I need to factory reset my HP Envy Photo 7800 series.

I foolishly lost my admin password that I created for my network printers control page/web server.

Hi @Limpingsnail,

Welcome to the HP Support Community

I understand you are facing an issue with your HP ENVY Photo 7855 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

We need to perform a Semi full reset to clear the admin password. The reset instructions are specific for your printer and performing those steps on a different printer may brick the device. 

I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer. 

In order to access your private messages, click the private message icon on the upper right corner of your HP Community profile, next to your profile Name or simply click on this link. 

Hope this helps! Keep me posted.
