Are you using original HP ink cartridges or refilled ink? If it is original HP ink then the evidence points towards the printhead failure.
However, I recommend you to perform the following steps to isolate the issue and arrive at a fix:
NOTE: Please skip any steps that you might have performed already.
Disconnect the power cable from the printer while the printer is still ON.
Disconnect any other cables if connected the printer.
Press and hold the printer's power button for 15 seconds.
The printer should be directly connected to the wall outlet and not to a surge protector.
Reconnect the power cable to print and the printer should power ON by itself. If the printer doesn't power ON then please manually power it ON.
If the error persists then please perform a firmware update on the printer via this link.Please restart the printer once after the firmware update.
If the issue persists then I suggest to reset the printer. Resetting the printer restores the printer to its original factory settings. I have sent you a private message with the steps to reset the printer.
