Officejet Pro 8620 needs full reset as I have forgotten username and password. How?

[RupertC]

I have just installed a new BT Hub Router and cannot access wireless setup as I have fogotten the username and  password. This prevents me from getting past the comtrol panel lock. I have tried disconnecting the power and reonnecting whilst holding in the on button but this seems to do nothing! I have now deleted the printer in system preferences but this still doesn't let me reinstall without the username and password. Please help as now a good printer is useless!

Hi @RupertC,

Good Day. Thank you for taking an interest in the HP community. I understand that you require assistance regarding issues with connecting the printer to the Wi-Fi network after changing routers. I will be really glad to assist you here. 🙂

Fabulous description and superb diagnosis of the issue before posting. Kudos to you for that. )

For better clarity and to assist you better I would require more information regarding this:

• Did you try to restore the network defaults of the printer to factory settings?

For now please try these steps:

• Please perform a network defaults restore on the printer and it will reset the printer to factory settings from this user guide link: http://hp.care/2t7Na9C and refer page#39 on how to do it.
• Then try to connect the printer to the wireless network using this document: http://hp.care/2vWEIvW
• This should do the trick for you.
• If this does not work, I will send a private message on how to perform a semi full reset to factory settings in a private message. Please keep checking your forum private messages.

Please perform all these steps patiently as it is critical to resolving the issue. The trick is to remain patient, please.

Hope this helps. Let me know how this goes. I genuinely hope the issue gets resolved without hassles and the unit works great.

Then add the printer to the network by following these steps:

1.) Click the Apple menu icon, and then click System Preferences.

2.) Click Printers and Scanners, Print and Scan, or Print and Fax.

3.) In the Printers list, click your HP printer, and then click the Minus button to delete it.

4.) Click the Add button.

 5.) Find, and then select the name of your printer from the Printer list, and then click Add to add your printer. Do not select an HP Fax driver.

6.) Click the Use or Print Using box, and then select the name of your printer.

7.) Avoid the AirPrint driver. Once the correct HP driver is chosen, select Add to add the printer to the list.

8.) Try to print.
