For inkjet printers, two components require chip reset: the ink cartridge and the maintainer. Align the chip with the corresponding groove so the probe contacts the chip on the ink cartridge, ensuring both components are securely attached. If the red light illuminates, the connection is good. After approximately 5 seconds, the red light turns green, indicating the cartridge chip data has been successfully refreshed. The ink cartridge can be used after refilling with new ink or compatible ink. Color: Blue Material: ABS Package Contents: 1 x Cartridge Decoder Note: The above package includes only the items listed.
