HP firmware blocks cartridges: the truth and how to avoid it
UpdatedShare

Menus differ by model, and some HP services require automatic updates. Consult the official guide for your printer before changing its settings.
If HP does not offer an earlier version for your model, do not install third-party firmware or firmware for another printer. Check official support, send the seller your cartridge details and compare options using documented compatibility and current costs.

Using a non HP cartridge does not automatically void the limited warranty of an HP printer. HP indicates it may exclude coverage for damage attributable to the consumable used, but the mere presence of a compatible cartridge is not enough to explain a breakdown.

Before contacting HP about a complaint
Describe only what you can document: model and serial number, purchase date, cartridge reference, previous and current firmware if known, displayed message and date of failure.
