Reset Administrator password on HP Color LaserJet Flow MFP M577

Hi all, I need assistance on how to reset Admin password on a HP Color LaserJet Flow MFP M577. I think the previous guy(Admin) changed the admin password and now I cannot log in via browser or printer. Your assistance would be much appreciated, thanks.

You need to access the preboot menu of the machine and perform a cold reset under administration menu and startup options. If that does not work there is a partial clean option but that will clear any scan to folder and other settings, but if you backup first you can restore as long as you do not change the firmware revision between when you make the backup and when you restore. Preboot is accessed by turning off the printer, turning on and touching the HP logo on the screen immediately when the black line appears under it

Thanks, I did the reset, updated the firmware and manage to reset the admin password.
Thanks again
