I can't find the guide.

Hi @Printer828,

Welcome to the HP Support Community

I understand you are facing an issue with your HP Smart Tank 790 All-in-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• Could you please share a picture of your printer?
• HP Smart tank 790 has buttons.
• Are you facing any error message on the printer?
• Why would you like to perform a factory reset the printer?

While you respond to that, While you respond to that, Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle
