LaserJet Printing

Hello

I need help resetting my printer to factory defaults,  After successfully setting up my printer, i went into the web app to set the administration password.  After setting the password, i could not use that very same password to access most of the administrative functions.  As well, i could not print via wireless after the password snafu.  So, i decided to reset the network settings.  As this printer does not have an LCD display, i followed the directions and pushed the wifi and cancel buttons together for three seconds.  I then began to add the printer via the IOS HP Smart App.  All went well until it asked me the question Enter printer password to continue setup. Well, that is why i had tried to reset the network in the first place.  I tried the only default password i had from the network summary sheet, WI-FI Direct Setup: 12345678.  That did not work.  I once again tried the password that got me into this mess in the first place; that did not work.  So, I tried again, this time holding the wifi and cancel buttons for five seconds.  Same result.  I then pushed just the wifi button until the power light started to blink,  Still, it asked me for a password.

So:

• Is there a default password that i just did not see in the documentation
• Is there a different means of clearing the network settings or non-volatile RAM
• Do i need to return the printer for a new one and try again
