HP LaserJet MFP M234sdw - factory reset

[haardath]

Hi, 
The admin password was set up for the printer but was unfortunately missing. 
We tried resetting wireless network settings as was advised here in the forum - but it didn't help. 
We tried other ways suggested in the forum, like holding the resume button during the start - it doesn't work, and nothing happens. 

In the user guide, there is no information about hard reset. 
Could you please provide some instructions for that? 

Thank you.

Hi @haardath,

Welcome to the HP Support Community. 

I'd be happy to help you! 

Try the following. 

Unplug the printer, then keep pressing the "- Button" and the "X button" at the same time, then plug again the printer and if everything is ok, in the display, should appear "NU" or "NV"

This procedure is for a factory reset, not only a network.

Turn the product on while you press and hold the Resume button for 10-20 seconds. The Attention light turns on. Release the Resume button. The Attention and Ready lights cycle while the product restores factory defaults.

 If the information I've provided was helpful, give us some reinforcement by clicking the Accepted Solution button, that'll help us and others see that we've got the answers!

Thanks, we tried that, but nothing happens when we press buttons while turning on. No  NU or NV appeared on the screen.  It's just normally started and then connected to wifi.
