Will not scan to computer, and not scan to email.

[Kardell]

The printer will not scan to the computer, (Scan Failed), nor scan to email. ((I use Thuderbird, and scan to  it worked fine with the HP prinbter I replaced.)   

If Firewall is turned off it scans to the computer.  But, when looking at the Firewall settings HP access is checked to allow through the Firewall. 

Same problems exist on both computers in the home network.  One is Asus, one is Dell

Windows "seems" to want to control the scan process.

Printing is fine.

Scaning from the computer, save to a file, works fine.

I have run the newest Printer and Scan Doctor

Hi! @Kardell, Welcome to HP forums.

I understand you have a scan to computer issue while scanning from your printer.

Don't worry I'd like to help you out.

Did you make any changes to your printer?

Are you able to make a copy from your printer?

Try the steps recommended below to scan to computer from your printer.

Restart the computer and printer

Restarting the computer and printer can restore a lost scan connection.

1. Turn off the printer.

2. Make sure the printer power cord connects directly to an electrical outlet and not through a surge protector or power strip.

3. Close all running programs on your computer, then shut down the computer.

4. Turn on the printer.

5. Turn on the computer.

6. Try to scan.

Try updating the printer firmware and check if it helps.

Uninstall the printer software from the root level and install the full feature printer software.

In Windows, search for and open Programs and Features. 
Select your HP printer. 
Select Uninstall. 
In Windows, search for and open Devices and Printers. 
In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.” 
Open up the run command with the "Windows Key + R" key combo.

      NOTE:

   Do not load photos in the ADF to prevent damage to the photos and the printer.

Select the file type you want to save, and then scan the item.

front corner of the scanner glass.
For more information, see Load original on page 11.

Beware they sent me a fix that locked up my computer.  The link to the install program was bad, I think.  Had to dd a system restore.  After 6 hours of work, calling now.   But,one part of it worked on my wife's computer, that is, check the Devices and Priners and drivers to delete the old HP printer drivers.  Still, no email.

@Kardell, Thanks for writing back to us.

I appreciate your efforts in trying out the steps.

As you mentioned the link to update printer drivers locked up your PC.

Please share the exact error or screenshot of the error to assist you better.

Also, I have checked the links and it seems to valid and works fine on my PC. Also, the links shared previously was for the HP Officejet 3830 running Windows 10 64bit.

Hope to hear from you soon!

Take Care! 🙂
