HP reports a problem with one or more cartridges — missing, damaged, counterfeit, or incompatible. Reseating, cleaning contacts, and matching firmware usually clears it.
Work through these in order; most people are fixed by the first two or three.
Remove each cartridge, peel any tape off the contacts, and reinstall firmly until it clicks.
Wipe the copper contacts on the cartridge and inside the carriage with a dry, lint-free cloth.
Install cartridges one at a time to find the unit triggering the error.
If a firmware update started rejecting third-party ink, fit a genuine HP cartridge to confirm the slot works, or use cartridges made for the current firmware.
