Can't access EWS after firmware update. Invalid login credentials error

[m0429]

After a recent firmware update to my HP DeskJet Ink Advantage Ultra 4729 All-in-One, I can no longer access the EWS on the printer. It was connected wirelessly and login credentials were default. But after the update I can't login anymore. I'm getting an invalid password error everytime. I've tried resetting the printer but that made it worse. Now I can't connect the printer to a wireless network without logging into the ews anymore. Doing it through the app on my windows machine throws up an invalid ssid error to whatever network i try to connect to. I couldn't find any workable solution to reset the ews panel password. Please help

@m0429 Greetings from the HP Community!

here's what I suggest you do:

Open the EWS and reset the password

1. Open a web browser and type the printer IP address in the address field exactly as it appears on the Configuration Page,  and then press Enter.

2. Click the Security tab, and under General Security, set the local administrator password.

   1. Keep the username default as admin.

   2. Type the New Password and Verify Password.

   3. Navigate to the bottom of the page and click Apply.

Use these credentials the next time you Log In to the EWS.

If the issue persists, try the below steps:

The printer cannot be connected to a network. Use these steps to reset the printer settings to re-establish a network connection.

I have already done this. But it still asks for password when i open ews. Default username and password don't work either. I think it's not resetting the ews on my printer.

The printer isn't connecting to a network either. I can only open ews via wifi wirect.

I've tried reconfiguring wireless option with usb connection. But I'm not being able to connect it to the network. It's showing ssid unavailable even through they show up while scanning. It's happening with any ssid i try to connect to.

I tried contacting the number you provided but they refused to help and told me to bring the printer to a service point. The nearest one is a bit far from me which I also told them. The issue seems to be a technical one. Don't get why it can't be fixed over here to be honest.

So almost everyone suggested I take it to a service center. Today I took it to the nearest one which is still far away from where I am. After struggling with the printer for about half an hour they said They can't figure out what the problem is with the ews and said I need to change "the motherboard of the printer" to fix the issue. They couldn't explain why it needed the hardware replacement other than it'll 'probably' fix the issue. Since my printer recently went out of warranty it'll cost me about half the value for which I purchased it. So if anyone in here can help me with the ews password reset I'll be very glad. Otherwise it'll basically become a piece of junk from a perfectly working machine

Hello, 

Kindly try the below steps ....

Step 1 - starting from printer off, quickly press and release Power button.

Step 2 - power up till steady white light.

Step 3 - holding down Power , press and release black “ Start Copy” button.

Step 4 - then press and release red “Cancel” button 3 times.(Note: one must NOT have released the Power button yet).

Final Step - now release Power button and wait for steady white light again..

Now access the Printer EWS using Wireless Direct, and initiate Wireless Setup of the printer.
