Likely causes and fixes

1. 1. The cartridge's electrical contacts are dirty or damaged, so the printer cannot read them.

3. 3. A used (non-new) cartridge was installed, or the wrong consumable was replaced (for example a drum unit instead of a toner cartridge), so the printer cannot recognize it as a valid replacement.

   1. Verify the correct consumable was replaced (toner cartridge, not drum unit).

4. 4. HP's Dynamic Security firmware authenticates the security chip on each cartridge and is designed to block cartridges with a non-HP or modified chip, including cartridges that previously worked before a firmware update.

   1. Check the printer's firmware update history in its settings menu.
