Like other cartridges in this series, the board for these cartridges has two contact pads where the machine makes direct contact. New replacement chips are available now. On the Non- Prebate cartridges the chip is also present, but the killer part is not active. These cartridges can be re- manufactured as much as you want, the chip will not interfere. There are multiple other printer brands that use this engine. Make sure your replacement chip is universal or brand specific if using in these machines.
