Lost admin password for HP Officejet Pro 8620

[Rainbow23]

Hi @WLeitner,

Welcome to HP Forums, this is a great place to get support, find answers and tips.

Thank you for posting your query, I'll be more than glad to help you.

I understand that you need to reset the password for your HP Officejet Pro 8620 printer.

You need to perform a semi-full reset on the printer to restore the printer to its factory settings and then connect it to the wireless network.

As the semi-full reset is a confidential information, I will be sending the steps in a private message. Please check your private message icon on the upper right corner of your HP Forums profile,

Next, to your profile name, you should see a little blue envelope, please click on it.

Please reply back on the public post to let us know if the issue has resolved or not.

You have a good day ahead.

I had to replace my hp 8620 printer and my old password won't work. I must have changed it, but I don't remember it. How can I find my password.

Thanks

I have the same problem.  I need to reset the admin password.

I would also like to reinstall the printer firmware.

Please let me know how to proceed.

I eventually found the solution here and it is surprisingly easy to do:

https://h30434.www3.hp.com/t5/Inkjet-Printing/How-to-do-a-full-factory-reset/td-p/6036673

1. Press back button 4 times until you see Support menu

2.  Scroll until you see Reset Menu (press right button in thr control panel)

3 Under the resets menu, you will find the  different types of resets, the partial reset, semi-full reset. Select the appropriate type of reset you need, and your Printer should start resetting itself.

The partial Reset

The partial reset basically just refreshes the Printer and clears out unneeded memory from the printer. This type of resets fixes minor printing issues such as slow printing, cartridge errors, etc..

The Semi-Full Reset

The Semi-Full Reset is the most useful type of reset. However, this clears out all the custom setting from your printer and returns if to its default factory settings. Use this reset if the partial reset does not fix your issue.

Full Reset

The full reset is the most powerful reset. If all other reset procedures is not working you can do this. However, it is not recommended as it really clears deep settings from your printer and any interruption on the reset process may render your printer unusable.

Please send me the "confidential" instructions to restore the printer to factory without having and Admin password. Suddenly our printer says the printer is locked by the administrator or person who set up the printer!! Which we DID NOT do!! This is maddening!!
