Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Try these steps -

• 1) Turn on the printer, if it is not already on. 
• 2) Wait until the printer is idle and silent.
• 3) With the printer turned on, unplug the power cord from the printer & wall. 
• 3) Wait for 60 seconds.  
• 4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not into a surge protector. 
• 5) Turn on the printer, if it does not automatically turn on.

Also, try updating the printer's firmware. You may also refer to this document - HP Printers - Updating or Upgrading Printer Firmware
 

Step 2 Reboot the devices - 

• 1) Turn off the Router, Printer, and computer.  
• 2) Wait for 60 seconds.  
• 3) Turn on the Router first and wait for all the lights to stabilize.  
• 4) Turn on the printer and allow it to configure itself.  
• 5) Turn on the computer. 

Hope this helps! Keep me posted for further assistance.
