@Julesfoxy Lets start with power reset as per HP standards, here's how we recommend doing it:
Turn the printer on, if it is not already on.
Wait until the printer is idle and silent before you continue.
With the printer turned on, disconnect the power cord from the rear of the printer.
Unplug the power cord from the wall outlet.
Wait at least 60 seconds.
Plug the power cord back into the wall outlet.
HP recommends connecting the printer power cord directly to the wall outlet.
Reconnect the power cord to the rear of the printer.
Turn on the printer, if it does not automatically turn on.
Wait until the printer is idle and silent before you proceed.
If the issue persists, please upgrade the printer firmware:
