You will receive the HP Printer Validation Failed message on your computer when using HP ePrint apps.
A portion of the regular purposes behind the mistake are:
Imperfections in the printer
Befuddled printer driver
Carriage isn't working
Blunder in the product update
A straightforward restart can assist you with investigating the mistake.

If the printer will startup with no cables connected but 49's when you plug in the network cable then a computer on the network likely has a corrupt job in it's print queue that is causing the 49 error to occur. Your best option is to connect the printer to a workstation or laptop with a USB cable and update the firmware that way if you cannot find the workstation that is causing the problem. Keep in mind that the 49 error might occur after update if that corrupt print job continues to be sent.
