Wait image error and unresponsive Printer

[Djulzz]

Hello. I have an HP Laser MFP135wg bought 2 years ago.

When I turn on the printer, screen shows "System Initialise" and "Wait Image" after a few seconds.
I cannot connect to the printer using HP Smart on  Windows 10 or 11, printer looks totally offline. I tried connecting it via USB, same thing.
None of the buttons on the printer work, I cannot enter in any menu from it. It is totally unresponsive. I tried everything I found on your forums, nothing works (tried HP smart, HP Print and scan doctor, tried running a firmware update, etc....)

What should I do to make it work again ?? Please help, that makes me crazy for such a relatively new product !
 
Thanks.

Hi @Djulzz,

Welcome to the HP support community.

I am glad to assist you.

You might have to perform an NVRAM reset on the printer to fix this issue.

The reset instructions are specific for your printer and performing those steps on a different printer may brick the device.  

I am sending you a private message with the steps to reset the printer. Please check the mailbox icon at the top-right corner of this screen.

Hope this helps! Keep me posted for further assistance.
