HP Color LaserJet Pro MFP 3301fdw Setup/Troubleshooting Menu Locked

[kcarver]

I have an HP Color LaserJet Pro MFP 3301fdw.  It has been a bit squirrely.  The most recent issue is that the Settings / Troubleshooting menu (in the control panel) locked itself -- the padlock icon suddenly appeared.    I didn't lock this.  It asked for a username/password to unlock.  I have not set any passwords or any users nor locked anything.  The only thing that has changed with the printer since I received it a few days ago is that the firmware was updated.  If anyone has some insight as to how this occurred and how to unlock, I would appreciate it.

Hi @kcarver,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand the firmware update might have changed some settings or added default security measures that weren't present before. 

Here's how you might resolve the issue:
 

Check Default Credentials: Sometimes, firmware updates set default credentials. Try the following:

• Username: admin
• Password: admin or 1234 or leave it blank

Reset to Factory Settings: If default credentials don’t work, you might need to reset the printer to its factory settings. Note that this will remove all custom settings:

• Navigate to the Setup menu on the control panel.
• Find the Service or Maintenance option.
• Look for a Restore Defaults or Factory Reset option.

Access via Web Interface: You can also try accessing the printer’s settings via its web interface:

• Ensure the printer is connected to the same network as your computer.
• Open a web browser and enter the printer's IP address (you can find this on the printer’s control panel).
• Log in using default credentials or any previously set admin credentials.

Firmware Update Reversion: If the issue started after a recent firmware update, consider reverting to the previous firmware version if possible. Update the firmware on an HP printer
