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

Remote troubleshooting (call agent) 1. This error never appears in the Front Panel, it is only logged into the Error History and it is equivalent to the message: There is a problem with the printer or ink system. Turn printer off, then on. If the problem persists, contact HP. 2. See Ink system hardware troubleshooting.

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
