Important Notice: This product is a toner cartridge chip. Before replacement, please ensure that the toner has been refilled to its rated capacity before installing the new chip. If the chip is replaced without refilling the toner to full capacity, the chip’s count reset may not take effect, resulting in the printer still indicating insufficient toner or displaying an incomplete toner level.
