have an HP Envy 4520 which the scan refuses to work

[BobM10]

I can print to my printer/scanner with the USB connection using HP Smart.

When I use the HP Smart App to scan it creates everything as an HTML doc. I want it saved as a PDF or GIF. The HP doc states go into preview and change the type. There is no "type" option visible from the preview permitting you to change it to say a PDF.

When I enter scan then pdf from the printer/scanner it states that it can't find the connection, despite the USB working fine when I print from HP Smart.

I have uninstalled and re-installed HP123 3 times to no luck. I am about to do the next step. Take the printer outside smash it with a sledge hammer and buy a new printer/scanner - anything but an HP. Any help before I destroy this printer/scanner?

Hi @BobM10,

Welcome to the HP Support Community

I understand you are facing an issue with your HP ENVY 4520 All-in-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

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

Update the printer firmware
