Compatible Cartridges and Firmware Updates: Why Recognition Can Change
Why compatible cartridges sometimes stop being recognized after firmware or software updates.
Quick answer
Compatible cartridge recognition can change after firmware updates because printers, chips, and supply authentication all interact. Keep return windows and avoid bypass promises.

Why it happens
Printers may change how they identify supplies. A cartridge that worked before can become unreliable if firmware behavior changes.
Practical protection
Buy from sellers with clear compatibility and returns, keep one known-good supply if printing is mission-critical, and avoid counterfeit packaging.
