If your ink cartridges suddenly stop working after initially working well, it may be due to a firmware update from the printer manufacturer. These updates occur automatically if your printer is connected to Wi-Fi or directly to your computer with an internet connection. The default printer setting is usually to allow these updates without requesting permission.

Since 2016, HP's firmware updates include dynamic security to limit the use of these cartridges. Dynamic security-enabled printers only work with cartridges that have brand-new or repurposed HP chips.

This firmware feature blocks cartridges with non-HP or modified chips, preventing the use of remanufactured or third-party ink cartridges.
