This chip is compatible with all Hp printers that use cartridges series 920XL

When installing the chip does not detect the printer ink levels, indicating them with a question mark, but nonetheless continues to print. If the printer shows that "one of the cartridges is damaged or missing" means that the chip was positioned badly, so you have to shift it a little to find the right position

For a long and effective functioning of the chip simply: never update the printer in which they are used, be careful to voltage fluctuations and to avoid injury, do not wet them with water or other liquids and do not touch the chips by hand.

In case of failure of the chip for any reason, it is always possible to replace it with a new chip updated.
To replace the chips can use a soldering iron or a few drops of glue.
