@CN8993G3D9 Could you send a picture of the error message, so we know exactly what we are dealing with?

Also, in the meantime, try the below steps:

Check if the copier is working, if it's working fine:

• 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.
  • NOTE: 
  • 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.

And upgrade the printer firmware using the steps mentioned here.
