HP LaserJet MFP M29w: Need administrative password to EWS webpage and HP Smart APP

[shockwaveriderz]

I've forgotten my username/password for this printer and I can't get into the EWS webpage or hp SMART to change items. I had to remove then reinstall the printer in win 10 20H2.  And now I can't access the settings. How do I reset this printer to accept new username and password? Or will a simple factory reset work? If so how do I perform that.?

Now the printer won't even work and print a test page. I get the Hp Diagnose and Fix   loop to print a test page and get a Default, Attention required message in win 10 and the Yellow warning light icon on the printer starts blinking until I power cycle the printer. 

Ok I completely removed the software and restarted the PC.  I re-installed the software complete and I still get the same error.

the printer blinks green and yellow on boot up , then goes solid green and the blue icon starts to blink finally stopping. Whenever I try to print a test page  it say 1 document in queue then the triangle yellow light goes on and I get the message Default, Attention Required. 

Please provide instructions on the steps to take out ALL of the installed software . I have taken the printer toner cartridge about 3 times now and put back in and doesn't help.
