Users of this supply who upgrade to the latest HP firmware may experience issues with cartridge recognition.
Please note the following:
- Firmware updates for these printers are prompted when a Wi-Fi connection is enabled.
- Cartridges ALREADY INSTALLED will continue to work even if the update is accepted.
- Once the firmware update has been accepted the printer will continue to function normally until a cartridge is replaced. On replacement, the cartridge will not be recognized and the printer will not function.
- This issue is industry-wide and GSS is actively working to update chips accordingly
