200 pages, which means you can handle larger print jobs and go longer between replacements compared to standard cartridges. This cartridge is built for seamless integration with the imageCLASS LBP210 and MF420 series, including specific models such as the i-SENSYS LBP212dw, LBP214dw, LBP215x, and the MF421dw, MF426dw, MF428x, and MF429x. It is a practical choice for busy office environments where consistent text quality and reliability are essential for daily documentation.
