HP Officejet 4500 G510n-z all-in-one series, Power button

[Tonyey20]

HP Officejet 4500 G510n-z all-in-one series wireless.

When I press and release the power button, it does not start and no lights appear.

If I press and hold the power button down for about one minute, the printer lights up and functions just fine.

To shut the printer down I need to hold the power button down for about a minute.

Hi @Tonyey20,

Welcome to the HP Support Forums! I see the power button on your HP Officejet 4500 is non responsive, if you press and hold the button for a minute the printer will light up and function as normal.

I would like you to start troubleshooting here: The HP Printer Won't Turn On or Respond When the Power Button is Pressed

Please let me know the outcome. I will watch for your reply.

Thanks,

Thank you very much.  I needed to reset the power supply and I neglected to understand how to do this.  It appears to work fine now.

I thought the problem was solved, but the button must be held in for a long time for the printer to start.  I purchased another power supply (a used but tested one) but that did not help.

I am having the same problem. The copier scan light glows when the power is on, but the printer otherwise appears dead, and the front panel is completely unresponsive.

Furthermore, the hold-the-start-button-down-for-a-minute trick does NOT work.

Any suggestions out there?

Thanks,

Brice

I tryed all things in the document but none solved the problem.  So, I assume it is the printer.  Once I get the printer started, I never turn it off.  It goes to sleep after a while but wakes when I need it.  That solves the problem for now.  Thank you for the help.
