Hello!

I need an instruction to do Full Factory reset for HP LaserJet Pro MFP M28w.

I see multiple topics on this forum, but answers are providing via personal messages, so I've had to ask for a one.

Thanks in advance!

Hi @pgkmot 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for reaching out—I'm happy to help with your HP LaserJet Pro MFP M28w. A full factory reset is a powerful step that restores all printer settings to default, including network configurations, preferences, and stored data. 

But before we proceed, I’d love to understand why you’re considering a reset.

• Are you facing connectivity issues, print failures, or configuration problems?
• Did the printer recently stop responding, or are you trying to clear old settings before handing it off or reinstalling?

Many issues—like Wi-Fi problems, stuck print jobs, or driver conflicts—can often be resolved without a full reset, and I’d be glad to guide you through those if needed.

If you're resetting due to a specific issue—like trouble connecting to Wi-Fi, printing errors, or supply system faults—let me know. I can offer targeted troubleshooting that might save you time and preserve your settings. 

You're doing everything right by asking first.

We're looking forward to helping you get back up and running! 

Regards,

When I try to add a printer via HP Smart Windows app, it keeps asking me for the device password, which is unknown to me. Please, don't suggest me using a mobile app, and just send me a manual for factory reset. Thank you!

Sure, I'd be happy to assist you further.

These steps are specific to the printer and I am afraid trying on a different printer might brick it.
