What does printer error code CE.E5.66.0B mean?

[LosX]

Trying to help a friend set up their new 9125e HP printer. Can get it on wifi and can connect to it from phone and computer but it cannot read printer ink level and when I try to print I get the error CE.E5.66.0B

I suspect a HW issue where it cannot detect the printer cartridges. I tried to factory reset and re-do from scratch and it says I need to replace the cartridges (new printer cartridges came in box and dont expire until late 2026 hence why I suspect HW.

Can anyone confirm what CE.E5.66.0B might mean?

Thank you
