They all operate in the same way.Align the chip with the corresponding groove, so that the probe corresponds to the contact of the chip on the ink cartridge, and the two components are closely attached. If the red light is on, it means the contact is correct and good.After about 5 seconds, the red light turns to green light, which means that the cartridge chip record has been refreshed.The ink cartridge can be used when it is filled with new dye ink or other brand/compatible ink.Colour: blueMaterial: ABSPackage Contents:1 * Cartridge decoderOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
