Envy 7640 will not scan

[coljldavidson]

My Envy 7640 no longer will scan.   For some time, it would not "scan to computer" from the printer, but I could initiate the scan on the computer and it would work.  It still says, "The connection to the computer has been lost" when scanning from the printer (i.e. it still doesn't work), but now it won't scan from the computer either.   I ran the HP Print and Scan Doctor and it scans a document and the printer says it was successful, but the Scan Doctor says, "The HP ENVY 7640 was not found."  Obviously it found it, but there is some problem.  It hangs displaying the "Finding and fixing scanning problems" window with the smaller "Scanning ..." window, but doesn't resolve the problem.

I have uninstalled the printer and then reinstalled it using the driver downloaded from the HP site, but it won't work.  It prints ok, but it won't scan.

Welcome to the HP Support Community.

Are you able to copy?

Let's try to do a root uninstall and reinstall of the software:

Unplug any USB cable, if any, before doing this.

1.) In Windows, search for and open Programs and features

2.) Select your HP Printer

3.) Select Uninstall

4.) In Windows, search for and open Devices and printers

5.) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose 'Delete' or 'Remove Device'

6.) Open up the run command with the "Windows key + R" key combo.

7.) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”)

8.) Click on the "Drivers" tab

9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom

10.) Select Ok

11.) Select Apply and Ok on the Print Server Properties windows

12.) Close Devices and Printers

13.) Open up the run command with the "Windows key + R" key combo

14.) Type c:/programdata and click Ok. Go to Hewlett Packard folder, remove any printer related folders & files.

15.) Restart the computer.

Once done, please download and install the software from here:
