The MyCartridge.md CRG 072H is a black laser toner cartridge designed for high-volume printing on Canon imageCLASS and i-SENSYS devices. This high-yield version allows you to print up to 4,100 pages, making it a practical choice for home offices or small businesses that need to handle a steady stream of documents without frequent replacements. It is compatible with the LBP172 and LBP172dw series, as well as the MF284, MF287, and MF289 models, including the MF287dw. Please note that this specific model is supplied without a chip, which means it is intended for users who are comfortable transferring the chip from their original cartridge to ensure the printer recognizes the new toner.
