Возможно нужна замена печатающих головок.

Firmware?

Do you have a Service Manual? There is a detailed sequence of actions.

"26:10 (possible candidates: ink cartridges, Prime Pump, Carriage Assembly, Trailing Cable)"

"27:10 ( Possible candidates: Printhead, Carriage Board, Trailing Cable.)"

"79:04 Generic printer error (FW assert)" - https://support.hp.com/us-en/document/c03051807

It happened quite recently, most likely this will help you: C1Q10A. Printhead replacement kit for HP 711 plotters.
Be sure to change as a set, i.e. when replacing PG, take cartridges from the kit
