Menu access is disabled on LaserJet Pro MFP M148dw

Hi there,

I  bought LaserJet Pro MFP M148dw yesterday, and started configuring it today. I set up the https and firewall successfully.

Then I set the administrator password. Now I am logged out from the browser UI and the password I entered, is not accepted in the login (Yes - it is the same I gave when I set it).

How do I do factory reset?

Thanks,
